Nonlinear exposure times with the IQ3

Postby NN635907312285264754UL » Mon Aug 21, 2017 6:55 pm

I currently am using a Phase One IQ3 (100 MP). The camera is connected to a PC (Intel Core i7 3.40 GHz; 16 MB RAM; Windows 10 64-bit) via a USB cable. We are using both the Capture One application and our own program developed using the CaptureCore SDK.

My question is a simple one. I have found that if I reduce the exposure time by half, the pixel values do not decrease by half. Thus, the default behavior of the IQ3 seems to be nonlinear. Is there any way to ensure linear behavior from the IQ3?
