This is a bad example, but it shows a real view solidworks rendering (in this case, a nozzle) next to a picture I took of an actual existing part. In this particular case, i took the picture to highlight the fact that the drawings do not represent the final product (as you can see there are some profile differences). But none-the-less you can see that, without using any fancy "photoworks" or "photoview 360" package, you can still get fairly decent renders using standard screen shots from solidworks. All i did was turn realview graphics on and got rid of my black tangency lines.
