Conversion from RAW to TIFF, PNG, or JPEG is darker

[jimoe]

nikon d700
nconvert 6.17

Using the command line

Code: Select all

nconvert  -high_res -raw_autobalance -raw_camerabalance -raw_autobright -out jpeg -o ../%.jpg *.nef

produces output that is noticeably darker than the original NEF image. Looking at the histograms confirms this since the overall curves are the same, only compressed toward the dark side.

Other than the "-raw_" options, is there an automated way to get the correct brightness?

Hello,
... You can try with an icc profile, for you ... NikonD700.icc ...

I tried using "-icc_in" with the d700 profile available from the site you referenced. All it seemed to do was excessively increase the color saturation without any brightness benefit.

The "-icc" option made no difference.
