Various digital cameras suffer to some extent from sensor blooming. This problem results in pixels near a seriously overexposed pixel also becoming saturated. Sensors vary dramatically in how much leakage there is between pixels. The processing of the raw sensor data can contribute to the severity of this problem. For example, when a color channel is saturated, it is common that the interpolation process will spread saturation to white rather than corrupt the color. Less-than-subtle sharpening can cause dark outlines around the saturated areas. The worst-case result is something like the infamous white orbs too commonly found in images taken with the Fujifilm X10.
This WWW tool, available from http://aggregate.org/DIT/DEORBIT/, is a test interface to the 20120328 version of our deorbit tool, built specifically to reduce the artificial appearance of the white orbs. It does this by recognizing orbs in saturated regions, synthesizing credible detail for these regions, and then brightening toward the centers. The tool will be released as public domain full C source code, but is made available here now to collect more test cases for improving it. Any images submitted here will be logged and may be used as test cases for improving the program further before release of the stand-alone version. To prevent use of this site for file-sharing, images submitted will be be made inaccessible shortly after they are submitted... so do any parameter tweaking (using the sliders below) soon after submitting an image.
