So when you’re taking pictures a darkish topic on a white background, change the background. Try to shoot your topic on a background that’s much like its important colours. Instead of taking pictures a purple flower in opposition to a vivid white background, shoot in opposition to a inexperienced background. And chromatic aberration will immediately develop into much less of a problem.

Another means that everybody can decrease chromatic aberration is by stopping down. That is, use an aperture a cease or two past your lens’s most. If you’re working with an f/2.8 lens, cease right down to f/4 or f/5.6. Numerous the colour fringing will disappear.

You may attempt putting your topic towards the middle of the body. One kind of coloration fringing (lateral chromatic aberration) solely happens on the edges of the body. By positioning your important topic on the heart of the picture, you scale back the impact that CA has in your photograph.
But typically,
chromatic aberration will get out of hand, and there’s nothing you are able to do about it
within the subject.
