Do you know about the NIK collection of filters? They are free and you can read more about it HERE. Since they are free, why not download them and play around with the multiple presets and settings and show us what you can do with them. Show a before and after of your photos in the thread below.
Here are my before and after images. I used the Defin2, colour effect and sharpener raw to get the final effect. Really pleased with the result as it was scanned photo taken many years ago so it was in a fairly bad condition. Can’t believe how blond and blue eyed my little boy was then as his hair went quite dark as he got older. My daughter, who is the one digging, has the same colour hair now as then. Where has all the time gone.
