Choosing what is important in a camera

Since there is actually no camera that has everything, whatever the brand, the buyer of a new camera must make choices: the type of sensor, the number of megapixels, the weight and size of the camera, the automatic focus’s speed and ability to follow a subject, the number of images per second, the performance under low light, the possibility to greatly enlarge a picture while maintaining its quality, advanced video functions, electronic communications with other devices, an extensive choice of lenses, etc. The list can be quite long…

The Canon 5DS(R): a specialized camera

A photographer happy with the Canon 5DS or 5DSR is one who needs a specialized camera offering both sharp images and the possibility of greatly enlarging the pictures it takes while maintaining the initial quality. This camera allows for more creativity as the possibility of extreme cropping beats, for now, everything that is on the market in the DSLR format.

Testing the potential of the Canon 5DSR when it comes to enlarging a picture

Here is an example of what this means: the photo below shows the yellow M of the McDonald’s restaurant photographed with a 50mm lens. Not easily visible…

Mc Donald's restaurant's yellow M captured with a 50 mm lens. Hard to see, of course! — Mc Donald’s restaurant’s yellow M captured with a 50 mm lens. Hard to see, of course!

Then the next photo was taken with a Canon EF 70-200mm f/2.8L IS II USM telephoto lens set at a 200mm focal length.

Testing the Canon 5DSR: the Mc Donald's restaurant's yellow M enlarged through a Canon EF 70-200mm f/2.8L IS II USM telephoto lens. Focal length used: 200mm. — Testing the Canon 5DSR: the Mc Donald’s restaurant’s yellow M enlarged through a Canon EF 70-200mm f/2.8L IS II USM telephoto lens. Focal length used: 200mm.

But the picture can be enlarged a lot more using the amazing resolution of the Canon 5DSR. The following picture shows the result after cropping the 200mm image: the yellow M now takes the whole vertical space available in the picture without any loss in quality.

The Mc Donald's restaurant's yellow M, after having been enlarged (focal 200mm) and cropped within the Canon 5DSR. — The Mc Donald’s restaurant’s yellow M, after having been enlarged (focal 200mm) and cropped within the Canon 5DSR.

From my position on the hill, the yellow M was barely visible with the naked eye. By using a 200mm focal length, followed by serious cropping, I was able to obtain the result above. So it is possible to photograph a subject that is almost invisible without a telephoto lens and transform it into the principal subject of the picture without any loss in quality.

I chose the 5DSR because the anti-aliasing filter has been neutralized in the model R to offer even sharper images, although there is a risk of occasional moire effect when there are repetitive patterns in a scene. This is the compromise that Nikon users must also have to deal with.

Rethinking photography

The 50.6 megapixel full frame sensor in the Canon 5DS or 5DSR allows a new approach of photography for those who do not have access to a much more expensive and larger medium format camera that does not necessarily give really superior pictures.

When I go outside for a photo session, it seems to me that I now carry a huge telephoto lens without the weight and the cost. A lot of what seemed to be unavailable possibilities are now accessible.

Taking pictures of people in the street is now less complicated: there are no more suspicious looks, artificial poses or people hiding their face. This is an ideal camera to capture people acting naturally without disrupting their routine. Gone is the feeling that you are bothering them in any way.

Quartier Petit-Champlain Old Quebec May 2016

The photo below was taken while I was standing at least 300 meters from the scene, just after sunset. For those who are from Quebec City, I positioned the tripod on a high wall on the other side of Chemin St-Louis, near the St. Louis Gate. I had to slightly brighten up the picture to make the details more visible, risking at the same time to increase the digital noise. It was a May 2016 warm misty evening, which is clearly visible by the lack of details in the background as we look in the distance.

But those are not the only possibilities of this camera. The Canon Company, in its promotional video, explains what exactly the camera was designed for:

How can someone maximize the use of a 50.6 megapixel full frame sensor

In order to bring a subject closer to you while fully benefiting from the Canon 5DSR 50.6 megapixel full frame sensor, it is obvious that there must be absolutely no vibrations. The photographer must therefore use a tripod, a remote control release and the mirror lock-up function. This allows for a very low ISO setting while avoiding a blurred picture.

The mirror lock-up function is very well thought through, with the possibility to choose a totally automatic processus according to a timing chosen by the photographer (between 0 and 2 seconds). The system eliminates any secondary micro vibrations.

