Sensitivity (ISO)
By Vincent Bockaert
Conventional film comes in different sensitivities (ASAs) for different purposes. The lower the sensitivity, the finer the grain, but more light is needed.

ISO sensitivity
ISO is the international standard used to denote film speed. It has been carried over to digital imaging and all manufacturers now provide the ISO equivalent for the sensors they employ in their camera.

Sensitivity is usually specified as an ISO setting just as the speed of film is.

Sensitivity
Sensitivity is a measurement of how something (in the case of digital photography, the image sensor) responds to light. The image sensor's sensitivity is a key component is establishing an exposure.

Sensitivity to Colorblind Deficiencies. The Design of visual documents or signage without thought to the overall contrast level between figure and ground can be problematic for people with sight deficiencies.

Sensitivity (ISO)
Like conventional film have different sensitivity for light expressed as ASA, the digital camera sensors also have a sensitivity rating expressed as ISO. The higher ISO the less light the sensor needs for a correct exposure.

Sensitivity
Sensitivity settings on digital cameras are the equivalent of ISO ratings on film. Just about every digital camera will have settings with a sensitivity equivalent to from ISO 100 to ISO 800.

SENSITIVITY - The degree to which a photographic emulsion reacts to light. Fast film, for example, has greater sensitivity than slow film.

Sensitivity
Expression of the nature of a photographic emulsion's response to light. Can be concerned with degree of sensitivity as expressed by film speed or response to light of various colours (spectral sensitivity).

Sensitivity-Priority mode
The K-7 features a unique Sensitivity-Priority (Sv) mode, which is designed to automatically select the optimum combination of aperture and shutter speed for a user-selected sensitivity.

Sensitivity. A measure of the degree of response of a film or sensor to light, measured in digital cameras using ISO ratings.

Sensitivity to Light
So far we've talked about two different ways in which cameras manage the light that is used to make an exposure: aperture and shutter speed. There are two more ways in which cameras control light.

ISO Sensitivity
Auto; ISO 100, 200, 400, 800 equivalent
ISO sensitivity expresses the speed of photographic negative materials (formerly expressed as ASA).

Sensitivity to light determines film speed ratings. Faster films are able to attain correct exposure in less time than slower films.

Sensitivity towards this issue may show a few prominent ideas. Expandable layouts for mobile and wide-screen users is always a big plus.

Sensitivity settings on a camera range from 100 to about 10,000. There are a few cameras that go well above that range but without some money to burn, you probably won't be able to afford them.

sensitivity, ISO
ISO indicates the camera's sensitivity to light. The higher the sensitivity, the less light is needed to capture the scene.

The sensitivity (ISO) setting will also have a major impact on the effects of different exposure settings.
Exposure value (EV) - this is the value calculated by combining the settings for aperture, shutterspeed and sensitivity.

ISO sensitivity AUTO, 64, 100, 200, 400, 800, 1,600
Flash Auto, red-eye suppression, force flash, slow synchro, flash off, Throw distance: approximately 0.2 to 3 meters ...

The sensitivity to light of the sensor controls the ISO range that the camera can emulate. More sensitive sensors can also permit greater pixel bit widths, and so give better colour rendition.

The sensitivity sites (and the corresponding latent image specks) of a silver halide grain can be located on the surface of the grain or in the interior of the grain, or in both places.

The sensitivity of camera gear at autofocussing or determining correct exposure metering is rated in terms of EV - exposure value - for a given lens type and film speed/ISO.

Color sensitivity of the film Filters available Black-and-White Line Originals A black-and-white line original has no middle or intermediate tones between the lines and background.

Light sensitivity or ISO also plays a big role in night photography because it determines how the camera's digital sensor will capture the image.

The ISO sensitivity (ISO rating, ISO speed) characterizes the sensor or film sensitivity to light. Formerly called ASA rating, digital cameras continue to use the same system introduced a long time ago.

The sensitivity of film is measured by ISO, and the larger the number, the more senstive the film. ISO 100 needs a lot of light, like outdoors on a sunny day. ISO 1600 doesn't need much light. However, higher ISO means more grain in the film.

A little sensitivity can go a long way in photographing other cultures. It is a practice that will allow you to come away with more than great images. It will also allow you to gain an education.

ISO (Light Sensitivity)
The ISO rating is an indication of light sensitivity in digital photography.

relative sensitivity
the degree that a photographic emulsion is affected by light.
relative viscosity
the ratio of the absolute viscosity of the solution to the absolute viscosity of the pure solvent.

Contrast Sensitivity
The contrast sensitivity function for red and green is greatest for 10 point text (spatial frequency = 1 line pair/mm = 8 Hz/degree) at normal viewing distance (46 cm) and about 14 point text at arm length (65 cm).

As a side note, the sensitivity of the respective cones to red, green and blue is not equal. That is to say the quantity of light necessary in order to produce the same sensation of intensity is different for S, M and L cones.

ISO speed - A rating of a film's sensitivity to light. Though digital cameras don't use film, they have adopted the same rating system for describing the sensitivity of the camera's imaging sensor.

Linear Response A CCD camera with a "linear response" has sensitivity such that doubling the exposure time of an object of a certain brightness will result in an image twice as bright.

Each of these four types of cells has its own sensitivity to light. The sensitivities of these cells make the human eye more sensitive to certain colors than others. This alters what the human observer sees.

Because our quarry is normally encountered in the bush, or active in the open only in the morning or evening, we therefore typically contend with low light levels so film choice is crucial - we must use film with as much sensitivity as possible, ...

Kodak's High Speed Infrared Film (HIE) has the highest IR sensitivity of the three films but sacrifices Grain size as the grain is very large. Konica Infrared film has a lesser sensitivity to IR wavelengths but has much finer grain than Kodak's.

Digital cameras enable you to adjust the camera's sensitivity to the existing light.

ISO - increase the ISO setting and you increase the camera's sensitivity to light. This means the ambient light in the room will have more effect and you'll have less need for flash.

In a parallel to the film camera world, digital cameras uses ISO to refer to the sensitivity of the digital sensor (in the same way that film ISO refers to the sensitivity of the film).

High sensitivity films are called "fast" and low sensitivity films are called "slow." A film rated at ISO 200 needs half as much light to form the same image density as one rated at ISO 100.
