| stoft | "Hmmm, well the RAW data should have the same scale units which would be unsigned 8-bit integer from 000 to 255 -- so the Y axis should show noise h..." | Read more » | about 8 years ago | |||
| stoft | "Well, except there's still a problem with the plot. The smallest increment looks to be '4 steps' per scale units of '10'. Either there was some mul..." | Read more » | about 8 years ago | |||

| stoft | "Yes, it's called quantization; the camera only has 8-bits and the scale of the two plots is likely about 3-5x different. Take a look at the 'red' p..." | Read more » | about 8 years ago | |||
