![]() ![]() Here’s how I recommend reading a new histogram: Step 1: Look at the overall curve of the graph Whereas a peak at the left side of the histogram indicates a large volume of dark pixels in the image. The graph peaks represent the number of pixels of a particular tone (with each peak corresponding to a different tonal value). So a peak at the right side of the histogram (such as in the example histogram above) indicates a large volume of bright pixels in the image. The left side of the graph represents the blacks or shadows, the right side of the graph represents the highlights or bright areas, and the middle section represents the midtones of the photo. If you can read a histogram, you can quickly and accurately check the exposure of your image while out in the field or when editing at home. ![]() That’s why photographers love histograms so much, and why learning how to use a histogram is essential. If an image has blown-out (detailless) highlights, this will be visible on the histogram if an image has clipped (detailless) shadows, this will be visible on the histogram if an image is just generally too dark or too light, the histogram will make this clear. In photography, a major goal is to capture a detailed exposure of a scene (i.e., a photo with well-rendered shadows, highlights, and midtones).Īnd while you can always check image exposure by looking at your camera’s LCD screen and/or electronic viewfinder, or by viewing your image on a computer, the histogram offers a more objective method of evaluating tones. They do create impact if used where they look natural and help to create a three dimensionality within the image by emphasising the form of an object which is depicted.Every image has a unique histogram, which is displayed on your camera and by most post-processing programs. Highlights are a compositional element of a picture. So most effective use of a highlight will be where a naturally bright spot is created, but which is not super-whitened by burn out. The eye is naturally drawn to the blackest blacks and whitest whites in an image. Highlights that burn out will be more distracting in a photograph than highlights that are bright but not burnt out. Well controlled highlights are where the photographer has found a way to reduce the light level in the highlight so it is not seen or is not bright enough to cause burn-out. Then the highlight will create bright spots with no detail. This is where the light from the highlight exceeds the ability of the camera sensor to resolve the contrast. Where the source is very bright, and particularly where it exceeds 2 or three stops of light brighter than the surrounding surface the highlight will burn out. However, small point-sources of light, or hard lights (with small size and intense power) will create highlights more often than diffused soft light with a relatively large light source.īright highlights are frequently created on rounded surfaces where the reflections cause light to be directed to the eye. Highlights are created by any bright light source. Highlights are normally created by a bright or intense illumination or by various forms of diffusion or reflection. ![]() Normally it is assumed to be one of the brightest points in the image. A highlight is a bright spot in a photograph. ![]()
