Whether this is where you found it or not, the definition you give for "Unity Gain ISO" comes from the Clarkvision web site's section on digital sensor performance. As an updated version of that page explains, it's a silly concept. To quote: The fundamental reason Unity Gain is not relevant is because the sensor in a digital camera is an analog system, ...

Unity gain is such ISO number at which camera outputs pixel values roughly equal to numbers of electrons in cells. Native ISO is such ISO value at which the maximum number of electrons in cell is matched to saturation point. It is almost always division instead of multiplication for sensors with big enough electron capacity per cell. Native ISO is as unique ...

In photography tone is the range of lightest to darkest part of an image. Human eye can distinguish brightness range from details in the lightest areas to darkest with ratio 1:1,000,000. Film or digital image sensor have tonality range of 1:200. It’s 5,000 times less sensitive than our eye.

I found some information on DP Review like "The latest crop of sensors used by Nikon (D3x, D3100 and D7000) are rated with base ISO at 100 value. The previous generation all had 200 base ISO (D300, D3, etc)." From the sentence, we can see that "Base ISO" is the lowest ISO Value a camera can offer.

I would say the most important part in still life is how you can perceive and capture the light and the textures of various shapes. That would be kind of a rule to make it interesting.

To quote from Wikipedia: A still life (plural still lifes) is a work of art depicting mostly inanimate subject matter, typically commonplace objects which may be either natural (food, flowers, dead animals, plants, rocks, or shells) or man-made (drinking glasses, books, vases, jewelry, coins, pipes, and so on). So, you can think of it as "thing ...

Usually table top photography, usually intended as artistic. Still life is things that don't move, like fruit bowls or pottery, could be food, etc. http://www.google.com/search?q=still+life+photography

The focal length engraved on the lens is the distance from lens to image; this is usually stated in millimeters. The focal length is the fundamental measure of the power of the lens. A “normal” lens delivers a view that is about the equivalent of the perspective we see with our unaided eyes. A camera delivers a “normal” view when the focal length of the ...

A non technical explanation to a non photographer... Use simpe terms. On this page I am explaining something like that to construct panorama images: http://www.otake.com.mx/Apuntes/Imagen/EnviromentMaps/ On the especific subject (about half the page) I use a very simple measurement method. A person. Start building form there. At one person's distance you ...
