Essential Nikon camera settings: 4. Histogram display

Judging the exposure from the icon alone is hard, so you Nikon has a display mode to help you capture it correctly

What is it in a nutshell?

The histogram is a graph that presents you the distribution of notes within an icon. The figure of this graph will vary from shot to shot, but it's the distribution of the graph, and its location on the rear axis, that are the key factors when it comes to judging the exposure of your strokes.

Why is it so important?

Understanding the histogram will enable you to tweak your exposure to make sure that you get the upper limit sum of detail in the tones of your pictures. The horizontal axis shows you the brightness of the tones in the image, from the darkest black on the extreme left to the brightest white on the right.

The areas in between these two extremes are the lines that will be correctly displayed in your picture. If the graph goes over the right-hand border, there will be areas where the highlights will have no detail, while if it operates over the left-hand end, it will be the phantoms that have no point.

How do you use it?

To display the histogram when you review images on your Nikon, press the Play button and then toggle the top or rear end of the rear control pad to scroll through the different display modes, until the histogram is displayed alongside the picture.

If the graph is bunched to the left, with a gap to the right, and so the image is under-exposed (unless the field is really dark), hence you should increase the exposure on the next stroke; if it's bunched to the right, with a gap to the left, it's over-exposed, hence you require to bring down the vulnerability.

If you're charging a very high-contrast subject you may cease up with a histogram that overlaps both ends of the graph. In these positions you can't keep detail in both the highlights and the apparitions in a single snapshot, then you'll have to determine which is more important in your icon.

It's normally best to determine the exposure so that the highlights reach the right-hand end of the graph, and then 'let the shadows go down where they may'.

What you can ignore: RGB histograms

Along with the normal histogram display, there's the option to display separate histograms for the cherry, green and blue (RGB) color channels.

This grants you even more information about the individual colors, but in most situations this isn't necessary for finding a correct exposure, and owning to check three graphs, rather than just one, can make it more difficult to spot under- or over-exposure.

Taking it further: Highlight warning

On with the histogram, there's some other display mode available on your Nikon that can help you retain detail in your guesses. The high spots (or Clipping) warning display alerts you when the very brightest areas of the scene are over-exposed.

These areas will flash black and white, indicating that you need to shorten the exposure if you want to retain detail in these highlights.
