Here are the images from the preceding post. As usual in this read noise analysis series, they have been scaled into the range [0,1], have had a gamma curve of 2.2 applied , been res’d down to 640×480, and JPEG’d. ISO 160, no filtering: Note the commendable lack of hot pixels. I wonder if that’s… [Read More]
