My friends have requested to purchase a platinum print of one of my photos. The problem is, it's on a 4x5 negative, and I'd like to make an 8x10 print. I have a nice scan of the image, but the problem is, I don't have a really nice printer. Since I won't be doing this sort of thing often, I'd really just like to get a lab to print the enlarged negative for me, but I am having a heck of a time finding a lab that will print onto Pictorico or something similar. The only possibility I found was photofusion.org in the UK, but they have not responded to my inquiry.
So basically, does anyone know a lab that will print a negative for me? Preferably one in the USA? Or, any other suggestions?
