Many Poser users never change the Poser lens focal length from its 38mm default setting. By ignoring this basic option they choose to give up substantial creative control. This illustrated article will show you the effects of different lens focal lengths and when and how to use them. Only models included with Poser are used so that you may freely duplicate and experiment with them.
If you have ever used the Group Edit tool in Poser, you have seen the Create Perspective UVs button, but probably had no idea what it was for.
Even if you pressed it out of curiosity, it likely had no noticeable effect unless certain criteria were already met.
This tutorial will step you through creating a Perspective UV projection on a box, and will go on to explain how to apply this tool to the creation of working lenses.
