==Flat-field correction generation software==
A software that is supplied with several (around 20 is sufficient) raw images of an out of focus 30% grey wall and is able to generate the sensitivity offset of each photosite and a resulting flat-field correction matrix (https://en.wikipedia.org/wiki/Flat-field_correction).
The samples images are preferably done with a fast 50mm lens stopped down to F4-F5.6 facing an evenly lit surface (white wall with area at decent distance from wall light). To further smooth results the lens should be set to out-of-focus. We need to test if these measurements work even better with a lee filter in front of the sensor instead of a lens.

1 Axiom Alpha Prototype

1.1 DNG Converter Software

  • Add other DNG tags such as dead pixels, register settings, black level calibration data, etc.
  • Implement the matrix as a LUT.
  • Eventually port to from python to C/C++
