A reflective surface behind an image to be scanned on an optical image scanner, copier, facsimile machine or similar device. This reflective surface is dynamically adaptive to the item being scanned, copied or faxed to provide improvements such as reducing image bleed-through while maintaining a desirable level of dynamic range. Preferably, the reflective surface has a reflectance that is dynamically variable and controlled to be either all white, all black, all grey or some other color. The scanning or copying reflective background may also be varied in different regions, such that different regions of the reflective background may simultaneously be white, black, grey, or some other color. The background reflective surface of the scanner, facsimile or copier may be controlled directly by an operator or end user or by software or firmware of the scanner, copier or facsimile. The dynamically variable reflective surface of the scanner, facsimile or copier may be an LCD.
