I want to 'mastered' Photoshop skill. So what is the best way to start? Googling online or just attend the real class?
Rezadnil, I self taught myself Photoshop and then got into Photoshop classes in high school and college that improved my skill further. I started out with online Photoshop tutorials and then started reading articles about Photoshop on popular design blogs. I'd suggest you do the same. I'd also advise taking some graphic design classes in whatever school you're going to, if you're currently attending school. I definitely learned a lot in the classes I took, and having a professor that is more like a mentor can benefit you in ways you couldn't imagine. I'd also recommend that you check out the Lynda.com training on Photoshop. It's $25 a month, but I get it free through my college. Anyway, it has a lot of awesome video tutorials on Photoshop, from the most basic features to the most advanced. It really breaks it down bit by bit and shows you everything you need to know. It's helped me a lot in my design career and I know it can help you out too.
Googling online would be convenient and economical for. there are lots of sites which give free Photoshop lessons.
it's sort of a parody, but you'll learn A LOT from "you suck at photoshop" either google it or go to mydamnchannel
You need creative mind to master photoshop, because photoshop is only a software or a tool to help professional and talented people make their life more easier. When you already have photoshop software in your computer, the first thing to do is to read the help tutorial basics so you will know the easiest part. I know that reading the tutorial manual is boring, but it will surely benefit you. Every masters do the basics!
