For a digital imaging 101 topic, it is surprising to see how much chromatic aberration makes it onto the printed page. You can pretty much look at any publication from Sports Illustrated to your regional lifestyle magazine and see a heavy dose of chromatic aberration in a fair amount of the images. It looks really bad and amateurish! So please I am urging you to have higher quality control standards in regards to professional photography. I am sick of seeing chromatic aberration in reputable publications, and even in some photography galleries.
If you don’t know what chromatic aberration is, it is the red, blue and/or purple “bleeding” on the high contrast edges of a photo. Good lenses have less of this but digital cameras seem to play a role in this as well. Usually it can be eliminated in Adobe Camera RAW. On really poor lenses however, minimizing the amount of CA is usually the best you can do. If ACR doesn’t work for you, then you can try PT Lens which only costs $15, or some other 3rd party software to fix your lens distortions.
Sometimes you can’t avoid it all together but if a big purple halo is in places that obviously shouldn’t have any purple then you’ve got to ask yourself are you doing all that you can to produce the best file possible? Attention to details such as this should separate a professional photographer from a hobbyist or snapshooter but unfortunately that is not always the case.
