The DVD I recently ordered contains 48 digital backgrounds at 300dpi and can be used in Photoshop. I haven't checked the tutorial with which it comes but I'm sure it can be used on most available platforms and with most professional software.
I was just fooling around with a picture of Tiny Kitty and this is the frightening result.
Don't worry, you won't be seeing too much of this from me. This disc has tremendous potential.
In my hands it has tremendous potential for pain.
