A member of the community over at Core77, yo, has written a concise but informative tutorial on how to transfer a quick product sketch into a loose Photoshop rendering. By his count, the sketch should take about 10 minutes, and the Photoshop work should take about 20 minutes. Half an hour for a relatively nice looking piece, most definitely worth a look! This tutorial might be considered a bit beginner-ish for some of you readers.