In order to ensure an even better picture, the photographer must use Liveview and set it to the 16X enlargement available on that camera (versus 10X on my Canon 5D MKII) to manually adjust the focus. It is then possible to see the slightest vibrations caused by the wind. Doing so, I realized that my camera strap, lightly swaying in the wind, was causing some minimal vibrations. Every detail taken into consideration will improve the final result.

One must then ensure to immobilize the strap and even diminish the tripod height if possible when the wind is blowing. These steps will allow an incredible enlargement of a subject while maintaining the initial quality of the image offered by a full frame sensor.

Superior mirage effect (cold mirage)

The photo below shows a ship being helped by two Ocean tugboats on its way towards the Quebec Harbour. The ship was at a good distance from the harbour; it is then possible to witness the superior mirage effect (cold mirage) resulting from a temperature inversion immediately over the water. The boats are deformed but the important close-up has not lowered the image quality. It has instead allowed to increase the atmospheric phenomenon effect.

Once closer to the Quebec Harbour, the cold mirage effect decreased, as shown on the picture below:

The Canon 5DS or 5DSR without the use of a tripod or mirror-lock

Obviously, a tripod is not necessary if you do not intend to use a lot of cropping to enlarge a photo. You will obtain excellent results with the hand-held camera providing that you remember that this Canon DSLR is a specialized tool.

So many megapixels on a sensor of that size require that the photographer adapts his technique. But, as you can see from the picture below, it is totally possible to capture an aircraft in movement, even at dusk (May 11, 19:49), when the camera’s parameters are correctly adjusted. A higher shutter speed than normal is, in this case, absolutely mandatory.

The focal length was only 140mm and the shutter speed 1/1000. The lens was equipped with a polarizing filter and the photo taken when the vessel was approaching the Quai des Cageux.

The colours produced by the Canon 5DSR

The digital processing of the image and colours produced by the Canon 5DSR require different adjustments than what was necessary with the Canon 5D MKII. I am still learning how to handle the results produced by this camera so I will wait a bit before commenting.

Night photography

Here are two photos taken during the evening in Quebec City. The photo below required a 200mm focal, an ISO set at 4000 and a shutter speed at 1/30 in order to obtain something else than trailing lights. Luckily, the traffic was moving slowly…

The picture below, taken with a 200 mm focal, required an exposure time a bit longer that one second with the ISO set at 800. To take the photo, I took advantage of the fact that the cars were momentarily stopped at a red light, so that they would be clearly visible.

The images per second of the Canon 5DS(R)

The Canon 5DSR is so far quite an impressive camera. I would have appreciated that Canon offer a higher rate of images per second (7 instead of 5) to make it more versatile.

The camera allows taking pictures with smaller formats than 50.6 MP, the two other options being 28 MP and 12 MP. If the camera can deliver five images per second with 50.6 MP RAW files, we can deduct that it is able to offer more speed for smaller formats. But the camera is blocked at 5 IMS so that it, I suppose, does not compete with other existing Canon models of the same category…

Nonetheless, Canon says that the rapid sequence of shooting lasts longer if the photographer uses the smaller files provided. So it is not faster, but it keeps on firing for a longer period. My guess is that it would only require a new firmware version to improve this camera’s number of images per second.

Aviation photography: Quebec’s CL- 415s heading towards Fort McMurray, Alberta

Post author By Stanley
Post date 9 May 2016

A Bombardier CL-415 water bomber, property of the Government of Quebec, is being prepared for its flight towards Fort McMurray, May 2016

Quebec’s CL-415s helping out in Fort McMurray

On May 5th, 2016, according to what had been announced by the Government of Quebec, four CL-415s took off from the Quebec Jean-Lesage international airport (CYQB) heading to Fort McMurray, Alberta, to help in the fight against widespread forest fires in that province. It is the worst natural disaster that Canada has known in its history.

Preparing flight crews and aircrafts for such a long cross-country trip naturally demands much coordination from the SOPFEU (Society for the protection of forests against fires). Once they will have landed at the Fort McMurray airport, the pilots of those CL-415s will be under the direct command of the Albertan authorities in charge of fighting the wildfires, since the latter are best positioned to know exactly what the local needs are.

