I use the XNALara program, which is posted online for free, although there are newer versions of that program also posted free online. The newer version is called XPS-(XNALara Posing Studio). Other people here on DA and some other related groups create 3-D models-(people, objects, vehicle, weapons, rooms, etc), for specific use in that program. You merely download for free, then install them into the program, which allows you to pose them in a 3-D workspace. It's pretty easy to use. I had no 3-D modelling experience at all before I discovered this program and learned how to create scenes. You'll notice here on DA anyone using that program & using other people's models for it always credit the original model's creators, myself included. I pose the scene in XNALara, then use a screen-capture program to take a 2-D "snapshot" of the scene on my monitor, then import that picture into my PhotoShop Elements-9 program, where I can then edit the scene to my liking-(adjust color, flesh-tone, body parts, sharpness, brightness, etc). Trust me, I'm no expert at all when it comes to this, and I haven't learned how to create my own 3-D models as of yet, but working with this program make it pretty easy!!!
