Doing a photo shoot can be tricky. Setting up the location, finding the props, getting the lighting right, etc, can be time consuming and sometimes expensive. If you want a specific picture of an object in a particular setting, you usually need to get that object, set it up, light it, and photograph it.
So I'm finding a new beta from Adobe quite interesting. Called Project Felix, it lets you assemble 3D objects and render them into a Photoshop file. I've been having a play with it and it's pretty simple to use, and has lots of potential. Just drag objects from the library into the canvas, use the move, zoom and rotate tools to assemble the scene just the way you like it, then render as a finished image. Export that image into Photoshop as a PSD file and keep working on it. Lots of possibilities.
Check the minimum system requirements though... the rendering process can be pretty computationally intensive. Rendering even a relatively simple image on my MacBook Air with an i7 processor took quite a l-o-n-g time. Still, it got there in the end.
