Chromatic Abberations, more commonly known as purple fringing can be found using any camera from film to digital. In some cameras it seems to be more of a problem than in others, especially the newer 8MP cameras. You will usually notice it on bright colors and on highly reflective surfaces like metal objects. It appears as a purple, blue or green outline around the edges. There are several photoshop plugins that are supposed to take care of this problem very easily. I've tried a couple of them and sometimes they work and sometimes they don't. I found out about a fairly simple way to get rid of the purple fringing in your photos. First, load your photo into photoshop or elements 2. To me it is easier to fix the purple fringing before you do anything else to the photo, but you can do other things before you do this. After you load your photo, click on Image>Adjustments>Hue/Saturation. The Hue/Saturation window will pop up and at the top you will see Edit with Master beside it. Scroll down and change Master to Magentas. Now as you hold your curser over your photo, you will notice that it has turned into the eyedropper tool. Find a spot on your photo that has the purple fringing. I usually start out by clicking on the darkest shade of purple I can find. Now you will go to the Hue/Saturation window and you will slide the Saturation and lightness bars to the left to around -50 then click okay. If you still notice some purple fringing, repeat this process. I have noticed that on some purple fringing you actually have to go to the + side. So, just play around and see which way works best. I also want to mention that if you have anything in your photo that is supposed to be purple, it will change that as well. So, when you are done correcting for the purple fringing, click on the history brush and then go to the history pallet and click on the box next to the action you last performed before doing any correction for the purple fringing. Go over the areas that you want purple and the colors will return to normal.
