What to do! You have taken a lovely photo, only to take it home and discover this purplish haze around the edges of the subject??
The most common cause of purple fringing is low light with high-contrast boundary areas in an image. So in the case of my example above, I took a photo of a reflective surface on a sunny day with the sun shining behind it.
Oh woe is me! Well.. never fear.. there is a way to fix this photo using Photoshop, I am going to show you the way that was easiest for me, of course there are a number of ways to do this… but I found this method to be the easiest to remember and most effective!
Step 1: Open up the image in Photoshop
Step 2: Using the toolbar, select image>adjustments>hue/saturation. A small hue/saturation box should appear on the screen.
Step 3: In the drop down menu that says Master, select Magentas. Now move the saturation slider down to -50, and move the lightness slider down to -50.
Step 4:If needed repeat steps 2 and 3
Now the Purple Fringing is gone.. Hoorah!!
