EXPOSURE VALUE - The Exposure Value (EV) system, which originated in Germany in the 1950s, was created to be a simple-to-use substitute for the shutter speed/aperture combination, using a single number instead of two.
Exposure values (EV). EV settings are a way of adding or decreasing exposure without the need to reference f-stops or shutter speeds.
Exposure value (EV).
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.

What Is Exposure Value
You've seen it on some web sites where instead of giving the shutter speed and aperture used to take a picture, the exposure value (EV) is given instead.
Exposure Value. A number representing equivalent shutter speeds and lens apertures combinations for the same exposure, given a scene brightness. At ISO 100, 0 represents (f/1.0 at 1 sec); 1 = (f/1.4 at 1 sec) or (f/1.0 at 1/2 sec); 2 = (f/2.
Exposure value a combination of shutter speed/aperture.

Exposure value set by user, with value set by selected metering method as 0.

* In our previous tests of dynamic range this has been the average for most digital SLR sensors, we are developing a standardized dynamic range test which will be used for all our D-SLR reviews in the future.

Exposure Value (EV). The amount of light required for a given exposure. At a given ISO, certain shutter/aperture combinations will produce that exposure, e.g.
Exposure value (EV) - scale of values used to indicate the sensitivity range of a TTL or off-camera meter system within which accurate exposure measurement is guaranteed.
Exposure value. Method of quantifying scene brightness. Most of these values apply to metering cells, how high or low e.g.
EV, or "Exposure Value" is a measure commonly used by light meters. While keeping ISO constant, equivalent combinations of shutter speed and aperture are all assigned the same EV number. An exposure of 1 second at f/1.
EV. Exposure Value. The ability to override the auto exposure system to under or over expose the image.
EV - Exposure Value, a very complex thing but in the digicam world it usually means the ability to override the auto exposure system to lighten or darken an image.

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.
Larry, 1.0 EV (Exposure Value) is a synonym for 1 stop (a.k.a. 1 aperture stop). 0.3 = 1/3 stop; 0.7=2/3 stop (the numbers are rounded off).
Thanks, this helps a lot! ...
Exposure Value; A number that represents available combinations of shutter speed and aperture offering the same exposure effect when scene brightness remains the same. Each EV number can be applied to various shutter speed and aperture combinations.
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.
If your camera does not have a bracketing setting, you can manually adjust the aperture or go into the menu settings and manually adjust the exposure value (EV) settings between shots.
When you combine a shutter speed and an aperture you get an 'exposure value'. The table shows a range of shutter and aperture combinations which will all result in the same exposure value.
The process of defining the light levels in a scene and providing a measurement for a proper exposure value.
Two scales are most useful for images-exposure value and contrast ratio. Exposure value (EV) is easier to use, while contrast ratios better display logarithmic increases in light intensities.
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.
-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.
A visual representation of the exposure values of a digital image. Histograms are most commonly illustrated in graph form by displaying the light values of the image's shadows, mid-tones, ...
Any lens attached to the E-P1 will deliver blur-free images thanks to three modes of In-body Image Stabilization that compensate for up to four steps EV (exposure value).
EV - Stands for 'Exposure Value', which is the amount of shutter speed or aperture adjustment required to double or halve the amount of light entering the camera. It is also referred to as a 'stop'.
Using this mode, a series of shots - each adjusted to a different exposure value - is taken in succession. This is very useful in tricky lighting conditions where it is difficult to assess the settings.
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.
The one thing that sold me on the D700 was the fact that its full-frame sensor made it 2EV(Exposure Values) faster than my D300 and that's something very important when you shoot with natural light in very low-light situation as I do a great deal of ...
qtpfsgui should automatically determine exposure values from the EXIF data, but in some unusual circumstances you might have to do it manually.
You may want to bracket a still life, say, altering the aperture, and keeping the same exposure value by also altering the shutter speed. You will get a series of exposures of the same density, but going from shallow to long depth of field.

Exposure Compensation: Changing the exposure set by the camera by increasing or decreasing it. Usually set as + or - EV [exposure value].
File: A single document stored in memory or on disk or hard drive.
With today's digital devices, such as the Adorama Ambient 1° Digital Spot Meter and the Sekonic L-558R DualMaster, the exposure reading is displayed on the meter's LCD in the form of shutter speed and aperture, EV (exposure value) or luminance.
- Continuous servo autofocus
- Lock the center focus sensor
- Center-weighted metering
- Aperture priority (usually wide open)
- Possibly some negative exposure value (EV) to avoid blowing out white jerseys. Hopefully not more than -1.0.
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.
Set the camera to program, turn off the flash, crank up the ISO a bit and let your compact digicam do the rest. If they are too dark, push the exposure value setting up to +2/3 or so. Too hot? Dial back to -2/3 or so.
Overexposed image (too light) - Should have locked in focus and exposure on a lighter area, then recompose. Also could have used Auto Exposure Bracketing or changed the EV (exposure value) to a minus (-).
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).
Then I work out the exposure difference in stops between the two values and choose the appropriate filter for the difference before setting the exposure value for the foreground reading on the camera.
