Summary

The following guide outlines critical parameters to determine if a new camera can be used effectively with existing exposure techniques. We must establish whether dynamic range limits need expansion or if the sensor's noise performance is sufficient. If intermediate ISO settings are required for low-light performance, we must verify that they do not significantly degrade contrast or color fidelity by introducing noise. Furthermore, we must confirm whether the camera shifts from pure analog processing to combined analogdigital systems, as this alters the overall dynamic range and potential for distortion. We also need to examine non-linearities such as flare, glare, and incorrect black levels to ensure RAW data remains accurate. Accuracy, repeatability, and uniformity are essential metrics; we must test multiple shutter speed and aperture ranges to guarantee consistent results across different scenes. It is vital to evaluate white and black frame variations to assess pixel variation and detect any optical or sensor lens skewing. We must also verify histogram accuracy and correct vignetting from the lens, digital sensor, or optical mounts to ensure that the camera's inherent limits are respected. Finally, dark current and non-uniformities, specifically PRNU and DPNU, must be investigated to ensure low-light performance remains stable under varied illumination conditions.
