Exposure Values (EV)
Exposure value refers to the amount of light for a given exposure. It is denoted as a single number.

Exposure values (EV). EV settings are a way of adding or decreasing exposure without the need to reference f-stops or shutter speeds.
Exposure - exposure values are in increments equivalent to f-stops. An adjustment of +1.00 is similar to increasing the aperture 1 stop. Similarly, an adjustment of -1.00 is similar to reducing the aperture 1 stop.
By comparing the exposure values below we can state that the Canon EOS 300D is approximately 0.
When the Sabatier exposure is strong, the optical density in the film or paper approaches a high value on going to very low initial exposure values.
In the next dialog photomatix will ask you for the exposure values (still remember the settings from your RAW converter?).
Press OK and Photomatix will generate an HDR image for you.

Important note: Optimal exposure values are unique to this particular strobe-to-subject distance and power setting. Consider them as comparative indices between the films, as well as a rough indicator of true speed as opposed to rated ISO values.
You can also change the suggested exposure values for creative effect. This moody nebulous image was actually a bright cloudy sky.
Usually describes a graphical relationship between exposure values and image density of a printing paper. Each brand of paper may have a different initial characteristic curve.
-Paper characteristic curve - describes a graphical relationship between exposure values and image density of a printing paper. Each brand of paper may have a different initial characteristic curve.
The range, usually indicated as a range of EVs (exposure values), that the meter can work in. The larger the range the more versatile the meter. An ISO film speed is usually quoted to indicate what the measurement scale is based on.

By making two conversions, each with different exposure values, you can get results as good as if you had bracketed when you shot.
The film speed rating is automatically detected by the camera, which is used as a basis for setting the exposure values for the shot. Focus and aperture settings are done automatically by the camera for optimum exposure.
For photographers interested in incorporating more dimensions in the exposure values, the Additive system Photographic Exposure (APEX) is a more comprehensive measurement that also takes the shutter markings into account.
A function enabling the possible change of equivalent correct exposure values under Programmed Auto Exposure Mode, to either increase/decrease shutter speed or aperture.

Beginners and amatures alike need to understand the general rules of composition, as well as light, exposure values, DOF, hyperfocal distances, and so forth.
Film holders are available as accessories for some medium format cameras. The most usual case is the Polaroid back taking instant film, often used to check exposure values, color rendition, etc. before taking final photographs on conventional film.
Bracketing is the practice of shooting one picture at the given light meter settings, and then quickly shooting two more shots, with higher and lower exposure values.
Your camera, unless it is extremely basic, offers exposure compensation. What this means is that you are overriding the exposure values (aperture and/or shutter speed) determined by the camera's light metering system.
But basically, ISO film speeds are established by exposing the film in question to a range of exposure values, then giving it a specified degree of development in a specified developer.
Each increase in the ISO level in the camera brings a compatible increase in the sensitivity of the camera’s sensor or film to light, and effects the exposure values (for example, 400 ISO is twice as sensitive than 200 ISO).
If you're familiar with the Maryland state flag, you'll also note more accurate color in the 80a image. The main drawback to using the 80a filter is the loss of two stops worth of light as evidenced by the exposure values.
