success! cr2 issues fixed

Post by BabaG »

just done preliminary tests so far but with v4.79 i've
found the 'high_res' and 'raw_camerabalance' options
have made cr2 files function properly.

thanks so much pierre!

(can't wait to try this all out on a linux system!)

I didn't see a -hi_res option, but -raw_camerabalance greatly improves my CR2 to JPEG conversion in August 2020

mydir> nconvert -raw_camerabalance -keepfiledate -out jpeg IMG_6723.CR2

My first attempt, without -raw_camerabalance was really washed out. I found this suggestion in the forum and find that it helps a lot!

Do you have an up-to-date copy of the NConvert help file? I don't use RAW and in fact I don't have a camera, but at a quick look I see these options for 7.39:

Code: Select all

-half_res              : Load half resolution (Camera RAW)
-embedded_jpeg         : Load embedded jpeg (Camera RAW)
-raw_autobalance       : Auto balance (Camera RAW)
-raw_camerabalance     : Camera balance (Camera RAW)
-raw_autobright        : Auto brightness (Camera RAW)
-raw_gamma value       : Gamma (Camera RAW), default=0.6
-raw_brightness value  : Brighness (Camera RAW), default=0.8
-raw_redscale value    : Red scaling (Camera RAW)
 -raw_bluescale value  : Blue scaling (Camera RAW)
There may possibly be more.
