I'm planning to print some backgrounds for use mostly in hummingbird photos this summer, but possibly with some other birds as well. I want to make several to have some variety. Because these are going to be blurred OOF images to begin with, and will be blurred even further when placed as a background it seems like I should be able to go with a relatively cheap print service (which will help maximize the number I can print).
I will probably use between 12x18 and 16x24 for the hummers, and may get a couple larger ones done in the 20x30 to 24x36 range. I plan to mount the prints to foam board, or possibly even just tape them to some cardboard. The most important thing will be to have a truly matte finish so I don't get reflections when hitting the background with a flash, and I don't want any horrible color casts either, although it's ok if the prints don't color match perfectly.
Any suggestions for where to have these printed? Anyone have experience with any of the places offering matte poster prints, as opposed to photo paper? Also curious about some of the foam board print options that print directly onto foamcore. I've got time, so I may just get some samples done in smaller sizes, but if anyone can help narrow the list of places I should be looking at it would be appreciated.
