Playing with RAW

I was using the Proxel X3F tool to look at the actual raw data in a Sigma X3F file and decided to play with the extracted image.

I extracted a TIF with a gamma of 1.0, then applied a tonal curve. The results almost remind me of a faux infrared rendition.

diglloyd:x3f lloyd$ ./x3f_extract -gamma 1.0 test.X3F
Load RAW from test.X3F
Dump RAW as TIFF to test.X3F.tif
min = 13
max = 3581
gamma = 1.000000e+00          
Sigma DP3 Merrill , raw extraction at gamma 1.0

The color version is far more appealing in general, but it’s always useful to keep in mind other possibilities for unusual purposes.
