Brightness Range Method This method requires you to take two readings from the scene: one from the highlight area where detail is desired and another from the shadow area where detail is desired.
Brightness and Contrast
Very often, when we upload our pictures to the computer from the camera and first look at them on the screen, they will appear dull and lifeless like photo No.1 on the right.
Brightness range
Techniques Glossary Brightness range
The difference in luminance from the darkest to lightest areas of the image.
Brightness/Contrast on an adjustment layer is perfect for darkening things because it does exactly what the darkroom burning used to do-it darkens everything equally.
The same brightness increase with Legacy turned off leaves a bright image, but one that still has some black. The histogram has shifted right, but is still anchored on the left end too.

This series shows three exposures of the same subject and the histograms for each exposure. As you can see there is a significant difference in the distribution of light and dark pixels.

This is the point where Bright Layer lives up to its name. With Bright Layer still selected, use the brightness slider to greatly overexpose the image.

Brighthness is a discreet measurement that indicates the distinction in luminance from the darkest area of a picture to the lightest area of the picture.
Brightness
The value of a pixel in an image, representing its lightness value from black to white. Usually defined as brightness levels ranging in value from 0 (black) to 255 (white).

Brightness: Some camera phones will change the birghtness level regardless of the actual light that is letted in to the camera. Do mess around this feature, some camera phones brightness controls will emphisize the highlight levels.
Brightness - Describes how light or dark we perceive a color to be. The higher the brightness value, the closer the color will be to white. The brightness of a color is the same as its value.
Brightness
Brightness is the perceived intensity of light coming from the image itself, rather than any property of the portrayed scene. Brightness is sometimes defined as perceived luminance. (From Adelson, MIT) ...

The Brightness control is designed to affect the midtones. In addition to the default setting, conversions were done at 0 and 100.
Brightness and Contrast
Editing software can correct a number of problems with brightness, sharpness and contrast in dull or fuzzy pictures. In fact, an otherwise perfect photo can be easily ruined by a slight problem with lighting.

Brightness
One of the advantages of moving from CRT to LCD monitors is the increased brightness of the monitors makes it easier to read text on screen with less eyestrain and movies, video games and photos take on an extra brilliance.
Brightness. Value of a pixel in a digital image giving its value of lightness from black to white, with o being black and 255 being white.
brightness adjustment
In digital terms, increasing the brightness of an image means increasing the colour components of each pixel without changing the relative amounts so that no hues are altered.

Brightness range. The range of brightnesses between shadow and highlight areas of an image.
Brightness: In color, the difference in range from white when compared to dark tones and colors. Could also be considered to be contrast. In photography, brightness is dependent upon correct exposure.

brightness
(1) degree of reflectivity of a sheet of paper or similar substrate for blue light measured under standardized conditions by reflectometer calibrated for the wavelength of 457nm. (2) the overall intensity of the image.
Brightness
The balance of light and dark shades in a image. Brightness is distinct from contrast, which measures the range between the darkness and lightest shades in a image.
-Brightness range - subjective term describing the difference in illumination between the darkest and lightest areas of the subject.
-Brilliance - intensity of light reflected from a surface. It is sometimes an alternative term for luminosity.
LCD brightness helps you avoid eyestrain when looking at images in different light. Pump it up to full brightness if you're in direct sunlight, but if you're viewing in a darkened room you may want to dim the finder.
Brightness & Contrast Control: This allows you to lighten or darken the image as well as increasing or decreasing contrast.
Curves: Curves is used to adjust brightness and contrast of each tone separately.
Brightness, as the name implies, is the amount of light in the picture. The longer the lens was open and the wider the lens aperture, the brighter the resulting picture will be. Every photo editing program will have a Brightness control.
Brightness usually needs to be toned-down a bit in digital images, but contrast is tricky. The human brain loves to see highly contrasted images, but designers and photo buyers do not.
Brightness and contrast. In most software, these controls are typically applied uniformly throughout an image, thus changing the exposure's appearance. Some software will give you the option for selectively applying each control.
Brightness or intensity of either a light source or a reflective surface.

Pretty much what it sounds like - this increases or decreases the luminance of a photo or selected area by whatever amount you specify. 0 means no change.

The Brightness slider is equivalent to the midpoint slider in levels and sets midtone brightness. If you push it up too far you can start to affect the exposure setting and you’ll start blowing out highlights.

A pixel's brightness level.
Gray Scale
This is the spectrum of shades of gray and black and white of an image.
Any given brightness level, requires a certain sensitivity to capture it. In my diagram, I encoded the brightness levels of a scene with colors. A dark scene requires a sensitive camera system (slow shutter speed, wide-open aperture, and/or high ISO).
So, if the brightness of the pendulum is greater in the left eye than in the right, ...
Change the brightness
So what do you do if your picture looks too bright, or if the histogram is stacking up steeply towards one side?
The reflective brightness of fog and mist fool most autoexposure systems into allowing for more light than is actually available, so you'll have to increase exposure over your camera's recommendation.
An image where brightness appears consistent and uninterrupted; each pixel in a continuous-tone image uses at least one byte for its red, green, and blue values. This allows 256 density levels per color or more than 16 million color mixtures.
Shade
The brightness or luminance of an image when compared to a gray scale.
Shadow Point
The darkest tone printable in an image without being black. All tonal values below this threshold will print as black.

The ratio of the brightness of light falling on the subject from the main (key) light and other (fill) lights. A ratio of about 3:1 is normal for colour photography, greater ratios may be used for effect in black-and-white work.
