Noiseography is a brand new photographic technique. It works by separating out the digital noise in an image and then working to create an image using just the noise. The steps used in creating a Noiseograph are shown below.

Noiseography is certainly an interesting technique. It makes use of something everyone else tries to get rid of. While everyone is complaining about the noise in digital images, here's a way to make use of it. Sort of like cutting up a pig and then finding a use for the oink.

But there may, in fact, be some practical uses for Noiseography. One such use would be a formal method for studying and quantifying the noise in digital photographs.

I'm working on a concept I call "urusai." It's the noise equivalent of bokeh. The main concept is that the quality of the urusai in a digital image is more important than how much noise there is.

Some digital noise is streaky, some noise resembles large blotches of color. All are objectionable. But my DMC-FZ5 and my Sony DSC-F707 produced noise that looked like film grain. Not so objectionable. I would give both a high urusai rating. My Minolta A2, on the other hand, as well as my FZ28, both have very bad urusai.

I'm still working on names for the different types of noise. Gotta have names, you know.
