[quote name='jer7583']Not to be a douchebag or anything, but Photoshop isn't a true vector program. It creates raster images using bitmaps. Illustrator is a true vector based program because everything created with it (in vector mode of course) is based on mathematical formulas for curves, lines, etc. As such, multiplying (or dividing) the size doesn't affect the quality of vector images, which is what makes them so ideal for commerical applications. Billboard or cardboard box, vector images all come out the same.
I love illustrator. Took a class for it last semester. Makes such clean looking work. Illustrator + Wacom tablets = digital artist's dream.
and those example vector drawings in the link posted before are simply stunning. I attempted a photorealistic gradient mesh of Ed Norton in a pose from fight club, and I thought it looked pretty good, but this stuff is unreal. The Kiera Knightley one is awesome. Must have taken a long long time to get all the shadings right and vertexes placed perfectly. It's so impressive to someone who understands what it takes to create such a great gradient mesh.
The only thing is that most(all) of those were probably created using high resolution photos as "reference" meaning used to create oulines and vertexes. I'd like to see what people can do from scratch. (I think that the retro styled ones of bert monroy may be more original)[/QUOTE]
I knew someone would bring that up.
Photoshop is a truly raster making program. However, assuming the OP is a newbie, I didn't go into the real difference between raster and vector because in Photoshop the pen tool does create images that can be infinitely big or small without quality loss (pre-raster shapes, of course). I'm sure he won't be using math equations.
