Avoiding Purple Fringing

This week, because I used a very wide aperture (f1.7, f2.5) and the light is very bright right now in the day time, some of the photos I took got an unattractive purple fringing. I just noticed it after several photos and got a little mad with myself because I wasn’t paying enough attention.

Purple Fringing

Purple fringing is that sort of light “specter” you get on the edges of photographed subjects where the bright light and the shadows meet.

You can avoid that unappealing aberration if you use a narrow aperture when the light is very bright. It will give you longer depth of field (your background is going to be more in focus than with a wide aperture) but it will give you a crisper image with less chromatic aberrations around the edges.

To do that turn you camera to Aperture Priority Mode (turn your mode dial to “A”) and set the aperture (f value) to f11 or smaller (the higher the f value, the narrower the aperture).