I figure that the flight service specialists (FSS) of the Nav Canada flight information center (FIC) in Edmonton must have quite busy days with the increased aerial activity associated with the numerous fires…

Crew members are walking towards the Government of Quebec CL-415; they will soon be airborne and heading to Fort McMurray in Alberta, to fight the forest fires (2016)

The picture above shows crew members heading towards their assigned aircraft. Once they start working in the Fort McMurray region, they will not only have to directly fight the forest fires but also head to sectors that have not yet been touched by fire and water the area thoroughly to prevent new wildfires.

A Government of Quebec CL-415 number 245 is taxiing at the Quebec Jean-Lesage international airport to take-off towards Fort McMurray, in Alberta, to help fight the out of control forest fires in that province during May 2016.

Taking pictures of propeller-driven aircrafts

It is a bit touchy to photograph propeller-driven aircrafts while making sure that there is a sensation of movement. In a natural reflex to want to avoid blurred pictures, the photographer uses a shutter speed that corresponds to the focal used for the shot. In the case of the picture above, the focal was 400mm. But if a shutter speed of 1/400 had been used, the propellers would have been totally immobilized and the aircraft would have looked like its climbing while not using its engines.

It was necessary to reduce the speed to 1/160, thus increasing the risk of obtaining a blurred picture. In order to get both image sharpness and moving propellers visual effect, the photographer has to follow exactly the movement of the aircraft with the camera so that it looks totally immobile in the viewfinder. This asks for a bit of practice but allows for more realistic photos.

The government of Canada helping out Alberta’s citizens

The government of Canada, under Justin Trudeau, has promised to match the amounts of money offered by all Canadians to the Red Cross society toward helping the Fort McMurray population.

Obviously, its contribution will not stop there (in fact, far from it), but the message is for the whole Canadian population to contribute generously to support the efforts of the Red Cross. It is already estimated that the material damages will reach at least nine billion dollars and that numerous years will be required to rebuild everything. The Liberal Party of Canada had built its political campaign around the need to invest for the renewal of infrastructures. With the Fort McMurray fires, there will be plenty of new unplanned expenses ahead.

More than 1,400 firemen are fighting the wildfires. So few, there has been very few lives lost, although “very few” is always too much. The crisis is, according to everyone, well managed by the government of Alberta.

At the time of writing, there was still no rain forecasted for days to come and the drought was also extending to the southern half of Saskatchewan and part of Manitoba. The winds were expected to increase, which would mean that even more resources would be needed in the near future to bring those wildfires under control.

It seems to me that the government of many Canadian provinces would benefit in acquiring new water bombers like the CL-415 to give them an increased margin of manoeuver that would allow them to react more quickly, if we take into account the tendency for the ever growing number and size of forest fires. In the picture below, the government of Quebec CL-415 number 247 is just airborne from Quebec to Fort McMurray.

The CL-215s will not head to Fort McMurray

While several CL-415s are leaving for Alberta, few water bombers, like the two Canadair CL-215s shown below, stay at the Quebec Jean-Lesage international airport in case of forest fires in the province and also to be used for the seasonal rehearsal needed for every pilot before they are dispatched across the province of Quebec.

Global warming

Some people can say that global warming is not responsible for the increasing number of extended wildfires. They might be right, but I prefer to adopt a wider view than only what is going on in Alberta. Heat transfer between the north and south are now more extreme in order to equalize the temperatures around the globe. All means to reduce the difference in temperatures between the equator and the poles are at work and this causes increasing problems to particular regions.

The Kamloops region in British-Columbia, when numerous forest fires were raging 2014.

A powerful El Nino phenomenon, repetitive Omega blocks, the air circulation in different cells (Hadley, Ferrell, polar, Walker) all participate in the heat exchange. At a more reduced scale, we also regularly hear of cold and warm fronts in the meteorological forecasts.

It is certainly not local warm fronts that are responsible for the fact that a thinner layer of permafrost is unable to ensure the stability of Arctic runways anymore. Nor are fronts responsible for the fact that houses on stilts do not have a stable foundation anymore. Many heat records have been established these past years in northern Canada. There will certainly be large amounts of money to spend to rebuild the Nordic infrastructures.

Brush fires as soon as April in Alberta

This year, as soon as April, there were widespread brush fires in a region as north as Fort McMurray in Alberta because winter has not brought much snow to humidify the land during Spring. I thus wondered what would happen once in July. Albertans did not need to wait that long to get the answer.

Western Canada forest after a fire (2014)

The modelization of climatic changes indicates that, in the Fort McMurray region, the forest fire season is already fifteen days longer that it used to be. More heat might favor more droughts. But an increase in temperature also favors the development of thunderstorms and with them comes lighting that will start up new fires.

