How to use the Histogram and RGB Highlights on your camera

An easy and reliable way to check your exposure

Using the LCD screen on the back of your camera is the worst thing you can do if you want to check your exposure after taking your photo.

Why…?

Well, you can adjust the brightness of the LCD screen, artificially making you think the exposure is okay, when it isn’t.

The best way for you to check your exposure is to use the Histogram or the RGB Highlights function of your camera. If you have no idea what I am talking about, now would be a good time to grab your camera and find out how to access the Histogram and RGB Highlights.

What is a Histogram?

A histogram is a graphical representation of all the pixels in your photo. As colourful as your photo is, it is actually made up of Black, White and every shade of grey in between. The histogram graphs out all of the pixels to show you how many of each shade of grey you have, and we want to avoid pure black and pure white (we only get black or white when we under or over expose)

When you review your histogram, you want the graph to look like a mountain, or a series of mountains. It doesn’t really matter what it looks like, as long as it is not bunched up against the right or left wall of the graph.

The best way to learn how to use the histogram is to grab your camera, shoot an image overexposed and one underexposed, then take a look at the histogram for each image. You will quickly learn what you’re looking for.

RGB Highlights

My second favourite and the quickest way to check your exposure is to look at the flashing RGB Highlights. You will have to turn this on in your camera.

This is not as thorough as it only tells you what areas of your image are over exposed, although, to me, this is more important than being underexposed,

Sometimes called ‘The Blikies’, parts of your image will flash if it is over exposed or Pure White.

If you get flashing highlights you need to retake the photo and aim for a lesser exposure.

Anyway, watch the video and I will show you step by step, hopefully you found this helpful.
