I'm interested in some digital photos of Japanese prints but I need them to be high quality in order to print it in big dimension ( 120 x 90cm). I am ready to pay if it's needed. Is there any place on the internet that can satisfy this demand?
I would try a couple of the "stockphoto" web sites they normally have what you need.
I second checking stock photo sites.
If you need some quality photos of Japan in general, I'm a freelance photog in Tokyo. I'd be keen on any commision you'd like to discuss.
