I’ve tried to photograph my own work for years, and it never worked well. I couldn’t get the painting square, neither the color nor the detail could be captured properly, and they were barely usable for my portfolio and website.
I’ve also used professional scans of my paintings. While these turned out better than my personal photographs, details were often lost, the color wasn’t always accurate, and I had issues with banding when producing prints.
I’ve used several professional photographers that specialize in art documentation, including at local museums. None have come close to capturing the amount of detail and accuracy that Mitch achieves with his photographs.
