DMF Developed Software: WFM (Waveform Monitor)
WFM displays a pixel value profile (from black  to white ) for the row of image pixels under the mouse cursor (here indicated by the green line). Traversing the whole image vertically while watching the WFM graphical display reveals whether or not the image to be collected utilizes the full range of grey values offered by the collected bit-depth. Generally, the entire line profile is moved up with increasing brightness, while the amplitude of the profile is increased by increasing contrast (although these two are also linked). "Flat troughs" (loss of detail in the dark areas of the image) and "truncated peaks" (loss of detail in the light areas of the image) should be avoided.
