HOW DO i LEARN PHOTOSHOP

Question

how do I leaRN TO PHOTOSHOP

Answer 1

Along with the suggestions for some good tutorials, much of the answer will depend on how YOU learn best.
Some learn better with reading.
Some learn better with doing.
Some learn better by watching others do it.
I am a combo of 1 & 2, with emphasis on 1. My wife is a combo of 2 & 3, with emphasis on 3. It just depends on the person.
One good resource for 1 & 2 is the Adobe Classroom in a Book PS CS __ , by Adobe Press. It has both the reading and then the doing, in a series of exercises. Those exercises are representative of real-world operations, and usually explore the multiple ways that PS allows the user to the same thing - the same end result is shown with several methods. As soon as CiaB comes out for my Adobe programs, I pick up a copy, and work through the exercises, while reading.
Considering the popularity of tutorials, I think that # 3 is a more common learning path nowadays.
Which ever path you choose, remember, you will never know everything about Photoshop. I've been using it commercially for almost two decades, and learn something new in these forums, almost every day.
Good luck and happy learning.
