CornerFix 1.0.0.0

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.

Here are some key features of "CornerFix":

- Does not require that lenses be coded
- Does not require the the Leica IR filter be used ? any filter, e.g., Heliopan, can be used
- Allows corrections to be adjusted separately for luminance and chroma
- Corrects DNG files directly ? any DNG RAW developer can be used, e.g., C1, Lightroom, etc
- Free ? distributed under the GPL. Note that some portions are copyright Adobe.
- Profiles for any aperture and/or and lighting can be produced
- 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.
