Comments on: Common DSLR Myths - Always Use The Lowest ISO http://cameradojo.com/2007/12/01/common-dslr-myths-always-use-the-lowest-iso/ (brought to you by a couple of middle-aged, overweight guys with no martial arts training) Formerly L7Foto.com Thu, 28 Aug 2008 19:02:59 +0000 http://wordpress.org/?v=2.6.1 By: KerryG http://cameradojo.com/2007/12/01/common-dslr-myths-always-use-the-lowest-iso/#comment-275 KerryG Tue, 25 Dec 2007 16:53:34 +0000 http://l7foto.com/2007/12/01/common-dslr-myths-always-use-the-lowest-iso/#comment-275 Thanks for your comment Chuck and I may revisit this one if we get enough comments like yours. While in a perfect lab environment the results may prove to be different but in real-world tests where you have things like wind, motion, breathing, etc to deal with, shooting at a low ISO means a slower shutter speed and thus more bluring.

Hardly. I have to say that this is a perfectly inadequate test by someone who seems not to understand what they are doing from a technical perspective. First, critically examine the text of the article. These test shots are made hand held and at relatively large magnification. The ISO 100 shot is at 1/250 second which is well within the range for problems from camera motion, especially for a small sensor camera at close-up range. Second, carefully observe the position of the leaf in the ISO 800 shot compared to the other three shots. The leaf in the ISO 800 shot has been pushed up and to the right by an invisible force... called the wind. So we have the camera in motion and the subject waving in the wind and we're supposed to judge sharpness. In fact, although noisier, the sharpest photo is actually the ISO 1600 shot. Pay attention not to the leaf but to the bottom of the pot and what looks like a clump of peat moss. At ISO 1600 the 1/4000 sec shutter speed has finally stopped all motion. In fact, I'm not completely convinced that we're not also seeing some changes in depth of field, possibly from changes in aperture. The ISO 1600 shot at 1/4000 sec should have been taken at 1/3200 sec if the light had not changed. Why was it taken at 1/4000? What aperture was used and why? Perhaps what the tester says is true. I don't know. But you sure can't make any judgments from this test. Chuck Norcutt Busted? Hardly.

He brought up the point that many beginner and/or inexperienced DSLR owners (myself included until just recently) will shoot at a low ISO at the expense of having to deal with motion blur in their photos due to the long exposure times made necessary by the low ISO. In nearly all cases, it's much more acceptable to have a bit of noise in the image than to have motion blur. Noise, to some extent, can be reduced fairly effectively in post-processing, while unintended motion blur renders photos useless.
