CS5

My background in filmmaking and animating keeps my focus on any editing and animation tools that become available. I've used Photoshop over the years to design textures for 3D objects or basic photo touchups required for the final video project. And although I have a collection of decent SLR cameras, still photography is more of a hobby for me, so I've limited my use with Photoshop to the video/animating worlds. Thus when Photoshop CS4 Extended came out a couple of years ago, I was already familiar with the basic animating tools included that may have eluded the amateur or pro photographer.
