You have a digital camera and one of the functions you least use is the Histogram function? Well, you are not alone. Many people aren't aware of the features of this function, thinking of it as a statistical function. Hence, majority of digital camera users do not use this function.
But the histogram function is a really really useful tool which you can use to avoid exposure issues and hence create some great photos.
This digital photography article will show you how you can utilize the histogram function to better your photography.
So what's a histogram? A histogram is actually a graph that displays the distribution of light in your picture. The left side of the graph represents the shadows, whereas the right side represents the highlights.
In simple terms, that means that if the histogram has a high peak on the left hand side, you can tell that a lot of pixels in the picture are dark, or in shadow. A peak on the right side of the graph means that a lot of pixels are bright, or in highlights. Peaks in the middle of the graph represent pixels in the mid-tones of your exposure.
So how should a histogram of a good photo look like? When a graph shows that there are no peaks on either the left side or the right, this means that that no part of the scene is overexposed or underexposed. This kind of histogram represents a good shot.
So when you can see a peak on the left side of the graph, and the right side is not in balance, then the photo is underexposed. Whereas, when the peak is on the right side of the graph rather than the left, the photo is overexposed.
So when composing your photo, always make sure that the histogram doesn't have spikes/peaks at either extreme end of the graph, where you'll lose data and have under- or overexposed parts of your picture. Learn to apply the above tips, use them and soon you'll be taking better pictures!
