The ArtFx team is passionate about digital photography and closely follows the evolutions of cameras. Below, Gilbert Kiner, the school’s director, shares his experiences of using the Canon TS-E 24mm perspective control lens on a Canon EOS 5D Mark II camera over the course of a few weeks.
The shifting technique
Modeled on the principle of the old photographic chamber, the perspective control lens allows the photographer to shift the perspective horizontally or vertically. Like this, the lens can capture a larger image circle while keeping the body of the camera completely parallel with photographed subject. This prevents the parallel lines of a photographed subject like a tall monument, for example, from converging near the top.
The various applications and extraordinary images
The Canon TS-E 24mm is equipped with two types of lens adjustment options.
The first allows the shifting of the optical axis from the sensor plane. The initial goal of this process is to compete with photography studios in the alteration of perspectives. When I am at the foot of a building, I incline the camera up towards the top of building. The facade of the building is no longer parallel with the surface of my lens and the low-angle position causes the lines of the building to converge at the top. By shifting the perspective of my lens, I am able to correct this phenomenon. The building retains its rectangular form in photograph. This technique delights Matte Painters, Architects and Illustration Photographers.
The second type of adjustment provided by Canon allows one to manipulate the plane of sharp focus. This means that the net area of an image is no longer parallel to the sensor. This procedure creates extraordinary images in which one sees the image pass from a sharp focus around the subject to a significantly blurred background, no longer controlled by the depth of field, but by the manipulation of the settings. Of course, adjusting the depth of field will also change the degree of blur in the image.
It also goes without saying that one can combine both types of adjustments in order to obtain very unique images.
An additional advantage, no less important than the others, of perspective shifting is that it allows a photographer to take a picture of a reflective surface without appearing in the image. The shift control lets the photographer stand outside of the reflective area while positioning the lens so the image looks like it was shot straight on. That annoying mirror effect is thereby eliminated. I recommend trying this!
Trendy and doable effects: a little and a lot…
Currently, this type of lens is often used in the creation of music videos, commercials, etc. The effect is very aesthetically pleasing and more illustrative, which significantly pleases directors and cinematographers.
Personally, I prefer the more subtle effects. Therefore, I try to use the ‘more refined’ settings. The result of these adjustments is not always obvious when looking through the viewfinder or on the screen of the device. Often, it isn’t until later, by looking at the captured image on the computer screen, that you can get a true idea of the picture. This is why I often take several shots with different settings to increase my chances of success.