One thing is sure: insurance companies will not lose time with the different theories on global warming. The reinsurers (those who insure the insurance companies) have the obligation to limit their losses to stay afloat and premiums will quickly increase to answer to the thousands of claims following an increasing number of natural disasters.

In the photo above, it is possible to see a FedEx ATR 72 (C-FTAR) taxiing toward the ramp after a landing runway 06. An Air Canada Express Bombardier DHC-8-402 (Q-400) (C-GIJZ) was also being towed for is imminent departure.

ATAC’s Hawker Hunter N339AX

Being in luck, I was able to capture a Hawker Hunter (N339AX) belonging to the American company ATAC, just airborne from Quebec. As for any military jet, it is difficult to ignore them on take-off: the reactor’s noise is there to remind you of their presence…

The pictures above have been taken with a Canon 5D MKII camera, equipped with a telephoto lens Canon 70-200 f2.8L IS II USM with a polarizing filter and a Canon Extender EF 2X III which brought the focal length to 400 mm. Even then, more cropping was necessary to enlarge the aircraft since I was quite far away from the runway.

Wishing to ensure that the image was sharp (a blurred picture is more probable with a 400 mm focal length while the photographer attempts to follow a fast flying jet), I adjusted the shutter speed to 1/1600 and made sure that the automatic focus was set on AI servo.

I now realized that a slower speed could have worked a bit better since it would have allowed showing a blurred forest in the background while keeping the aircraft sharp. But it is not often that you have the opportunity to see a Hawker Hunter in flight these days and I played safe with the shutter speed. The ideal shot will be for another day…

Photography in Europe: Gruyères and the Moléson in Switzerland

Post author By Stanley
Post date 2 May 2016

Gruyères and the Moleson in the background, Switzerland 2013

The city of Gruyères is located in the Prealps, in the Friburg County in Switzerland. It is a very charming small medieval town where cars are forbidden (the white van shown in the picture above is only used for morning delivery). In the city, one can visit the Gruyères Castle (Château de Gruyères), the H.R.Giger Museum (creator of the “Alien” in the movie Alien), the Tibet Museum, a cheese factory and boutiques. There are also some restaurants.

In the picture above, shot with a Canon 5D MKII, it is possible to see the Moléson in the background, a mountain that rises only 512 metres above the surrounding terrain but is still at more than 2000 meters above sea level. It is a tourist attraction that should not be neglected since it is very well equipped for all types of visitors, with a funicular and cable car. The visitors also have access to very interesting walking paths, for all ages and experiences.

Moleson cable car, in the Gruyeres region, Switzerland 2013

When you use a cable car and do not see where it is leading due to the presence of clouds, you have to trust human engineering. But we are in Switzerland, so it should be all right!

The Moléson summit offers superb views. The small cumuliform clouds visible in the morning around the mountain progressively lift up due to daytime heating and eventually become beautiful cumulus clouds that add life to any pictures.

Once on top of the Moléson, it is possible to use a modern metal stairway to gain even more height and access a platform allowing an unobstructed panoramic view. The picture above was taken with a Canon EF 16-35mm f2.8L II USM wide-angle zoom lens equipped with a polarizing filter.

Metal stairs leading to an observation post on top of the Moleson, Gruyeres region, Switzerland 2013

When ready to go down the mountain, the visitor has two choices: travel with the cable car and funicular he used when coming up, or slowly walk along an easily accessible path through beautiful green landscapes. The more experienced trekkers might decide to walk along the crests of surrounding mountains. We chose to walk on paths covered with flowers.

Back to Gruyères, a visit of the Château de Gruyères and both museums is a must, as well as a tour of the cheese factory. You might want to spend some time in the boutiques too and try the local restaurants. It is also the moment to take a few pictures…

Inside the Gruyeres medieval city, Switzerland, 2013

The old architecture of the buildings in Gruyères as well as the neighbouring countryside allow for very interesting photographic compositions. A well-known photography technique consists in using an opening in a building and using it as a second frame (a frame within a frame). I made sure that the background was clear enough to improve the visual effect. An aperture around 16 allowed for an appropriate depth-of-field.

Spiraling stairs in the Gruyeres Castle, Switzerland 2013

The picture above shows a spiraling staircase inside the Château de Gruyères. I can barely imagine what the results would have been if I had had access to the new Canon 11-24mm wide-angle lens. But nonetheless, the Canon EF 16-35mm f2.8L II USM zoom lens did a good job.

