I am an amateur photographer, but do show my photos at local contests/shows/etc. A friend turned me on to RRP and I absolutely LOVE the quality of the paper, and the price can't be beat.
Before I knew better, I used more expensive papers that were suggested online, and in large camera shops ... but RRP has a better product, better pricing, and their service is top notch!
Camera Nikon D610, Printer Canon Pro-100, favorite paper - Polar Pearl Metallic
