New MLV2DNG tool (need help)
« on: April 05, 2014, 05:32:41 PM »
Hi everyone,

I'm coding a tool to convert MLV to DNG files.
This tool could read directly mlv file and set in and out points before to export to dng.

I understood many things by reading sources code of magic lantern but when I extract one image raw from frames data I get a image very green and dark (see my screen shot - I used debayer algo. ).
I can understand the result, i would like to know the best way to obtain the best colors for the viewing (temperature, expo and color)



PS : This tool'll be an open source and it'll run on all OS.


tks for your anwsers

Eddy

please read the definition of the color-matrices and their functions. they're described in the adobe dng-papers.