The beauty of the full frame sensor mounted on the Canon 5D MKII DSLR is that a wide-angle shot taken at a 16mm focal will stay at 16mm while with a smaller sensor, like the APS-C, the photographer is facing a conversion factor of 1.5 or 1.6X, which transforms the 16-35mm wide-angle into a 24-52mm, in the best of cases. The APS-C sensor is interesting when used with a telephoto lens but a bit less when comes the time to take wide-angle shots.

The picture below presents the Château de Gruyères seen from a neighbouring field.

Gruyeres old architecture, Switzerland 2013

As the sun was setting down, I tried a shot from inside the castle. It was interesting to see the two little boys standing up alongside the wall and admiring the sunset. At the same time, it was possible to see the Moléson in the distance, its summit hidden in the clouds.

Due to the strong light contrasts, it was necessary to use a Hi-Tech ND graduated filter installed on my Canon 16-35mm wide-angle zoom lens. The Digital SLR Photography magazine, in one of its recent editions, made a comparison between ND grad filters and indicated that the Hi-Tech filter had a slight magenta coloration instead of a neutral grey. I think it is easily visible in the picture below. The photo could have been corrected with Photoshop but I thought of keeping it as it was since the scenery looked somewhat unreal already.

Once the sun was below the horizon, the more subtle colours gave a totally new look to the countryside. On the picture below, it is possible to see on the right a small path that a visitor can take to head down to the nearby village.

Gruyeres region in the sunset, Switzerland 2013

All the sceneries are not that easy to capture and it is sometimes necessary to use HDR photography to extend the dynamic range and take care of extreme light contrasts. The photo below needed five different exposures that were subsequently processed with the Photomatix image editing software. Useless to say, it was necessary to use the mirror lock-up function, a tripod and a remote control release.

Here is, as the final picture, an idea of what is waiting for you at the H.R. Giger Museum. If there is a strange but very interesting museum, it is this one.

Flowers and plants photography

Post author By Stanley
Post date 4 April 2015

Butchart Gardens, British-Columbia, 2012.

Facing a field of flowers, a photographer has to choose among many possibilities. Here are just a few:

1) He can choose a really beautiful flower and make it the sole point of attraction. In that case, he must decide if the background will be free of any distractions.

A rose from the English Garden in Geneva, 2013.

2) He can profit from a blurred background that is of a color dramatically opposed to the color of the chosen flower.

A tulip in the Bois-de-Coulonge, Québec City.

3) He might favor an overhead or a low angle shot. As this choice of the angle of view does not apply only to flowers, I found in my archives a low angle shot of a pear tree located in St-Nicolas, Québec. Here it is, so that you can see what kind of effect can be obtained.

4) He can decide to show many flowers on the same picture, considering the interesting impact produced by all the color dots.

A field of flowers in Saint-Nicolas, Québec.

5) He might also use the flowers as accessories to direct the eye of the viewer to another point of interest like, for example, a building with special architectural characteristics.

The flowers and the bumblebee are two interesting subjects; they complement each other in this picture. It would be hard for me to decide which one I prefer.

Bumblebee on a flower in the Parc du Bois-de-Coulonge, Québec City

Unless there is no other possibility, it is better to avoid shooting flowers under full sun as there will be considerable reflection on their petals. If you have no choice, use a polarizing filter, well adjusted, to reduce the undesirable effects of direct sunlight.

The ideal day to get out and take pictures of flowers is a day without wind, where there is a bright light but dimmed by an overcast sky.

The quality of colors and contrasts will be maximized if the pictures are taken during the morning or at the end of the afternoon.

Aperture has a definite impact on the final result. With a wide aperture (smaller numbers like F2.8 or F4.0) you will get a sharp subject with everything blurred around it. This will make your flower stand out. With a small aperture (bigger numbers like F14, F16), both foreground and background will be sharper, with an even better result using a wide-angle lens. Your flower will lose a bit of its impact as all the elements in the picture will now shine. Below is a picture taken in Ontario, during the Ottawa Tulip Festival.

Macrophotography:

April 2012 on the Plains of Abraham: A bee makes its way out of a crocus.

1) Remove any dirt from the plant you want to capture and choose a plant whose petals are in perfect condition.

2) Use a tripod, a remote control release and the mirror lock-up (MLU) function for better results.

