Hello to all! I have a question about Noise Reduction software for Photoshop. I understand the principle of using it for High ISO images to reduce noise. What I am wondering is can it be useful in Lower ISO (100-400) range to reduce noise in long expsosures. In addition to nature photography which can require long exposures, I am photographing the interiors of some home porches using available light. I seem to be seeing some noise in the darker shadow areas. I am photographing with a Canon 1Ds Mark II, and for the interiors, using the 24mm tilt shift lens.
Thanks,
J. Paul

Best bet is to do a free download of Noise Ninja demo. Even on 1600 ISO, I wasn't impressed enough over what i could do in PS to make me want to buy it.

I use neat image and think it just fine. Havn't used Noise Ninja.
As to the quesstion regards reducing noise in long exposures. When you say noise what exactly are you referring to. if you mean the gritty grainy appearance of images shot at high iso then the noise reduction software will help. If you mean the "mad pixels" that you get with long exposures then noise reduction software will not help in my experience. With mad pixels I am referring to the random scattering of hot points you get usualy in dark areas and usualy red on my MK11. These need to be removed manualy.
I feel it is not useful to agonise too much over the issue of noise. An image with strong content can stand a little noise. I have also found that it is best to evaluate noise at 50% not 100% on a monitor as that is closer to how it appears in print.
Noise reduction and sharpening need to be part of an intergrated strategy. They work together either for or against each other. It is for example pointless to agonise over noise reduction and then use very harsh and unsophisticated sharpening methods that exagerate noise.
