My father, Peter Krohn, creates images on his scanner. This has the wonderful advantage of capturing vast amounts of information, resulting in very sharp, detailed images. However, there are drawbacks that require extra work. First, the ability of a scanner to pick up so much information means dust particles and debris need to be removed from the image. Secondly, the photographer has limited control of exposure on a scanner compared to a camera. Photoshop can be utilized to bring out light and color values that are more true to the original.