3) The camera should ideally be used with manual focus, for improved sharpness. In order to verify if the picture will be in focus, look at the LCD screen and enlarge the picture (5X or 10X). You will immediately see if a minor adjustment is needed to get a sharp photo or to improve the depth-of-field.

The histogram should be checked upon taking the picture to immediately compensate for the necessary amount of light.

You can use a flash to reduce aperture. You must adjust it so that it’s not shooting at full power otherwise there will be too much reflection and you will lose all the delicate nuances of colors and contrasts.

A method that will produce surprising results is called “zoom burst”. You slowly move the zoom of a lens on all its focal length while the shutter remains open during the process. You must select a speed that is slow enough to accommodate the full deflection of the zoom. You should know that many shots are normally needed before you get a satisfying image.

Every lens offers different possibilities:

1) The macro lens is useful if you wish to capture very precise details on the flower. To add an interesting effect, you can even spray the flower lightly with water so that a few droplets remain on the petals.

2) The wide-angle lens allows you to transform an image and give it an original perspective. The effect will be more important if you shoot the flower from a special angle like, for example, from the ground up. If you must lie on the ground, use a little carpet to keep yourself clean and dry. I bought a right-angle finder to ease the workload when shooting under complicated angles. This could be a potentially interesting addition to your equipment.

3) Finally, the telephoto allows you to pick a particular flower and, because of compressed perspective, offers you a background filled with multiple colors.

Let’s end this section with a mushroom picture. The same principles apply with regards to simplicity, settings and angles of views. I could have chosen to show only an oversize shot of a mushroom, or take only part of it, but I preferred an approach that would allow me to show the radically different shapes of the specimens found at the Laurentian Forestry Center in Québec.

Aperture, ISO and Speed

A Decision Has to be Taken

You must decide the ideal combination between the following: aperture, speed and ISO. All three are interrelated and choosing one has a direct influence on the other two.

You are facing a beautiful landscape in which you want everything to be in focus: you decide that the aperture is what matters the most. Choosing aperture as the priority is a very popular choice. Let’s consider that you choose F16, which should give you a very interesting depth-of-field but will demand a lot of light. You have to compensate somewhere. If there is not much movement in the scene, and you have access to a tripod, you might decide to choose a slow speed, which allows more time for the light to enter the camera. Doing so, you won’t need to crank the ISO and you will avoid adding useless noise to your picture.

In the picture below, aperture is set at F16. The vegetation in the left corner draws the viewer’s eye toward the pedestrians, and then progressively to the quai des Cageux. We finally see the Quebec bridge, the longest cantilever bridge in the world.

If you decide that speed is a priority, you will have to compromise ISO or aperture. ISO will have to be increased to improve light sensibility, but doing so will increase the size of the grain in the picture. Depth-of-field will have to be adjusted as well since a higher speed does not let much light enter the camera. You won’t be able to pick F16 this time. So you will eventually find that there are some out of focus areas in your picture. With a bit of practice, you can be less demanding on the speed, providing you can follow the subject with your camera (it is like if you were slowing down the subject, so less speed is required).

The picture below was a bit particular: it was taken when I was on a boat rocked by waves. The eagle was far away and was traveling in the opposite direction, thus increasing the relative speed of the subject. The Canon 5D MKII was hand held and 400mm focal was necessary. Speed was crancked at 1/1600 and the ISO required was set at 5000. Naturally, the grain in the picture being larger, slightly diminishes the quality. This was a necessary compromise if the eagle was to be taken in flight.

It is getting dark and you want a photo with absolutely no noise and you decide that the aperture is what matters the most. You make no compromise and choose ISO 50. This setting requires a lot of light, because the lower the ISO, the higher the demand for light. In order to make sure that your picture will not be blurred, a tripod will be necessary, since there will be an extended exposition time. In the picture below, the shutter has been opened for ten seconds, with a 9.0 aperture, 200mm focal and 50 ISO. Only the small branches in the foreground are blurred.

Note: in general, it is better to use a tripod as often as possible, even in daylight, in order to optimize quality. Choose a heavy enough tripod to prevent vibrations under windy conditions. A light tripod is easy to carry but does not allow for acceptable pictures in adverse weather. It’s obvious that this Queen Mary II photo would not have been as precise if a light tripod had been used. In this case, it would have meant that continual vibrations would have been recorded during 10 seconds. The boat would have been totally blurred.
