I added ideal photon noise to the test of the previous post, assuming that the camera’s ISO dial is set to 100. Here’s the simulated uncompressed raw file demosaiced by bilinear interpolation: And here’s the file companded by the Sony compression algorithm and demosaiced in same way, subtracted in a linear color space with Adobe… [Read More]

A tough test of Sony raw compression
[Added March 17, 2014] A reader posted a comment that you can see stating that there must be a systematic flaw in my simulation. He was right. Details are in the comments attached to this post. I fixed the error, and the results are reported at the bottom of this page. [Now, on with the… [Read More]
