Street Photography: Parallel Universe in Quebec City

Street photography: parallel universe in Quebec City
Street photography: parallel universe in Quebec City

This photo was taken in May 2015 in Quebec City, in Old Quebec, with a Canon 5D MKII. The store decorator has chosen a striking subject with this weird humanoid floating in silence in the presence of a green glass bottle in the foreground.

But a shot taken from the street would have only offered a simple picture with a weird subject. In choosing the side window to take the photo, many other dimensions could be integrated in order to increase the final impact.

1. From the side window, the photographer can add people’s reaction to the humanoid. But there is a bit of waiting involved until the appropriate persons pass by.

2. You can see multiple reflections from the front and side windows that are now visible in the sky.

3. The old architecture on the other side of the street offers a surprising contrast with the modernity of the main subject.

4. The eye naturally moving from left to  right, the humanoid’s head has been positioned in the upper right corner of the picture. Once the viewer sees the head, he then follows the blue poneytail to witness the reaction of the two persons on the sidewalk. The loop then starts again.

5. The orange element facing the humanoid offers a strong orange-blue complementary color contrast  that should not be neglected to increase the visual effect.

6. Finally, the converging lines help to add depth and increase the visual impact.

This is a photo that could have been much more standard if taken from the sidewalk. The fixed lens used was a  Canon 14mm 2.8L.

The CL-415 is on final for runway 11 at the Québec Jean-Lesage international airport. Each Spring, the Canadair Cl-215 and 415 pilots go through annual training before being deployed across Quebec territory in preparation for the next forest fires season. This picture was taken with a Canon 5D MKII. The speed was 1/320, aperture 8.0 and ISO 250 and a polarizing filter was installed on the lens. The photo was taken using a Canon 70-200 f2.8L IS II USM.

HDR Photography

HDR (High Dynamic Range) Photography

Quebec Bridge, 2012.

1. A picture you would never have thought possible, because of extreme contrasts between brightness and darkness, is now accessible to you through HDR.

2. For a good HDR picture, you need at least 1) an interesting subject 2) an appropriate setting or background 3) the appropriate light and 4) a wide range in contrasts. That seems basic, but HDR will not save a picture that was not thought through.

3. You need a software like Photomatix, to transform several pictures taken at different exposures into one HDR picture. But this is only the first step. You will also need another editing software to improve the general result after Photomatix has been used.

4. A tripod is required to help Photomatix align the pictures and create the HDR effect.

5. As with your normal pictures, it is always better to try to use the lowest ISO as possible.

Gruyères, Switzerland, 2013.

6. It is safer to work with manual focus. This way, none of your shots will have been influenced by external objects without you noticing. It will always be the exact same focus throughout the HDR photo session. With automatic focus, you generally notice your blurred pictures when you’re back home and then it is too late (it will often happen under low light conditions).

7. The greater the contrast, the more exposures you need to take (up to nine) in order to match the dynamic range of your eyes.

8. The idea is to take each exposure at a different exposure setting. If you need seven exposures, an example of settings would be: -1, -2/3, -1/3, 0, +1/3, +2/3, +1. You might decide that three exposures only are necessary and go for -2, 0, +2 or -1, 0, +1. The choice is yours but you must take only the required number of exposures to avoid including too much noise in your shots.

9. Throughout your HDR exposures of a specific scene, always keep the same aperture.

10. A scene is rarely perfectly balanced with light and shadows. If there are many shadow areas in the photo you want to take, then take more exposures over the recommended settings to ensure that you caught the whole dynamic range of the scene.

A house in Sainte-Pétronille, on Île d’Orléans, autumn 2012. HDR picture.

11. Inversely, if your scene has lots of highlight areas, take more exposures under the recommended settings.

12. Setting your camera to “automatic bracketing” is preferable because all the pictures are taken quickly thus avoiding to show any blurred picture in the final HDR picture. But if you want to show the movement of water in a creek, you don’t need bracketing: just take few shots with different time of exposure (in number of seconds). Just don’t overdo it otherwise it will give place to an uninteresting undefined white surface.

