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 number is known as the film's âISOâ. The higher the ISO-number, the more sensitive the film is to light. In digital photography, the ISO plays a similar role. That is: The ISO-number is a measure of how sensitive the camera's digital image sensor is to light. The same principles apply as in film photography: The higher the number, the more sensitive the sensor is to light. The ISO of a particular film and the ISO of a particular digital sensor are set by the manufacturers of the film or the digital sensor.
