Red 500, 1000, 2000, and 4000 ISO comparison images
Published by Matthew Jeppsen July 16th, 2007 in Cameras, NewsHot on the heels of the 8000 ISO test image, Red Digital Cinema has posted 4 more comparison frames between 500 and 4000 ISO. Mike Curtis has a mirror. At first glance, the 500 and 1000 ISO frames look essentially noiseless. You can see the grain start creeping into the blacks at 2000 ISO, and 4000 looks a bit rougher and slightly desaturated. It’s funny, when comparing frames from this camera against each other, you start getting picky. I have to remind myself that I’m examining a relatively clean image shot at ridiculous ISO levels…I’d love to see comparison images from competing cameras at equivalent ASA. Anyone?

The 8000 ISO was simply amazing. What is the lowest ISO on the camera? Where would I find that?
I believe the native signal to noise ratio of the Mysterium sensor is reputed to be around 250 ASA. See this thread for more details. These being prototype cameras, that number obviously may change. For more info on ISO, ASA, and SNR in digital sensors, here’s a quick primer. FreshDV editor Kendal Miller also wrote a good article on signal-to-noise ratio not long ago.
