The picture above has been taken with a Canon 5DSR full-frame camera in the Port of Vancouver, in British Columbia, during summer 2016. Following a very busy day of take-offs and landings, everything is now peaceful. The Harbour Air Twin Otter floatplane C-GQKN and Turbo Otter floatplane C-FODH are now parked for the night.

Pictures taken at dusk or dawn benefit from a unique light. Nonetheless, taking pictures of aircrafts against the light, with the last sunrays still visible, requires a special attention with regards to blown out highlights.

When contrasts are too important, it is possible to correct the situation by taking several pictures with different exposures and merging them using an image editing software like Photomatix (HDR photography). This is done in a few minutes only. Nonetheless, with floatplane aircrafts that are still slightly moving even when tied for the night, there is an increased risk of a blurred picture. The best way to proceed is to use a ND grad filter and to place it exactly where the light is the strongest. Naturally, there will still be some blown out highlights.

This being said, you still have a good margin of manoeuver, since there is no problem in showing a limited amount of over-exposed highlights in the brighter part of the sunrays, as there is not much details to lose there anyway. While purists would argue otherwise and spend hours in front of their computer trying to correct everything, you are making the best of another day of photographic exploration.

If the picture was taken using RAW files (or RAW with JPEG), it is possible to improve the scene even more by correcting some aspects like the contrasts, the brightness, the colours, the saturation and ambient light, etc. This also requires very limited time in front of the computer once you understand the basic principles of an image editing software.

Aviation photography: when rain helps the photographer

It looked like it would be an average day for a photography session at the Vancouver Harbour. The sky was quite ordinary, which means totally cloudless. But around noon, a new and more humid air mass made its way in British Columbia and rapidly the blue sky was replaced by clouds and precipitations. At the same time, the high intensity light that was prevailing around noon suddenly took more acceptable levels for photography.

Pilots of different bush floatplanes like the Twin Otter (DHC-6), Turbo Otter (DHC-3T) and Beaver (DHC-2) had to deal with the sudden weather deterioration in order to complete the daily planned flights. But one man’s loss is another man’s gain. For aviation photography, low clouds and light intensity meant that the pictures would be more interesting.

The photo above was taken with a Canon 5DSR full-frame DSLR camera equipped with a Canon 70-200 f2.8L IS II USM telephoto lens. In order to capture the moving propellers, I had to set a low shutter speed. The scene was then cropped to avoid visual distractions. The 50.6 megapixels full-frame sensor of the Canon 5DSR facilitates cropping when it is required.

In the foreground, there is a Harbour Air Twin Otter floatplane (C-GQKN) approaching to land in the Vancouver Harbour. In the background, far away and in the superior right corner of the photo, the pilot of a Turbo Otter floatplane also deals with worsening weather while ensuring that he maintains a visual contact with high ground obstacles surrounding the harbour.

Aviation photography: a Twin Otter floatplane lands in Vancouver Harbour

Westcoast Air Twin Otter floatplane C-FGQH arriving in Vancouver Harbour, in British-Columbia, during Summer 2016. The photo was taken with a Canon 5DSR camera.

The picture above was taken in British Columbia, during summer 2016, with a Canon 5DSR full-frame camera equipped with a Canon 70-200 f2.8L IS II USM telephoto lens.

A Westcoast Air (C-FGQH) Twin Otter floatplane (DHC-6) was about to land in the Vancouver Harbour. It is obvious that adjusting the shutter speed to 1/1200 would have given enough speed to obtain a clear image. But this would have taken away any movement sensation by freezing the propellers and background.

The shutter speed had to be slow enough to allow the rotation of propellers. It is clear that an aircraft’s propeller rotates more slowly on final for landing than during take-off. So the camera had to be adjusted for a shutter speed varying between 1/40 and 1/125.

A slower shutter speed increases the risk of getting a blurred photo, especially when the photograph must move with the camera to obtain the desired effect of movement. The fact that a telephoto lens is used also increases the possibility of a blurred picture. It is thus imperative to activate the stabilizer and horizontal panning function of the telephoto lens.

To obtain a background without any precise details, the camera is panning and follows exactly the aircraft’s movement. This requires a progressive acceleration of the panning, according to the aircraft’s position from the photographer.

When the Twin Otter gets closer, things get a bit more complicated as everything speeds up. It is necessary to already have positioned the feet in the appropriate direction in order to avoid a major switch in the body’s posture. The slightest useless or brisk movement would immediately be visible on the photo.

With a bit of practice, a photographer will achieve success by respecting the following elements: a shutter speed between 1/40 and 1/125, an appropriate position of the feet, no brisk movement while pivoting and a progressive acceleration of the body’s rotation aligned with the aircraft’s speed. A slower shutter speed will enhance the aircraft movement. But expect more blurred pictures when working with speeds between 1/40 and 1/60.

A last detail: as soon as the aircraft’s floats touch the water, the deceleration starts. The photographer’s pivoting speed must immediately slow down otherwise the photo will be blurred.

Viking’s Twin Otter Series 400 in Victoria, British Columbia

Knowing I would spend some time in Victoria in 2016, I planned a visit of the Viking Air Ltd installations, the Canadian company who now builds the famous Twin Otter Series 400. This company is unknown from a majority of Canadians since its production is essentially exported. Out of one hundred aircrafts produced so far, only two were bought by a Canadian company. Viking also offers maintenance service for the Twin Otter Series 100 to 300 in activity around the world.

In the beginning of 2016, Bombardier and Viking sealed a commercial deal that now makes Viking the new owner of the patents and designs for the CL-215 and CL-415 water bombers. Viking not only services the existing Twin Otters but is evaluating the possibility of restarting the production of the CL-415 water bombers. All is resting on the demand. But with more extreme meteorological conditions fueling a growing number of major forest fires, one can expect that within the next few years Viking will reactivate the production.

In Victoria, a Twin Otter Series 400 on floats built by Viking has been bought by Reignwood Air. It is ready for delivery to China (2016).

With the on-going regulatory changes actually taking place in China, Viking is confident to see an increase in its orders for the Twin Otter Series 400 on floats. The company will receive, at their Victoria installations in 2016, the first flight simulator essentially dedicated to training pilots on the Twin Otter on floats.

For now, Russia is Viking’s most important customer despite the ups and downs linked to the political crisis between that country and Ukraine combined with a ruble devaluation that have forced a slowdown in the production of aircrafts destined to Russian companies. With the recent stabilization in the political situation, Viking has been able to hire back numerous workers which now brings the count to at least 350 employees, if my memory does not fail me.

Nowadays, most Canadians ignore that a Canadian company has restarted the production of the Twin Otters and is evaluating the possibility of also relaunching the production of the CL-415 water bombers. In the meantime, some CL-215s recently acquired by Viking will possibly be transformed into the more powerful CL-415 version. The only thing now missing for Viking is an important order from a Canadian company: that would make its name as well-known as Bombardier or De Havilland.
