XnView Software

sorry. been out of town for a while. just got back and have
been trying out some things.

i've been running nconvert from a script (wxp home/powershell).
the script is simple, just running through all my canon 5d.cr2
raw files in a given folder and cropping and resizing them, then
outputting them as .tga files.

i posted a bug report in the bugs forum but thought this might
be some kind of settings issue. the problem i'm concerned about
here is that i find that nconvert seems to be auto-correcting the
exposure of each image even though i've given it no instruction
to do so.

i've checked the images with canon's raw viewer and they seem
fine. a good example is a series that were taken from afternoon
through sunset to dark. the raw shows the gradual darkening
sky. the nconverted images, however, remain bright throughout,
the last (taken well after sundown) just as bright as the first.
the last is also considerably noisier due to this correcting of the
exposure.

am i missing a setting here?

fwiw, here's my command line from the script:

nconvert -out tga -crop 286 374 3856 2169 -resize 1920 1080 -o output.tga input.cr2

does changing a setting in the xnview gui app have an effect on
runnning nconvert from the command line or a script?

thanks,
BabaG

more info. i have the same images captured in both raw
and jpg format. when i run the same script on the jpg
images, the auto-correcting seems not to happen; the
skies darken naturally as the series progresses.

i made no changes to any settings. all i did was change
the "cr2" references in the script to "jpg".
