Tip 4: Source Your Objects
The enhancements in Photoshop's 3D object handling often make it easier to use a 3D model than to search for a clip-art image. If you need a small element for your montage (such as a coffeepot, a chair, or a pen), a 3D model will be easier to work with than trying to find a photograph captured from exactly the right angle.
The Internet offers many sources of 3D objects. One of the largest is archive3d.net, a huge repository of 3D models available for free download (see Figure 4). However, many of the models are in formats that will break apart when imported into Photoshop, and the search engine is poorly constructed.
If you use a lot of 3D objects, consider buying a library. The best I've found is The Archive from Digimation, a vast collection of models that all import perfectly into Photoshop. The Archive costs $599 for over 16,000 models, and it includes a speedy search engine that lets you find exactly the right model.
