![]() ![]() recommended exposure settings of the camera proved not to be suitable, and a published image would have been selected from one of the other nearby exposures. Histograms are shown to illustrate the general distribution of values, and are not necessarily to the same scale for each image. ![]() Tone mapping and exposure fusion images were generated in Photomatix Pro 3.0 so ftware using ‘default’ settings. HDR radiance map was constructed using estimated relative EV values of +5, +4, 0 and -2 respectively for images 1 through 4. Scanning was done with a Nikon 4000ED film scanner. Image B was generated directly from the four scans without the need to construct an HDR radiance map using exposure fusion. Image A (bottom left) was generated from that using the detail enhancement method. Specific exposures were not recorded for these slides, so some experimentation with different estimates of their relative exposures was used to generate a suitable HDR radiance map. These are from excavations at the Cove, Avebury in 2003 but are fairly typical of ‘legacy’ photographic material that exists in many archaeological archives. The four images (numbered 1 to 4) were scanned from a sequence of bracketed Fujichrome colour slides. ![]()
