A bright image will have mainly pixels with high intensities and therefore the peak or peaks of the histogram will be to the right.
Quarters & Thirds
A dark image will have a histogram that is mainly to the left. Below is the histogram for the above image. Clearly, it is a moderately-bright image.

For each pixel in a gray-scale image, the intensity is stored as an integer number. Bit depth refers to how many integer levels are used to encode the intensity. If your camera was only able to capture a one-bit image commonly known as a binary image , the only possible values would be 0 or 1, and the only tones that would be represented would be black or white:. If the image had a bit depth of two, there would be four values 0, 1, 2, and 3 and the image would be in the four shades of black, dark gray, light gray, and white:.

Notice that we have gained some detail, but the image is still poor in quality. In the histogram for this image, below, we see huge gaps between the tones. This is referred to as "choppiness" or "posterization". Another way of thinking about choppiness is that it indicates there is missing information in the gray levels that were not encoded.
Let's examine the same image with a bit depth of 5, which is 2 5 or 32 possible values. In the 5-bit image, we have gained a large amount of detail, but there is still some obvious posterization in the sky - note the abrupt, unrealistic transitions in grey levels. The histogram also shows the choppiness:.
This image shows the full detail of the scene with no visible posterization, and the histogram looks much better.

So why not stop here, with 8 bits and values? In fluorescent imaging of biological samples, the problem of stopping at 8 bits is two-fold.
The first problem is that if you want to contrast-enhance your image in Photoshop and when you do enhance an image, it is always good to acknowledge that you did , you are expanding the tonal range of the image in some range of levels. This can create choppiness and the loss of fine detail. Note how the enhancement process pulled apart the histogram.
The more you push the enhancement, the more you widen the gaps in the histogram. On the other hand, bit files have 4, tones, and bit files have over 65, Is Christian a terminator?
Emilia Clarke turned down Fifty Shades of Grey due to nudity
He is many things—a pianist, a pilot, a pervert, and a tremendous bore—but evil is not in his wardrobe. Lavishly stuffed with the tools of domestic torture, it is supposed to radiate a breathless lust, although the result looks more like a spread from House Beautiful. Your body tells me something different. So how does the movie, directed by Sam Taylor-Johnson, stack up against the book?
My inner goddess is thrilled. On the other hand, the film, by dint of its simple competence—being largely well acted, not too long, and sombrely photographed, by Seamus McGarvey—has to be better than the novel. It could hardly be worse. Yet we should not begrudge E. James her triumph, for she has, in her lumbering fashion, tapped into a truth that often eludes more elegant writers—that eternal disappointment, deep in the human heart, at the failure of our loved ones to acquire their own helipad.

And how much of this kit gets used? He looks like Roger Federer, practicing gentle cross-court lobs at the net. And there you have the problem with this film. It is gray with good taste—shade upon shade of muted naughtiness, daubed within the limits of the R rating.
