Hello,

I scan images often and would like to set a threshold that would
convert the pixels below the threshold to white (0) automatically in
an image. Is this possible? Do I need a filter or need to develop a
script?

Thanks,

André Luiz

Hello,

Thanks for the reply. From your words I suppose I´ll have to scan
again the images, correct, and I would not like this because there are
far too many of them. I´d like to do it automatically in Photoshop
instead is possible.

Sincerely,

André Luiz
