What are the main PS technologies that need to be mastered in post-processing of photography?

PS is a wide-ranging technology, and the application scope of PS software is different for everyone!

You mentioned the word photography above, photography should first highlight the photography level, followed by PS assistance!

For the initial PS tool operation, you can only find a friend who knows PS to watch him do it and let him teach you the basic operation of PS! The function of each tool!

A friend said earlier that it is mainly a pivot diagram, and the pivot diagram is only a function of PS!

If you want to do a good job in PS, you should first start by coloring photos, learn to look at more photos, find a photo you like, and observe where the colors look good. Find the reason! A good PS master is not because he knows a lot of PS stunts! It is his examination of beauty, where the color is heavy, where the color is light, and what color and tone can have a beautiful effect! Wait, I know everything! That's the real PS master! ! !

As for the fulcrum plus background, hand-painted and multi-picture design together! That's just a train car!

Learn to color first, and have a good feeling for beauty! That's the front of the train! !

I wish you an early success! ! !
