Obtaining correct exposure is a setting combination of aperture and shutter speed. For example, your camera's light meter may have measured a need for an aperture of F8 at a shutter speed of 1/30 sec.
Correct Exposure
Generally speaking a correct exposure is one in which the highlights (the lightest parts of the photo such as the sun reflected on the water, the whites of the eyes) are bright without losing fine detail, ...

A correct exposure is a simple combination of three important factors: aperture, shutter speed, and ISO.
The correct exposure value can also be read off a neutral test card or 18 percent gray card (or even the palm of the human hand) held in front of the subject.
Getting correct exposure with most simple auto-exposure cameras is easy: press the shutter button and the camera does the rest. More technologically evolved (i.e., expensive) cameras often provide a choice of several exposure and metering modes.
CAMERA'S CORRECT EXPOSURE
For this early morning contrasty image the sun was behind and to my left. The tall spike is the sky area and the graph area to the right of the spike represents the boats.
Calculating correct exposure can sometimes be difficult. Nobody can determine correct exposure all the time. This is especially true if you are working with a scene that includes very bright or very dark tones, or when working under uneven light.
Correct exposure is photography basics and what all good pictures are about. Exposure is the term for how much light the sensor receives.
give you the correct exposure.
be sufficiently fast enough to freeze movement within the scene.
be fast enough to prevent camera shake.
Quite often the correct exposure for a background in a scene is not the best one for the foreground or viceversa.
How do you get a correct exposure of your skiing subject - or any other subject in bright snow under a bright sky - when the built-in meter in your camera is likely to underexpose because it reads the bright white of the snow and the bright glare of ...
As said before, the correct exposure is achieved by choosing the right combination of shutter speed and aperture.
From experience, you estimate the correct exposure time to be about 15 seconds. Because your estimate may be incorrect, a logical procedure is to expose a test strip in four sections. To make the actual test strip, you must do the following: 1.
The ultimate tool for determining proper exposure Correct exposure is critical, maybe even more so for digital capture than film, especially color negative film.
Early cameras only had a manual mode (M) where the user had to select the aperture and shutter speed manually to ensure the correct exposure.
Correct exposure of the subject is key, so placing this in the correct zone is all we have to consider. Once this is done, any background either falls within or outside the recordable gamut. But it does not affect the picture.
It has a sensor, which measures the amount of light needed for a correct exposure, and then adjusts flash duration accordingly.
If you don't have a hot shoe, a slave flash would be an alternative.
Term used to describe how a flashgun works in conjunction with a camera's metering system to deliver correct exposures automatically.

When set to the Program mode, the camera sets the shutter speed and Æ'-stop for a correct exposure of the scene. However, at a moment's notice, you can change that combination (to a slower/faster shutter speed or to a wider/smaller Æ'-stop).
Most cameras automatically determine the correct exposure for the lighting conditions. Sometimes, however, the scene will appear too dark or too washed-out.
A system that automatically sets correct exposure by linking a camera’s exposure meter with the shutter or aperture or both.
Faster films are able to attain correct exposure in less time than slower films.
To ensure correct exposure, most analogue and digital cameras feature automatic light metering. Internal or external cells measure light intensity and convert the information into an electrical signal.
(This is an easy-to-remember trick for photographing any sunlit subject that photographers relied upon prior to the days of autoexposure.) Simply put, the correct exposure for an object lit by bright sun can be a shutter speed of 1/the ISO of the ...
Programmed Auto: Camera sets both shutter speed and aperture for correct exposure.
Shutter-Priority Auto: User selects shutter speed and camera sets matching lens aperture for correct exposure.
Therefore, before setting the correct exposure, it's important that you ask yourself which setting is more important to keep for your specific shot. Is the aperture more important or the shutter speed?
They need to be slid up and down in the filter holder with the transition from clear to dark falling accurately on the horizon or the light sky where you want to obtain a correct exposure.
The camera's light sensor measures flash illumination, as reflected by the subject on the film and shuts off the flash where measurement indicates a correct exposure.
The sunny 16 rule (a.k.a "Sunny f/16 rule") acts as a rough guide for estimating the correct exposure settings on a sunny day.
If you find that you are missing shots due to exposure problems, either work on your procedures for determining correct exposure, or bracket more to make up the slack.
Bracket in smaller increments the more sure you are of your exposure.
" The Sunny-16 rule states that when the light is good and falls on the subject (usually between 10 a.m. to 3 p.m. on a bright, sunny day with the sun at your back), the correct exposure setting is f/16 and a shutter speed that is the reciprocal of ...
Take your pictures and check for correct exposure (things not being lost in shadow, no blown highlights) on your LCD.
This means, if you are shooting at a subject 1 meter away at full strobe power, at ISO 100, F10 will give you the correct exposure. At 2 meters away, you will need a larger aperture, F5.6. At a half meter, you would use F20.
Center-Weighted: A method of determining the correct exposure for a photograph which gives more importance to the light meter reading at the center of the frame than to the peripheral areas.
Camera makers extol metering systems that deliver perfect exposure every time, but here's the reality: Often there is no one correct exposure. That's why Las Vegas shooter David Thompson makes a habit of bracketing all the important pictures he takes.
In other words, it is very important that you get the correct exposure when using slide film.
Print (C41) This is the film we are all familiar with.
Using shallow depth of field to isolate your subject from the background can therefore be very difficult in bright situations, as the camera will immediately close down the aperture to obtain the correct exposure.
Taking a light reading from an 18% gray card guarantees you a correct exposure, provided that your main subject is lit at the same level. Get your subject to hold the card and zoom in so that the card fills the frame.
I'll assume that you have a good basic understanding of how your camera works, how to get correct exposure, the compositional rule of thirds, and the good basic compositional elements of line, shape, and texture.
The text above may help you to get a technically correct exposure.

Getting the correct exposure is most of the effort of learning photography, and hence the main thrust of this article. Playing with creative effects like long exposure is much easier once you have exposure down to second nature.
A (Non-TTL Auto mode on Nikon Speedlights) The flash uses its sensor to measure the flash illumination reflected back from the subject controlling flash output to give correct exposure.
Each photograph taken as a bracket of the assumed correct exposure will be either overexposed or underexposed. In some situations these over- or underexposed photographs may be preferable to achieve the best quality.
A method of determining the correct exposure for a given photograph which gives more importance to the meter reading at the centre of the frame than to its periphery.
When a modern camera with a multi-segment exposure meter (Matrix) is used with a dedicated flashgun the correct exposure can be obtained for both the subject and background using 'Automatic Balanced Fill Flash'.
A function enabling the possible change of equivalent correct exposure values under Programmed Auto Exposure Mode, to either increase/decrease shutter speed or aperture.

The reduced size of the aperture means that the amount of light is less, and therefore to maintain the same correct exposure the shutter has to be open longer.
