Q. In your reviews of the Canon 5D Mark III and Nikon D800, I was surprised at the lengths your reviewer goes to discuss the noise in these models at ISO 12,800 and up. I guess I’m old-school—started with film and Acufine in the 1970s, when pushing film 4 stops was considered radical, albeit often necessary. So, given a “normal” ISO of 100, I typically push my speed with my digital cameras to around 800 (3 stops) or 1,600 (4 stops), but never anywhere in the range of 25,000. I just don’t foresee myself shooting at these high ISOs simply because the lighting isn’t what I need. Am I looking at this the wrong way?
A. We agree that photographers should boost ISO no more than necessary to get the image they want; we discuss noise issues so that people can make informed decisions on the best settings to use. But note that DSLR makers have made astounding advances in noise suppression at stratospheric ISOs. So much so that we’d say that images captured with a Mark III at ISO 102,400, converted to B&W, would have finer grain than Tri-X push-processed 4 stops to ISO 3200.
