Chromatic aberration

Chromatic aberration appears in photos as "fringes" of color along boundaries that separate dark and bright parts of the image and can be most annoying.
Even with Canon L glass and a reasonably high end camera, I'm still faced with it in certain situations - with trees against pale skies, for example, or the edges of a building against a white sky, or blue sky with clouds.
There are times when even my software (Photoshop CS5) can't completely eradicate it, so I've figured out a fix which works nicely to address this.
With your image open in PS, select the Lasso tool and draw a selection around the offending area. Then, go to the Hue/Saturation adjustments panel, and instead of Master, click on the drop down arrow and choose Cyans...then pull the saturation slider to the left until your cyan fringe disappears. Repeat with the Magentas too and this should deal with the problem.
I've also used this method for purple fringing but be aware it won't work well if you have blue sky in your image, as pulling the Blues or Cyans sliders will also affect the color of the sky.

@ Aneese - sorry, yes, I should have mentioned I work with adjustment layers. @ Melissa - yes, I think you'll find you need to remove any elements on tombstones to avoid rejections. I've got some tombstone images and I just cloned out the information on them. It was a bit time consuming though ;o)

Nice tip. You can do the same thing in layers and use a layer to paint in or out the areas that need to be changed. The advantage of this is that it is non distructive to the original picture and one can always go back to the original image

Hi Tamara- I like how creative your photos are. I see you have done a religious collection. I am beginning to do a series of grave/church photos myself and you may be able to answer my question. On some of the headstone shots I have the names showing, do you know if this is allowable? Or should I try to hide the names? Please let me know what you think? Cheers from Melissa, NZ

It depends on the image, Adeliepenguin...I might try a radius of 2 or so but it might mean you have to experiment a bit. I'm quite certain I've had images where my selections aren't feathered at all, but it depends on what other elements are in the image.

Thanks for sharing! I am curious, do you feather the edges of the selection so they blend into the rest of the image?
