Comparison of the Sony FS100 at all gain settings. I pointed the FS100 at a DSC Labs Billups VF/X chart, at a small enough size that I could extract a pixel-for-pixel extraction of the gray and color patches. This combined video shows all the various gain settings, at a 1:1 pixel level. Then, for further clarification, I blew up the settings so that the video is approximately 250% blown up on the horizontal and 200% on the vertical, to exaggerate the presence of noise, to make comparisons easier.
Using the chart lets you see what noise appears in every tonal range, from the darks to the highlights, and also whether noise appears in certain color ranges.
