Sharpening in Photoshop
How to Sharpen your Photos in Photoshop CS6?
Sharp photos? Just a basic must and while even low-end digital cameras let most anyone take a clear picture, sharpness is yet another issue. The difference between pros and amateurs is threefold:
First, a Pro would always try to use a tripod and use quality equipment, namely quality glass; in Photography it’s as elsewhere, you get what you pay for.
Second, a Pro would use a few tricks to get most out of his equipment.
Third: many a Pro would pull his pictures through a Program such as Photoshop to improve sharpness.
Quick Tips for Sharpening in Photoshop
In Photoshop the sharpening tool is called ‘Unsharp Mask Filter’. Just forget about this misleading name and retain ‘unsharp’ in Photoshop sharpens your photos :-).
Without going into technicalities, here are some basic values which may serve as a start for your sharpening:
Portraits: Amount 150%, Radius 1, Threshold 10
Street Photography, Urban, Travel: Amount 70%, Radius 3, Threshold 3
For General use: Amount: 90%, Radius 1, Threshold 5
Professional Sharpening on Photoshop CS6
The main problem with sharpening are color artifacts and halos which occur when we do heavy sharpening. For this reason we will sharpen just the detail not the color of the picture.
1. Go Image > Mode > Select Lab Color
2. On your Layer Stack select Chanel view > then select the Lightness Channel
3. Apply the above defined Unsharp Mask Filter twice. If this is too much sharpening, then go to Edit > Fade Unsharp Mask > lower the opacity to taste.
4. Go back to Image > Mode > select RGB Color.
Done :-).
