A couple of months ago I was playing with my camera and a magnifying glass and I noticed that this glass produced a very soft chromatic aberration. Here's an example:
(Here is the full size, 18mp image)
Altough the effect was pretty cool, I couldn't focus too far from the lens. Here's another example, but with an object to a few meters farther.
Maybe at this resolution the dog seems to be focused, but in the full picture you can notice that it isn't. Also the CA effect isn't that pronounced as in the first picture. (For pixel peepers, here's the full size image)
So, is there an easy way to produce chromatic aberration? I know that there are some lensbaby optics that can do that, but I'm looking for something like DIY.
Just a random thought: Could I emulate it by shifting the color layers of the image? I mean, the image is composed by three diferent layers of color, if i offset them a few pixels, will that produce some CA?
I'm pretty sure that the colors of the photo will go nuts, but maybe there's a related solution.
I'm offering 300 sexy points of my own reputation for a cool, nice and DIY solution for this. Go go go!

Well, this wasn't easy. Coneslayer gave me the best answer, but Autopulated gave me the most easy, direct and (not-so) DIY solution. So:
1) I've accepted Coneslayer answer
2) I've gave the 300 sexy points to Autopulated
Thanks for your help, you both are awesome!
