I want to create a logo that can be used for letterhead, the web, etc. Any recommendations for a canvas size for the master image? Once the logo is created, how would I go about creating a favicon from it? In wikipedia, there is a lot about sizes and file types, but in general, how do I reduce (or export) the size of an image to something much smaller, and a specific size like 16x16 pixels? My logo is made up of OG lines and a circle. If I group the objects and then reduce the size in OG (by shift-dragging a corner), the lines stay the same thickness.

I have Pro 5 (and Pro 6 which I'll be able to use shortly after I get my 10.8 system up and running). thanks
