Have you ever tried a YouTube tutorial that didn’t turn out the way the instructor said it would?
I’m not saying it is always the instructor’s fault. I think there are 2 causes when a tutorial doesn’t end up like it should.
First, the viewer not putting in the requisite time to understand the material and skipping steps. If you want amazing, professional results in a program like Photoshop, you have to learn the basics.
Second, over simplification on the part of the instructor! I’ve watched so many ‘tutorials’ that do nothing other than let you watch while someone does something and in no way explains the process or why they chose to use the tools they did or any other part of it.
The key to success is practice. No one tutorial is going to make you an expert. They say it takes 1000 hours to become an expert.