13. Check your LCD monitor so that none of the highlights are blown out. There would be a loss of details. For the same reason, you must avoid to block the shadows.

14. Always work with RAW files, it gives you better results. The RAW file already provides you with more f/stops then the JPEG file, and this before the transformation in HDR has even started).

15. Of all the lenses I’m using, the wide angle lens is my preferred one with it comes to HDR photography.

16. To improve the composition or enhance the general impact, crop the picture.

17. Not all pictures are appropriate for HDR transformation. If you want a dramatic silhouette as the final result, for example, HDR will not be appropriate. It will reveal too many details in the shadows and you will lose the high contrast effect that you were looking for. With practice, you will recognize where HDR is the most effective.

18. Whether you want a realistic picture or not, you can obtain surprising results with the combined effects of softwares like Photomatix, Topaz, Photoshop, Nik Software, Lightroom, Lucis Pro and so on. It’s only a matter of taking your time to experiment.

19. If you have only one picture on hand, like a shot you took years ago, and you would like to give it an HDR effect, you can use a software likeTopaz Adjust. There is an HDR effect section in that software that allows you to get a wide range of effects. But this is not going to be nearly as good as the real HDR resulting out of many pictures. The final editing step is, most of the time, done using Photoshop.

20. An unpretentious book about HDR is “Rick Sammon’s HDR Photography Secrets for Digital Photographers”. It is simple, colorful, well written and loaded with practical informations.

Photography and weather

Some cloud families

Cumuliform clouds add energy to any photo. Even photos in black and white benefit from them largely, whether it is for a normal or an HDR photo.

The stratiform clouds add to the tranquillity and the stability of a photo.

Clouds including a stratiform and cumuliform components (stratocumulus) produce an effect that is more energizing than the simple stratus, while avoiding the explosion of energy of the cumuliform clouds.

The cold front

The approach of a cold front enhances the possibility of interesting photos. If it is a fast moving cold front of moist and unstable air, the photos will probably be more spectacular, as some thunderstorms will be associated with the system. A dew point of more than 15 C indicates the presence of a lot of water vapor which can be transformed into precipitation, thus releasing a lot of energy. When these conditions are combined with a really strong contrast between the new air mass which approaches and the one which goes away, the produced meteorological phenomena will certainly be intense.

In the photos below, the meteorological system approaching the Quebec Jean-Lesage international airport also had to cross a small mountain range.

The morning fog

The morning fog offers many opportunities for interesting photos. You can choose an isolated tree and capture the combined effects of the morning sun and fog. Or you may choose a cluster of trees, for a completely different effect. Both photos below were taken in Domaine Cataraqui, Quebec City.

A morning fog resulting from a cold cloudless night will persist for hours if there is no wind. The cold morning air, motionless over a slightly hotter stretch of water, creates a fog that will finally disappear just before noon, when the atmosphere has been heated enough. If there had been an overcast sky during the night, chances are that the air over the water would have remained at a higher temperature, preventing the formation of fog.

The opportunities for more interesting photos arise when you witness the first holes in the fog layer.

The Ocean tugboats during a dense fog in the Bassin Louise in Quebec (2012).
The Ocean tugboats during a dense fog in the Bassin Louise in Quebec (2012).

We can take into account the season to estimate the speed of the diurnal reheating of the lower atmosphere. A morning fog will need more time to dissipate from late autumn to early spring: that leaves more time for the photographer to prepare. The forecasts can announce the disappearance of fog while it will not be the case if, over your sector, there is an invading layer of stratocumulus preventing the morning sun from reaching the ground.

To determine if the fog is going to dissipate as expected or will remain and possibly intensify, watch the difference between the temperature and the dew point on the hourly meteorological observations issued by weather stations near your place of residence. If the temperature and dew point spread increases, the fog is going to lift. If the difference between those two decreases, the fog is going to persist and possibly intensify.

The mist

The mist can be qualified as such when the visibility is superior to ½ mile, but do not exceed 6 miles for an observer on the ground. If the visibility is of ½ mile or less, it is called fog. This photo of the Bic National Park, near Rimouski, shows the interesting effect that the mist adds to a beautiful landscape.

