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.
Metering sensitivity range is specified at 1-20 EV (at 23Â°C/73Â°F, with EF 50mm f/1.4 USM lens, ISO 100). The Canon 7D's Exposure Compensation setting allows the user to increase or decrease the metered exposure by up to five stops positively or negatively, in one-third or one-half EV increments.
