Right. Let's see some "mode 3" shots tomorrow. It switches off long exposure noise reduction / median filter.

Sure.

And leave WB preconditioning / R/B calibration scaling as it is.

I use EL lenses to evaluate in-camera raw processing, and rarely for imaging purposes - unless I need to shoot in UV or IR.

Hi. I am very excited by this post- I use D800 for scientific research. Was the link taken down for this program? I can't seem to find it.

Thank you very much for this tool.

Has anyone tested this with using remote control software to control camera over USB? I have been trying with the following procedure but It seems to put the camera in an error state and then it needs to be power cycled to communicate again-

1. run dark current enable tool, leave program open
2. run camera control software
3. camera control software gives error saying the device is busy

Thanks,
Andrew
