After about one year of working in A4, I have done an A3 sketch today. What a relief! I have trained myself to work in A4 for technical reasons, but its difficult for me (I need special glasses). Plus I'm just better in larger formats.
What's your experience with size? Did anyone buy an A3 scanner? Can you recommand it, or do you have other ideas about doing illustration in larger sizes and getting it inside the computer somehow? Is making a photo really an option?
