I’m always looking for good stock images to use in my photoshop composites. I find them online, or use the awesome Texture Store. Or I make my own. But sometimes its impossible to find the right image that fits your idea.
And if you do find the right image, it’s at the wrong angle or too small, or not lighted the way you want to. So you’ll just end up with a crappy composite, or spending hours of time to get it right.
A while ago I was preparing a workshop and looking into the possibility to teach everyone about using photoshop’s built in 3D options. Photoshop has been developing integration with 3D for a while and you can even get as far as prepare a file for 3D printing now.
