Large format cameras are easily the most technical of their kind, but they reward the photographer with extra capabilities and stunning resolution. This video takes another look at some of those capabilities.
Coming to you from Ben Horne, this video is an additional look at the mechanics of a large format camera. In his previous video, he discussed rear tilt, which allows a photographer to enlarge or shrink foreground and background elements. In this video, he's talking about front tilt, which allows the photographer to change the angle the focal plane makes with respect to the film plane. This is a more well-known movement, as it's the same thing a tilt-shift lens does. The benefit of tilting the focal plane is the increased depth of field achieved without changing the aperture, which allows one to maintain a certain shutter speed and aperture combination or avoid using ultra-narrow apertures that could introduce noticeable diffraction. For example, in the waterfall photo, he likely wanted a certain shutter speed for the water blur and chose an aperture for the amount of available light and film speed, then used front tilt to increase his depth of field. As an aside, if you want a laugh at how truly big large format is, notice how when Horne mentioned his 150mm lens, he said that it's his wide angle lens.
