In the last few months, I’ve been examining ways to get the highest signal-to-noise ratio (SNR) in digitally-captured images.  I started with ETTR, then explored the issue of optimal in-camera ISO setting. Now I’d like to explore how to get your camera punching above its weight – producing images with the SNR of a larger… [Read More]

rfoto folio has just published an interview with me, mostly about the Staccato series that forms the basis for my half of the upcoming In Motion exhibition. That show opens at the CPA gallery in Carmel, CA on March 9, and runs through April 27. You can see the interview here. You can see the… [Read More]

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]
