This image is a photo illustration. Move your mouse onto and off of it to see a direct "before-and-after" comparison with the original photograph. Shown above is actually a simplified version of the process involved in creating the "after" image -- I used not only the three smaller photos as sources of image material, but two others, as well, because of the extreme range of color and contrast (I made a total of five exposures of this image). For example, the colors in the distant part of the hallway were most influenced by the artificial lights, which were slightly yellow. In the vicinity of the doorway, however, the colors were varyingly influenced by blue skylight coming in through the glass (it was a clear day). Outside, it was necessary to balance brightness and color between directly-lit areas and shadows. My goal was to reproduce with reasonable accuracy what the eye actually perceives. This serves to illustrate what a powerful instrument the human eye/brain system is.
