Unsharp Mask in Photoshop
Sharpening digital images is crucial step in getting your photos ready for print, and can also greatly improve the quality of photos for online presentation.
"Unsharp Mask" is a filter found in Photoshop and other graphic programs. In Photoshop, you can find Unsharp Mask in: Filters > Sharpen > Unsharp Mask.
There are 3 settings under this filter:
For portraits, an increased setting of around 6 would be best (if you don't want those pores and pimples being sharpened for you viewing pleasure.)
So, settings of
125 - 1.5 - 3 (for print)
are basic starting points to start tweaking from.
When sharpening for print, the on-screen preview of the photo will usually look over-sharpened; even though when printed the amount seems just right. Tests-runs, experience over time, and talking to your printer will help you make sharpening decisions for print.
Sharpening should be the last, or one of last edits you perform on your image.
Be careful when sharpening photographs with flesh, over-sharpened skin can look icky.
