I’ve created a very short Photoshop demo on adding 3D text to a photograph, then using that photo as part of the material for the 3D object. This video is going to be submitted to the Next Photoshop Evangelist event hosted by Adobe and NAPP. I hope to get another video or two up soon, but Vimeo limits the number of HD uploads you can make in a week with a free account. So the others will be in standard resolution.
Go check out the other entries – there is some good info there, and I hope to see many more entries in the next week. The deadline for uploads is August 24th. If you want to get in on this, put together a 2-minute video and sign up!
