Magenta and Cyan edges to parts of an Image
May 1, 2013 12:37:41 #
I have been working on an image for printing and near the end of the PP I noticed that on a part of the image (an open window)near the top left where the edge of the stone touches the sky there is a magenta line. On the Opposite side of this window there is a Cyan edge to the stone. In the centre of the image I do not seem to have this problem. On the Right side it reappears. At first I thought it was due to what I had done in PP, but on checking the RAW image I find that it is there, but simply emphasised by the PP. The image was taken with a D90 and an 18-105 Zoom. I have uploaded the JPEG image and I hope all the info is still attached. Any thoughts on why I have this problem, which ruins the image for printing.

Look up chromatic abberation, or CA. It's a lens thing, more prominent in less expensive lenses. Sometimes Photoshop can corrrect this.
Nice shot, worthy of fixing.

Google "Chromatic Aberration".
The more expensive the lens the less you get. (Typically)

No worries. (And I'm on an iPhone)
At least we followed up with the same right answers.

I find that Lightroom4 works great for correcting lens distortion and chromatic aberration with just 2 clicks. As previously stated, this is what you are dealing with.

I ran it through CameraRaw in PhotoShop CS6 and got rid of 99% of it they do not have a profile for the 18mm-105mm so used the 18mm-200mm and it did a decent job

Many thanks for all your responses. Chromatic Aberration! I will now chase it down and see what I can do!

They come to my house to do that - no charge at all. Another benefit of living in NY. If the damage is smaller than a dollar bill, they repair it. If it's larger or dangerous, they replace it.

It would have been $25 more for that service and I needed to get away for lunch.
