I got the new Nikon D7200 today and took a few practice shots. I posted them in the Photo Gallery section if you're interested. No White Balance problems with the new camera. Very exciting!

In reviewing all the helpful data, I was unable to fix what I believe is chromatic aberration in this photo. I did find the chromatic aberration sliders in PS>Filters>Lens Correction>Custom, but when I tried moving the blue slider there was no result. I know this image has lots of problems, but I'm just learning, so I'll tackle one demon at a time. This image also suffers from a beginner's error....I forgot to set my Canon SX60HS to JPEG+RAW. Oops. But according to the literature, I should be able to adjust the CA on the JPEG to get rid of the blue line under the left wing. Any ideas?

Sorry, but this does not appear to be chromatic aberration. This appears to be white feathers in shadow picking up the blue of both the water and sky. There is a similar spot of blue in the crook of the right wing.

It looks to me that the sun is low in the sky to the right of the bird. It is shining on the left shoulder, the underside of the right wing, and the underside of the tail, which would put the upper side of the tail in shadow {'shade' was a poor choice of words} - the bird is tilted slightly to the left.

Ok I had a go :)


You had a very successful go at it. This looks like what I would expect without so much blue from the water and sky lighting (probably mostly sky lighting).

I did it pretty much as i said I would used a local adjustment brush with automask and a 4 stop burn on the bird and then removed that burn rebalanced the white balance and a little highlight and shadow adjustment. Then a slight tweak on global white balance trying to keep the water a reasonable shade, fairly close to the d7200 photos the OP posted in the gallery, still a touch of blue in the tail but about the best I could manage with a jpeg.

Thanks for all this useful information. I'm going to try to replicate it. Meanwhile, the D7200 arrived today. I went to the same spot and took a few similar pics. Amazing results. The lighting was a lot different, but nevertheless, the difference between the two cameras is stark to me. The last pic is just for fun ;-)

I think a whiter tail might make it seem too processed since there is some skylighting and the tail is in shadow. I also know without a reference point like we had, people might not notice. But I side with your decision to leave the remaining tint since that makes it seem more real and natural. Also I like how the water came out not as deep blue and more what I would perceive as natural.

If it's bad, I have a little process that doesn't take long.
Duplicate layer - Go to Gaussian Blur to about 15 - Put the blending mode to Color, Make a layer mask and paint out the CA.
