NConvert parameters not consistent with XnView

Post by Inept »

I've got some disappointment about Nconvert and XnView relation. I run XnView to determine appropriate parameters for image processing using its Autoview feature, and then run Nconvert with those parameters. But I've got a much different result.
For instance, I've used -gamma 0.5 -contrast 50 -brightness 20.

Is it possible to make XnView and Nconvert producing identical result when the same set of parameters is in use?

Thanks.

You must use -brightness 20 -contrast 50 -gamma 0.5
