I just hung a 16x20 of that first photo in my office at work. I'm trying to decide if I should matte it or not. Cost-co does a weird thing with their posterboard large prints. I order a 16x20 and you get that size in board but with a half inch of white all the way around it....meaning the photo is like 15x19 and change. In the large frames I am using, it sort of adds its own border. I wish I was more artistic. Taking them to have them professionally matted costs BIG BUCKS, especially in that size. I think it would be cool to throw in a duck stamp or something like DU does with their prints, into the matte. Funny thing is I suck at color choice and everything that has to do with matting, and I am usually somewhat artistic.
For those that ordered prints, I got them.
