I've tried to correct automatically a series of bracketed images taken with a Canon 7D. Now it does seem to introduce a kind of supersaturation and overall inconsistency.
The way I've used this was:
for f in *.CR2; do
ufraw-batch -exposure=auto $f
Is there a better command to ensure coherency from one picture to the next?
for the record, I'm using Ubuntu 12.04 LTS with ufraw 0.18
Others probably have a better way to do this, but I would suggest loading a
"typical" image and adjusting it, then setting the save options to save the
extra data only as the starting point for when ufraw comes up. Then process
all the rest without the -exposure=auto.
