Photoshop Tutorials - correcting chromatic aberrations (purple fringing)  

From time-to-time you may come across "Purple Fringing" in your photos from digital cameras. This normally occurs when an area in the digital photo is overexposed, contrasty and often when a suject is lit from behind. This is the most common type of 'Chromatic Aberrations'. There are other types of "colour fringing" too, such as green and red fringing.
Mostly consumer prosumer compact digital cameras have this issue, however digital SLRs have been seen to suffer from this, too.
Editing the photo using a photo editing software, such as Adobe Photoshop, Adobe Elements or Paintshop, can reduce or remove this purple fringing effect, so here's a quick fix using Photoshop to correct this type of chromatic aberration.

1. Open photo in Photoshop.
2. Zoom the image to 100%.
3. Choose Image --> Adjust --> Hue/Saturation.



5. Select 'Magentas' from the Edit down menu.
6. Change the Saturation to -80 and the Lightness to +16. This is an approximation so you may want to change these settings depending on the digital photo.
7. Push the color slider (bottom) either right or left. Once you see that the chromatic aberration has been cleared, click on OK.
8. Save the photo
