For the past 40 years I've been making photographs in both black & white and color, with various camera formats, and in a range of print sizes. I own the rights to all of my work, unless a right has been expressly sold or conveyed by me.
Because I've had my prints made by several labs, I cannot control proof prints, press prints, and exhibition prints that have been taken from the lab or other venues without my permission or knowledge. Some of these unsigned prints have found their way on to eBay. The sale of these violates my intellectual property rights.
