At first, you might think this means the image is underexposed, but remember: this is only the histogram of the green channel.

Here is a good example of such a photograph: X-E2 + XF23mmF1.4 R 23mm, ISO 320, 1/250, f/1.4 Note that this particular image was exposed differently upon capture - I altered its brightness using software, but it is fully representative Exposure Lesson #5: How to Read a Camera Histogra An underexposed image is the sort of photograph that one might consider to be too dark. Your camera may also have a highlight alert option for when you are reviewing your photosĪn underexposed scene will have both a sharp peak (due to the black or low-value pixels) as well a concentration of pixels on the left side of the histogram (due to the low exposure If you create a photo that's technically underexposed, the histogram might appear this way: If you were to look at the above image's histogram on its own, you might think the image it represents is. There will be no detail visible in the extremely dark and/or light parts of the image. You have underexposed and/or overexposed pixels. Unless it's what you want, adjust your shutter speed, aperture or ISO! 5 If your histogram graphic is showing a spike at the left or right edge this represents high contrast. Similar to an underexposed histogram, just vice versa - with such histogram, you'll lose details in bright areas as they are completely white and can't be recovered. And a spike on the far right side that touches the edge will indicate that your image has blown-out highlights The spike on the vertical axis indicates there's too much darkness.

The pixel brightness data at the far left represents true black tones captured by the sensor If your histogram shows a spike on the left side that's touching the edge of the graph, your image is severely underexposed. This is a classic case of a strongly underexposed histogram. Underexposed Histogram Looking at the first image in the comparison table, we can see how the histogram data is stacked to the left of the graph. This can be corrected by adjusting the exposure. The graph on the histogram shifts toward the left. This is an example of an underexposed image. When you see a histogram like this you know that you should increase exposure The graph on the histogram shifts toward the right.

The large gap on the right side of the graph indicates that the photo is underexposed. Histogram example 4: An underexposed photo I underexposed this photo by around two stops to show you what happens to the histogram.
