Resizing Digital Images to Actual Size (1:1) Using Adobe® Photoshop®

Guy Pierce


Photographing fingerprints, footwear prints and impressions, and tool marks is standard practice during a crime scene investigation. However, if those photographs are going to be of use for comparison at a later date it may be necessary to print the images to a 1:1 scale. Of course, there are cameras and lenses available that will capture 1:1 images automatically, but most of us use a standard 35mm or digital SLR camera. Using Adobe® Photoshop®, it is relatively easy to print 1:1 images, regardless of the type of camera you use or the relative size of the original image.
