Applying a verification classification system to medical and forensic digital images.

This paper gives the definitions, and describes the application, of a classification system for photographic veracity relating to medical and forensic images. It uses practical examples to demonstrate the reasons and parameters for using such a system. It also calls for continued discussion on what the limits and extent should be for the parameters. A debate encompassing the advantages and disadvantages of manipulating photographs goes back well before the introduction of digital imaging and has continued since the introduction of photography in the mid-nineteenth century. This author's first foray dates back twenty years (1). The introduction of digital imaging only gave the debate new impetus and new problems to solve (2), some of which might be resolved as suggested in this paper.

Placement considerations when using linear scales in photographs.

This paper considers several aspects of using linear scales in photographs. It describes a method used to measure the variations in scale size and subject size when the two are not on the same plane in a photograph. It discusses the results achieved from experiments using a measuring device and different lenses and lens settings. The results demonstrate the marked differences in measured size that occur as the scale and subject distances vary. The paper provides evidence that placement of scales within the field of view in photographs is critical for useful information to be extrapolated from the scale.
