The following is at best half-baked. I need to experiment with it to see how good it is. I thought I’d share it with you anyway, since I often get good advice from you all. When figuring out an exposure strategy based on ETTR and the effect of in-camera ISO settings on signal-to-noise ratio (SNR),… [Read More]

Over the previous 16 posts, plus the work that I‘ve done on expose-to-the-right (ETTR) (you can see it here), I’ve demonstrated – to myself, at least – several things: ETTR can produce low noise results when employed at or near the base ISO of the camera. It’s possible to mess with the camera settings, particularly… [Read More]

I got RawDigger to work on the NEX-7 files by running it on a different computer, so I have the NEX-7 results now. The self heating test at ISO 6400 and 1/4 second exposures of blackness shows some slight self heating (look at the dotted green line, which is a straight line fitted to the… [Read More]

I made all the exposures for the Sony NEX-7 testing, but I have a problem; RawDigger crashes when I try to save selections from the NEX-7 raw files, even though it works fine with the Sony RX-1 raw files. So there will be a hiatus of indeterminate duration while I wait for a fix. The… [Read More]

I ran the same series of tests that I’ve run on the D4, D800E, and M9 on the Sony RX-1. I expected to find more signs of self heating of the sensor, since the RX-1 runs with live view on all the time, but I did not. Here’s a series of closely-spaced exposures of 1/4… [Read More]
