One of the three pillars of photography that can dramatically affect the look of your images is camera ISO (the other two being shutter speed and aperture).Like those two settings, ISO controls the brightness of your photos, and it is a crucial setting to use properly if you want to take the best possible images.

In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance.Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.

It is difficult to take good pictures without having a solid understanding of ISO, Shutter Speed and Aperture – the Three Kings of Photography, also known as the “Exposure Triangle“. While most new DSLRs have “Auto” modes that automatically pick the right shutter speed, aperture and even ISO for your exposure, using an Auto mode puts limits on what you can achieve with your camera.

Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras.. Relatively insensitive film, with a correspondingly lower speed index, requires more ...

Procedures that help to ensure the management of records according to the principles and elements outlined in this part of ISO 15489 are provided in ISO /TR 15489-2 Information and Documentation--Records Management--Part 2: Guidelines (offered below).

Equivalence relates the visual properties of photos from different formats based on the focal length and aperture of the lens. Neither the focal length nor the relative aperture of a lens change as a function of sensor (for example, a 50mm f/1.4 lens is a 50mm f/1.4 lens, regardless of the sensor behind the lens).

Introduction. ISO Sensitivity (or ISO speed) is a measure of how strongly an image sensor and/or camera responds to light. The higher the sensitivity, the less light (smaller aperture and/or shorter exposure time) required to capture a good quality image.

Aperture is one of the three factors that create an exposure. Understanding the aperture settings makes getting to grips with taking an evenly exposed photo a lot easier. Using different aperture also opens up more creative avenues through unique effects. This post will teach you what they are and ...
