![]() ![]() This is much more difficult to do well using photographic methods than it is now by using the methods of modern digital image manipulation. It is also possible to make composite photographs by overlaying the print with a hand-cut mask, performing an exposure, and then using the inverse of that mask to perform another exposure with a different negative.Similar methods are available with contact printing, but it is more difficult to see the image as it is being manipulated. Using these techniques it is possible to make significant changes to the mood or emphasis of a photographic print. The tool is kept moving to avoid producing a sharp edge at the region boundary. ![]() A mask with a hole can be used to add extra light to an area 'burning', which will have the effect of darkening the regions with additional exposure, while the use of a small wand to reduce the total exposure to a region is called 'dodging' and has the effect of lightening the regions with reduced exposure. Changing the amount of light exposing the paper in various areas will change the image density in those areas.
