On the subject of learning the camera's acceptable range:
I've gone ahead and done a series of unscientific tests of multiple exposure settings in LED indoor lit rooms (dark), fluorescent lit office rooms (normal), and outdoors (bright). In regards to the noise floor of my unit, I've found that using false color makes it incredibly easy to see. If I had to make a general summarizing statement about the results, I could stand firmly behind the following statement:
My Ursa exhibits vertical fixed noise within the following parameters:
- Visible on fold-out screen and monitor connected via SDI
- Visible without pressing record
- Visible at all false colors below middle grey (green)
- Very visible in the blue section
- Visible in the purple (pink?) section until stopping down and crushing the blacks in camera.... then the noise goes away completely
- Doesn't matter what iso, aperture, frame rate, resolution, codec, or shutter speed, the noise always displays based on the false color range of purple, blue, and black
It's great that the noise isn't visible in the range where dark skin should be exposed (green), but my honest question is: should the fixed noise be visible in the range immediately below middle grey (dark gray/black)? This is the range above "Near Black Detail Loss" so I imagine that a whole lot of information should be usable in this range, but would be subject to fixed noise if my camera sensor is deemed "normal."
Help me out
