I was asked about matting images for the state fair today.
I spoke to Charlie Starnes-Superintendent of the Photo Exhibit and he said at least 60% of the images that are entered are without matting. He also said many times the judges have a difficult time judging a matted image as the matting is “terrible, poorly done, wrong colors”, etc. His recommendation was to not mat, unless you use very neutral colors, i.e. white or black.
