Thanks guys. Sometime you need someone to tell you to wake up and behave. I would have thought between bias and darks decent software would sort out between pixel differences, but good point that to be technically correct need to properly correct for this. I guess I was thinking more in terms of vignetting correction. It wasn't until I considered how much faster 2x2 shooting is I even started to consider it but probably silly to shoot hours of lights without decent matching cal frames.
I'm having more trouble than I thought dimming my light box even with a decent dimmer in the circuit now. May have to rewire with LEDs is the real issue.