Hot and unstable air in winter

When there is a warm and unstable air advection (about 0 degrees) while winter has already settled, there are good opportunities for photos. A moderately developed cumulus produces significant snow showers and this snow sticks on all the surrounding objects. All that snow would have begun to melt on contact of objects if the latter had had a temperature superior to zero degree. But, the winter being already settled, the snow persists. It gives enough time to capture some souvenirs.

The local effects

A photographer might benefit from learning about the meteorological local effects influencing the regions he intends to visit. The local effects are often simple to understand and they repeat themselves regularly, according to wind and season changes. The knowledge of these effects allows the photographer to be ready and position himself even before the phenomenon occurs. It limits the comments like: “If I had known that it would occur, I would have settled down here one hour earlier!

The local terrain as well as large size bodies of water produce predictable meteorological phenomenon that can be used by a well prepared photographer. It can consist of persistent fog, repetitive snowstorms over a small sector, strong winds, cumuliform clouds alongside the mountain summits, etc. By being positioned at the right place, at the right time, the desired photo can be realized.

A change in the wind direction

A change in the wind direction suddenly increases the opportunities of interesting photos. It might announce the approach of a cold front, a warm front, a sea or land breeze, etc. In the photo below, a bit of fresher air suddenly began crossing the St-Lawrence seaway at the end of the day, thanks to the approach of a weak cold front. The water was still relatively warm and the moisture which was present over the surface became visible due to the cool air supply. The conditions were now ideal for a short-term thin fog, as long as the wind speed would not increase. Just in time for a photo.

Familiarization with weather radars

It can be useful to get acquainted with weather radars which, for the needs of photography, remain simple to interpret. Multiple echoes of small dimension with a steep gradient of various colors indicate precipitation resulting from cumuliform clouds. The showers associated with these clouds are often moderated or strong and will be the result of approaching towering cumulus or cumulonimbus (thunderstorms). A towering cumulus presents a dark base and a white summit to the photographer. At sunset, their vertical development can be used to emphasize the last rays of light.

Large echo areas of similar colors of low intensity indicate a relatively stable air generally producing steady light rain or drizzle. This should be understood as a possibility of increased humidity limiting the visibility through mist or fog.

Hoar frost

Hoar frost is a short-term phenomenon. It is thus necessary to capture the scene before the sun melts everything. The photo below shows some small twigs on which hoar frost has settled. It was taken at the beginning of the seventies. Although the quality of the photo is not exceptional, the meteorological phenomenon is well demonstrated.

Forest fires

Wishing to make photos of western Canada during summer 2014, I came up against a season where hundreds of forest fires were raging. The smoke was covering some parts of Alberta and British Columbia. Some fires were important enough to require the closure of the sole highway connecting Lake Louise to Jasper. I thus decided to include the effects of those fires in the holiday souvenirs.

A visibility reduced in forest fire smoke allows a photographer to obtain, without special editing, sunsets with interesting colors.

The smoke also produces an effect similar as fog, but a fog which would be impossible to obtain at the end of a summer afternoon while the sun shines and there is a 38 degrees Celsius temperature.

Flowers and plants photography

Butchart Gardens, British-Columbia, 2012.
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.

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.

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.

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:

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.

Several ships naviguate along the Hudson Bay and Ungava Bay up in Northern Quebec, in the Nunavik, during summer. Sometimes, as flight service specialists  (FSS) working for Transport Canada, we are allowed to get on board to take few pictures, like it was the case for the two photos above.

When a ship makes a long journey towards the small villages along the Hudson Bay and Ungava bay, it regularly strikes small pieces of ice. The crew has to determine if the boat’s hull will be resistant enough to stay on the desired path.

Unfortunately, it is not always possible to evaluate the situation correctly and the hull sometimes breaks under the impact with the ice. The photo below shows the ship Kanguk, off Inukjuak in autumn 1982, its hull damaged during its journey towards one of the small villages along the coast.

Winter means fun in Sillery

Snow, ice and wood creation made by a Sillery citizen in Quebec City in 2015.
Snow, ice and wood creation made by a Sillery citizen in Quebec City in 2015.

