For my first few years of using Photoshop, all I ever done was Crop, Resize, add Text and maybe play with Filters. All the time I could see all these other menu options for doing stuff and I knew you could do way more with it. However, most people beginning Photoshop will only need the basics and I hope to cover most of them here.
I’m an experienced Photoshop user (since 2000) and gained my official Expert certificate from Adobe in 2014. One of only 8 in Ireland at the time.
