Flatbed scanning tip
If you have a stack of favorite old prints, you may want to scan them for your digital archive. Here are some common-sense tips that will help you scan with your flatbed scanner more efficiently.
Clean the surface
Invisible dust? No way! Although I cleaned my scanner's glass scanning surface, a few hairs and spots got through in this street photo that I shot in New York in the late ‘70s. Can't see the dust on your monitor at this small size? They are there…and will show up clearly on your prints! Photo © 1978 Mason Resnick
Inspect the scan
Full size tells all: At 100 percent, you can see hair and spots in this detail section.
Use a global spot removal filter
If at first you don't succeed... At first blush, Photoshop’s dust and scratches filter is ineffective in removing blemishes and changes the grain structure.
...Play with the sliders! But once you play with the Radius and Threshold sliders you can fine-tune sharpness and get rid of most of the dust.
Use the healing tool
Cleaned up: It took about a minute following the above procedure to produce a clean imaage--and there was a lot of dust!
Use the cloning tool
The right tools: The healing tool (top) and cloning tool (bottom) will whisk away your problems...if you have the time!
