Vignetting, or the black halo you see around the edges of a picture can be a problem with Canon lenses. This picture that contains vignetting was taken with a Canon L series 24-105 mm lens. You’d think at $1000 the lens wouldn’t do that, but it does.
In this picture I went with it. Why not? The vignetting was so severe that Photoshop Raw had trouble getting rid of it all. Then I decided to make the effect really stand out by moving the vignetting slider to 100. I did this because the effect matched the bright red building in the middle of the picture.
So…I broke every rule in the book. Well, not every rule. The picture, aside from the vignetting, is exposed well; there are neither blown highlights nor dark shadows in it.by
