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…

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.

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.

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.

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 photo below shows the Maersk Pembroke container ship photographed with a hand-held camera using a Canon EF 70-200mm f/2.8L IS II USM telephoto lens during Spring 2016 near Quebec City. 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.

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.

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.

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.

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.
