A CCD can theoretically be run in reverse to generate surface charge, but practical applications may be limited. Photocopiers and laser printers utilize static charge to create patterns, which could inspire alternative methods for achieving similar results. Creating a photographic negative or positive and projecting it onto a photosensitive material is suggested as a viable approach. It's important to select the right type of CCD, ideally one that allows reverse clocking and has appropriate test inputs. Overall, while the concept is intriguing, its utility for specific applications may require further exploration.
