I'm wondering if any of you have used your computer and photoshop to make dodge and burn masks to aid in black and white printing? If so on what medium do you print your masks? How is it done? I'm a traditional photog with ZERO photoshop skills but I am considering getting a computer soon and would like to know...do you use a litho screen in p-shop? or a particular tool, or shades of gray? Are there any books or articles that I should read? Thanks in advance friends!
