About
This is a modification of Dave Coffin's dcraw, which prints histogram of raw data. The output is 5 columns. The first one is value and next four columns are number of Red Green Blue and second Green pixels with that value in a RAW file.
Please, don't use it for any sort of important tasks, because I've made it just for fun and to learn, how camera works. It works with Canon's and Nikon's files, others may not work correctly.
Compile it with
make
Run without any options:
./dcraw-hist
Sample output:
VALUE R G B G
1 0 0 0 0
2 0 0 0 0
3 0 0 0 0
4 0 0 0 0
