Canon 80D is not supported yet by Dcraw/RT. I am readying a camconst.json with support for new models but it is a mesh at the moment.
But as a preliminary step you can insert in the existing camconst.json (after 70D) the following lines …
{ // Quality C, White Levels not properly indicated, aperture scaling..missing scaling factors are guessed
"make_model": "Canon EOS 80D",
"dcraw_matrix": [ 7457,-671,-937,-4849,12495,2643,-1213,2354,5492 ], // DNG_V9.5 D65
"raw_crop": [ 264, 34, 6024, 4022 ], // full size 6288x4056, official crop 276,46,6275,4045

"ranges": {

],

}
},
If any 80D user reads this … we need some sets of samples to improve the above
- a set of VERY overexposed shots of a featureless surface, covering all the frame, completelly out of focus (+5EV or more, so that all pixels are burned) at all ISOs (100-125-160- …51200) at f/4.0 or f/5.6. Keep the exposure shorter than 1 sec and set LENR to OFF
- a set as above but with long exposures (i.e at the 30sec limit) and with LENR (Long Exposure Noise Reduction) set to ON.
If 1) +2) is too much just upload 2)
- a set as 1) but only for ISO100, 125, 160, 200 and using all wide appertures available (f3.2, 2.8, 2.5, 2.2, 2.0, 1.8, 1.6, 1.4, 1.2…)
If ISOs 100-200 is too much, just upload ISO160.
give me your email pls.
