For my astro image calibration program I wish to use the RawProcessor.imgdata.color.black value but I have noticed for the Canon T5i and T7i this parameter is zero. For my Nikon D5300 the value is 600 which I believe is correct. I believe that for these Canon cameras the black level should be in the 2,000 to 3,000 range. Is there a better way to determine the correct black level?

I'm having this strange error, where i wanted to upgrade the library, but my program keeps using the old version 0.19.5-Release.

Things i've done to upgrade:

first - thank you for all the new code

my working (tested on other libraw) will not compile the new code

for now just eg the samples

I use make -f makefile.mingw

my ignorance

error
no matching function for call to "std::basic_filebuf:: open(const wchar_t*,std::_IosOpenmode) etc etc

looks like my compile string is incomplete

help please

When I am processing raw files using LibRaw I check that the camera is supported by looking it up in the array of supported cameras pointed to by LibRaw::cameraList(). For most cameras so far this has worked well so long as I use a case independent comparison (e.g. Fujifilm versus FujiFilm). I do this so that I can warn users that their camera isn't supported by LibRaw because the results may not be as expected.

Hello, I've recently come across some strange behavior related to the Panasonic Lumix DC-G9's hi-res mode raw files and apps that I believe use libraw for decoding (such as the photos app in windows with the raw codec).

The first issue I've experienced is an unnatural green tint with both the hi-res raw file and the 20mp raw file that gets taken simultaneously in the hi-res mode. A shot with the same settings but not utilizing the hi-res feature does not show this issue.
