I got my new computer this week, and I decided to sign up for a trial of Adobe Creative Cloud. I've been wanting to see for myself where the differences are between Paint Shop Pro and Photoshop and which performs better at the things I do. So far, my experiences have been roughly even.
I used the same methods and similar materials to create the backgrounds below:
The first was made in PSP with one of my favorite methods. The second, which I do like, was an attempt to duplicate the technique in PS. It's a cool background, but really not what I had been trying to do.
Then there are these:
For the first one, I was just experimenting with Photoshop to see what I could come up with and how the various settings work. The second one is a totally unsuccessful attempt to duplicate it in Paint Shop Pro with the same methods and as close as I could get to the same materials. I like it, but it's definitely not the effect I was trying to achieve. Photoshop's blend mode options and brush settings are a lot more varied. (I won't say "better" because I haven't used it enough to make a qualified judgement, but there are just a lot more options to work with.)
As a side note, I'm sure could re-create it if I took more time and did it another way, but I was interested in seeing what the result would be if I did everything the same way.
