Adobe Photoshop is one of the programs I spend most time with and was also the hardest for me to get into. Back then I still used Microsoft Paint and slowly into Paint Shop Pro, but I ended up using Photoshop after some time and it has been my goto program for all graphic ever since.
Today I use it for reparing old photos and editing my photographs I take with my Camera, im not a master yet, but it is on the list of things I want to be. I always try to get better at using my programs.
I started when Adobe Photoshop 5.5 was out and today I use the CC packet from Adobe.
