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.
ISO is how sensitive your camera is to light, shutter speed is how long it takes for your camera to take a picture (which in turn alters the amount of light coming in), and aperture is how dilated the lens of your camera is. Not all cameras have this, mostly only digital photography cameras.
