Latitude and noise comparisons between digital cameras and a radiographic film scanner.
The test image generated by a radiographic laser printer was used as a test object to measure the latitude and image noise of two digital cameras and a dedicated radiographic film scanner. The film scanner had the widest latitude and least image noise. A Kodak digital camera had a wider latitude but more image noise than an Olympus camera. A blue filter on the Olympus camera increased the latitude without significant increase in image noise.