A retired couple in Sillery, Quebec, decided to add life and color in front of their house. Initially, the intention was to make a big snowman. But the project was progressively modified and a couple was eventually created. It is made of snow, ice and a bit of wood to ensure that the most fragile parts will be able to sustain the whole winter. A projector has been installed and is turned on as soon as night approaches. It is again a proof that there is no limit to imagination, and that it is not age related.

If there is a photographer out there wandering what are the picture specs, here it is: Canon 5D MKII, F22, ISO320, Canon14mm 2.8L lens, tripod and cable.

1. Ensure you bring : tripod, remote cable, flashlight and timer.

2. Use of RAW (.TIFF) is highly recommended. There is a greater potential for corrections afterward, if something is not according to your taste.

3. Noise reduction activated on the camera.

4. If the winds are calm: ISO between 50 and 200.

5. If there are strong winds: ISO 400 might be useful to avoid a blurred picture caused by the continual small vibrations of the tripod due to a long exposure. That is why a heavy tripod is always preferable.

6. If you wish to take a picture of people moving at a normal pace, and you have access to quality lenses, it will often be necessary to use ISO 800 to get a clear shot. This setting could allow the shutter speed to be adjusted at about 1/200 which is plenty to obtain a picture that is not blurred; that is unless you are not using a long focal like 200mm or more.

7. For people shots, it is better to have your back to the remaining light on the horizon, unless your goal is to capture a silhouette.

8. For extended exposure, use the autofocus “one shot” setting until it stops working due to insufficient light. Then use manual focus. Or use manual focus all along, with Liveview, if you prefer it that way, for extra precision.

9. Mirror lock-up function must be activated to avoid vibrations caused by the shutter action.

10. Use a remote cable when taking the picture to avoid useless vibrations.

Old Québec at dusk
Old Québec at dusk.

11. If you wish, you might think of selecting a specific AF point to ensure a better focus if there is a small area that matters the most to you in the picture.

12. Do not use the FULL AUTO mode during night photography.

13. The three most important modes are 1. Aperture (taking care of slightly overexposing for surrounding lights) 2. Speed 3. Manual. There is one more reason to overexpose a bit if you work with the RAW format: there is more data information in light than in shadow, so once the picture is taken you have access to more data to play with to adjust the dark sections of the picture.

14. If you expect an exposure longer than 30 seconds, use BULB mode.

15. Night pictures are best taken using the camera bracketing funtion (-1,0,+1) and this, every two minutes.

A Christmas tree in Sillery

16. The best period for night shots is 15 minutes after sunset, until official night time, which you can find on the internet. As this period is quite short, it is important that you know in advance what is of interest to you and where you will position yourself when comes the time for the picture.

17. Total darkness is not what is the most favourable in night photography. But you can certainly obtain interesting results using black and white.

18. Beware of surrounding light reflection in your lens.

19. Histogram has to be reviewed to ensure that there is no serious overexposure.

20. It is preferable to choose an aperture between F11 and F16 for maximum sharpness as well as an adequate depth-of-field.

21. If shooting a subject against the remaining light over the horizon, there might be quite a contrast in lighting between where you stand and where your subject is positioned. You might think of using grad filters (3-6-9-10) to help correct this huge light difference, or you can transform the standard photo session into an HDR one. Or both! There are also filters specifically designed for sunrise and sunset periods that can improve your shots.

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.

Quai des Cageux, Québec 2012.
Quai des Cageux, Québec 2012.

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.

This photo was taken during a one month trip around Hong-Kong in 1990. The average quality of the picture is due to multiple processings necessary to show it on the web. Few other chosen photos about that trip have been posted in the “Photo galleries” section, under “Asia”.

The period when those junks were taken was exactly one year after the Tiananmen Square massacre. The South China Morning Post wrote that 100,000 people walked near Victoria Park to commemorate the tragedy. It was possible to see the crowd from the window of our Cathay Pacific Boeing 747-200 while flying over Hong-Kong for the final approach towards the Kaï Tak airport.
