I've written about using noise for aesthetic purposes. I've also explored the possibility that noise generated by boosting a camera's sensitivity (ISO) will become a historical artifact and thing of the past. I've also explained my strategies for effective noise post processing. It's time to take a look at a technical challenge that decreased noise generation at higher ISOs solves....

I've been shooting in low light at ISO 6400, partly on the grounds that my Nikon D300 is remarkably low noise, and partly on the grounds that noise can be used as part of the aeshetic of an image. My photos of the jellyfish in the aquarium tanks at Monterey are examples of this kind of high ISO work. However,...

In my spring release from O'Reilly Light & Exposure for Digital Photographers, I show that image noise can be used creatively. This material is in the ISO and Noise chapter. For example, the noise in this close-up capture of a tiny Lobelia flower is what makes the photo interesting. View large size. Photoshop Nyet: see my blog entry for backstory...
