Tips of Digital Camera Sensitivity

In the traditional film cameras in the name of the sensitivity of ISO standards in the ISO definition of a digital camera and film of the same speed on behalf of the CCD or CMOS sensor light-sensitive ISO higher values show the ability of light-sensitive photographic material, is the stronger. ISO is as S = 0.8 / H (S sensitivity, H for the exposure.) We see from the formula can be, the higher the sensitivity, the requirement calculated after exposure. The light-sensitive film ISO 100 is twice as fast 200 ISO, in other words, ceteris paribus, is NIKON EN-EL11 battery ISO 200 film the exposure time needed for half of the ISO 100 film. In the digital camera, she can change, how much light and brightness values sensitivity according to by adjusting the size. Therefore, the sensitivity to an indirect control of image brightness has values.

In the traditional 135 film camera, film camera sensitive measurements of sensitivity is equivalent, ISO said generally expressed digitally, digital, the greater is the greater CANON NB-4 battery direction of rotation, where the procedure commonly used ISO 100, 400, 1000 and in General, the higher the sensitivity, the more coarse particles of the film, reinforces the effect of the poor, and a digital camera, that is also the ISO value used the light metering system of the lower base ISO, which called for exposure is higher.

Sensitivity of the camera itself is at all not traditionally sensors for the quantitative degree brand, because the sensitivity is only sensitive material in a particular exposure, development, test conditions, radiation. Who uses traditional camera, the VGP-BPS13A / b battery film knows the most important indicator is the measure of the sensitivity - the popular thing is how much light the film, complete and accurate exposure needs values. We bought the camera to save 100.200.400 film, digital, that the speed is. ISO sensitivity value indicates general use, this value increases, the film sensitivity, more light, so that you can shoot in a different light. ISO100 film as the best suitable in the sunny outdoor shoot, but the film ISO400 can indoors or at dawn, dusk and other shots in low light conditions.

Because however different cameras and ordinary camera to an Olympus LI-40B battery CCD uses light-sensitive devices or CMOS, the number of exposure is a request, also a question of whether it light sensitivity. This has also a certain sensitivity is the same movie, digital camera manufacturers, to the understanding of digital camera users, the General will of the CCD camera which is sensitivity (or sensitivity to light) converted to the equivalent of the sensitivity of traditional facilitate film that argument will have a digital camera "instead of sensibility".

Measure of film speed with the usual high and low view of the current distribution in the digital camera sensitivity, high-speed range, the lowest for the ISO50, the highest for the ISO6400, the majority of ISO100 or so. Some digital cameras is the sensitivity of a single, with the light-sensitive NIKON EN EL1 battery CCD tolerance combined is very small and limited so that in the light of strong or too weak under the terms of the results. Other digital cameras have a few sensitivity range fairly, but also in the allowed range, the sensitivity is too high or too low, there are differences between shooting in the rule best hit stable should be placed on the sensitivity. And traditional cameras, low ISO number for the creation of a clear, soft images is a high ISO value is not sufficient to compensate for the lighting environment.

In low light, Flash is inevitable. However, is in some situations, such as exhibitions or performance do not allow the use of Flash or uncomfortable circumstances the ISO value can increase the brightness of the images. Digital camera ISO value adjustable, so that we can sometimes only increase the ISO value, exposure compensation increases and other measures to reduce the use of Flash number. Increase the Sony BP-511 battery ISO value can increase the brightness, but can also noise in images.
