The tail is black tipped. The white winter coat is the source of the common name ermine, which is a French word for white winter color. The ermine has a typical weasel shape; a very long body, short legs and a pointed face with an almost triangular head. Its tail is about 30 to 40% of its head and body length.
Before we go any further, you should first understand how DSLR cameras work. In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called âimage sensorâ or simply âsensorâ.
This makes the pixels a bit like a well. When you make pixels very very small, the proportion of photosensitive area goes down and the depth of the well as a proportion of it's width gets much larger, reducing the number of angles it can receive light from and thus the sensitivity.he main idea here is that bigger sensor yields better picture (if the sensors use the same technology). What Apple have done is to increase the sensor size, and by keep the same number of pixels each pixel will have a higher signal-to-noise-ratio, resulting in a better picture.
