CornerFix for Windows is a small utility program designed to fix the "Cyan corners" problem, caused by color dependent vignetting, with Leica M8 digital cameras using IR filters. It has two main functions: to correct theraw M8 DNG files for vignetting, based on a devignetting profile, and to generate a devignetting profile from a flat field reference image.

Devignetting application for Leica M8 and M9 digital cameras; fixes the "cyan corners" problem when using wide lens with IR filters and decodes data in the M8's MakerNotes

Features:
1. Does not require that lenses be coded
2. Does not require the the Leica IR filter be used ? any filter, e.g., Heliopan, can be used
3. Allows corrections to be adjusted separately for luminance and chroma
4. Corrects DNG files directly ? any DNG RAW developer can be used, e.g., C1, Lightroom, etc
5. Free ? distributed under the GPL. Note that some portions are copyright Adobe.
6. Profiles for any aperture and/or and lighting can be produced
7. Can be used to correct for "red corners" - if the M8 with a coded lens is set for the use of a filter, but no filter is used
