The basic properties of a simple lens may be applied to an objective lens system as well. They will help us understand the behavior of the lens. But keep in mind the fact that optical design of a complex system is a bit more involved.
Refer to the figure above for a visual illustration of these concepts. Read more
One of the best tools available for any photographer to use to make sure your exposure is neither under or over exposed is the use of the camera histogram. It is especially important for jpeg shooters. The exposure latitude (how much the exposure can be off and still get a good image) of a jpeg is less than one f-stop. Digital SLR’s have an option for a histogram to be superimposed over the image or placed next to the image in the camera’s LCD. This histogram will provide exposure information. The image below

Joseph Nicephore Niepce
In 1816 French Lithographer and inventor Joseph Nicephore Niepce started new research on an idea of recording an image onto sensitised paper using a camera obscura. Niepce first experiment was to position at the back of a camera obscura sheets of silver salts coated paper, known to blacken with daylight. In May 1816 he produced the first image of nature: a view from a window at his home in Chalon Sur Saone, France. It was the first ever negative produced, although the image vanished because in broad daylight the coated paper becomes completely black. He calls these images “retinas.” Read more

Escapism and breaking the conventions is the best way to describe the photographic works of Will Santillo. He is a photographer who is known in particular circles and lesser known outside, a man with balls who defies the critics but is acclaimed by them. He is known for working outside the boundaries of the studios , taking his art to glossy locations, using available light and most importantly non models. His subjects sit for him in unconventional circumstances, full sex scenes, oral scenes, lesbian scenes, masturbation, bondage and the subjects pay him to sit and to be entered into one of his books.
