Luminance - Wikipedia, the free encyclopedia
Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through or is emitted from a particul...

Luminance (relative) - Wikipedia, the free encyclopedia
Relative luminance follows the photometric definition of luminance, but with the values normalized to 1 or 100 for a reference white. Like the photometric definition, it is related to the luminous fl...

Photometric brightness is an old and deprecated term for luminance. ... Luminance (usually 'L' in formulas) is the amount of visible light leaving a point on a surface in a given direction. This "surface" can be a physical surface or an imaginary plane, and the light leaving the surface can be due to reflection,

This section is designed to help you develop a better understanding of how luminance and color both vary within an image, and how this translates into the relevant histogram. Although RGB histograms are the most commonly used histogram, other types are more useful for specific purposes.

4. LUMINANCE is the luminous intensity per unit area projected in a given direction. The SI unit is the candela per square meter, which is still sometimes called a nit. The footlambert (fL) is also in common use (1 fL = 3.426 cd/m^2). The concept of luminance is challenging and deserves detailed discussion.

We went to Phoenix and Tucson over Thanksgiving weekend and visited with family and friends, it was a great trip. I also broke out the Nikon and the iPhone a bit, of course. The animal photos were all taken at the Arizona-Sonora Desert Museum ... For those of you interested in the gear, ... Posted by Will at 4:57 PM 0 comments ...

This tutorial shows a powerful luminance-equalization technique, which can enhance both the underexposed and overexposed areas of an image, without reducing the overall contrast of the shot, and without any manual selection of regions.

4. In the Layers window, slide the Opacity down to 50%. If you were only trying to correct luminance shifts, then you could also change the Blending Mode for this layer to Luminance - but in this case, we need to fix both the color and the brightness, so it stays at Normal.
