Hi

I am new to PP,just started taking photos in RAW and JPEG,started to play around,in PP

I am not very good with computers,Is there a book or some document that can help me learn PP??

I am trying to figure out this 'unsharpen mask',-'sharpen mask',and really not sure what it all means or how to do it.

I hope there may be one of those 'Dummies guide to.....' books or similar.

thanks FB
