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.
Scanners are subject to the same saturation:noise criterion as for dynamic range in digital cameras, except it is instead described in terms of density (D). This is useful because it is conceptually similar to how pigments create tones in printed media, as shown below.ynamic range in photography describes the ratio between the maximum and minimum measurable light intensities (white and black, respectively). In the real world, one never encounters true white or black â only varying degrees of light source intensity and subject reflectivity.
