film speed

the relative sensitivity of film emulsion to light or radiation exposure; speed is inversely related to detail resolution.

film speed

The sensitivity of a photographic medium (e.g., a radiograph) to light or radiation. The film speed is determined by: the size of its silver halide crystals; the thickness of the emulsion; and the presence of radiosensitive dyes. Films are described as “fast” if the film requires little radiation to produce an image and “slow” if more radiation is needed.

Estimation of the ISO speed with which portrait was shot (Table 5) shows that the photographers-experts portraits taken with ISO 400/27 and ISO 3200/36 generally evaluated as photographs taken with lower sensitivity, which is especially expressed in portraits taken with the ISO speed of ISO 3200/36 (not a single photographer-expert did not estimate that portraits were shot with the sensitivity of ISO 1600/33 or more).
Observers also had to determine which ISO speed was used while shooting (by the experience of the gained effect in the classical photography systems).
As an example, the Hormann Iso Speed Cold door panels have a thermal U-value of only 0.
1-megapixel High-Sensitivity CMOS image sensor work together to enhance low-light image quality at a maximum ISO speed of 12800.
Once the firmware is installed the EOS 7D will also be able to process RAW images directly in the camera, allowing dynamic adjustment of exposure compensation, white balance, picture style, noise reduction at high ISO speeds, distortion correction, and other processing parameters.

Leveraging the company's latest pixel innovation, called Aptina[TM] DR-Pix[TM] technology, the 16MP MT9H004 imaging solution was recognized for its unique ability to deliver maximum signal-to-noise ratio (SNR) across all scene lighting and ISO speed conditions.
The result is a sensor, like the company's MT9M024, that offers the best possible noise performance over all ISO speed conditions.
