My friend needed help in reading histograms on his samsung digital cameras. I had to look-up further understanding for myself. I was not sure that I was reading the histogram right.
There is always so much to learn. The more settings there are the more figuring there is!

Optical Picture Stabilization, which physically adjusts the CCReading your histogramHistograms What it is: A way of judging the exposure of an image on camera, without relying on minuscule and often inaccurate LCD screens. Where to find it: Typically, histograms can be found by changing the display mode during image playback on your digital camera, or by enabling live histograms in your digital camera settings. What it does: An image that looks perfect on the digital camera doesn’t always turn out that way. It’s frustrating to take a photograph you love when you see it on your digital camera’s LCD screen, only to get home and find the highlights are blown or the detail is lost in the shadows. Histograms are one way to get a better idea of what you are actually seeing. A histogram is a way of visually displaying the image data within a photograph. It is a graph of the pixels within your image based on brightness. Darker pictures are crowded on the left-hand side, with brighter pictures on the right. A good exposure has no brightness data that touches either of the outside boundaries of the graph on the right or left side - that indicates clipping. By looking at your histogram, you can judge whether there will be any clipped highlights or shadows. If there is, adjust your shutter speed or aperture accordingly and retake the shot. Images that are overexposed will have a histogram that has brightness data clipped on the right-hand side. Many digital cameras today are beginning to have live histograms that will indicate the exposure setting before you take the shot. This can be immensely helpful, so check to see if it is an option on your digital camera. What to watch out for: Chewing up your battery life looking at the histogram display. Otherwise, there really is no downside to using histograms.
