Hi.
I try to use ImageCalibration for crop image:
Target Frames: Canon_40D.cr2
Disable Bias/Dark/Flat. Enable Overscan and set Image region to 0,0,100,100. #1234 unchecked.
After execution output file(attached) 16bit integer 100x100 pixels, but all pixels = 0.0
![Huh? ???](http://pixinsight.com/forum/Smileys/default/huh.gif)
Best regards,
Nikolay.
