This set of three images, A Study in HDR 1-3, shows the results of high dynamic range imaging followed by tone-mapping for an interior scene lit by halogen lights as well as ambient light. The first image is the mid shot of 11 exposures, each approximately 1 stop apart. This shot is then the camera's automatic best exposure for the scene. The full EV range turned out to be 13.4 stops, slightly more than the Canon 5D Mk 2 working range of 11-12 EV. Auto White Balance was used throughout and the camera set upon a tripod. Manual mode was used to allow the large number of exposures to be made. The software used was Canon's Digital Photo Professional v3.9.3; Photomatix Pro (64-bit) v4.1; and Picturenaut v3.2 from HDRLabs. Apart from the HDR software the only significant post-processing was sharpening (via DPP) of the tone-mapped images followed by scaling down for posting.
The second image in the series is that from using Photomatix Pro, with its default settings. The third image is that from Picturenaut, using the Adaptive Logarithmic method and adjusted to my best eye.
This first image shows a warmer tone than my eye would see, but covers a good dynamic range, particularly the view out of the window, the computer screens, and the prints on the walls. The main failings are in the shadow areas with no tonal differentiation of the "black" carvings on the window ledge, nor any of the seat in the foreground and the dark areas associated with the computer and printer etc. An exposure of perhaps 2 stops more might bring such details out, but at the expense of blowing lighter areas (the lamp bulbs are already blown).
