![]() The opposite is true for the the black slider. When you see this, Photoshop is showing you which parts of the image will be overexposed, or clipped. As you slide to the left, you will see some red areas in your image (see above). When you click ALT and hold down the white slider, the image will go black. ![]() If you want to see how your adjustments are affecting your image, hold down the ALT key (PC) or OPTION key (Mac) while you click on the white or black slider. Small changes always work best, so don’t make extreme changes on each slider. ![]() Then you can move the middle slider to the right or the left to see which works better. There are some great articles about histograms on the dPS site, so if you want to learn more about them, click on one of the links above. There is no right or wrong histogram, it is simply a representation of the light in your scene. If the graph is pushed over to the left side it means that your image has more darker tones in it, if the graph is over on the right side it means that your image has more brighter tones. This graph is called a histogram.Ī histogram is simply a graphical representation of the pixels in the scene. You will see the LEVELS dialogue box pop up and it will have a graph in it. Go to: IMAGE > ADJUSTMENTS > LEVELS on the menu bar (or using the keyboard shortcut Command/Control+L). If your image is a little over or under exposed, the levels tool can fix that. With your image open and the shadows adjusted, you will now adjust the overall exposure in the scene. If you see them appearing, simply drag the sliders back to the left until they disappear. This glow is often referred to as a halo which can be avoided by watching carefully how your adjustments are affecting your image. Once you start seeing a “glow” around certain parts of your image, you may have gone too far. The amount that you decide to adjust the shadows is up to you. If you need to extract more detail from the shadows then slide the Amount slider to the right even more but make sure you line the other two sliders underneath it. You will be able to see at a glance how your changes are working. Click on the preview button on the right hand side of the tool (you can do this with all the tools in this article) to see the “before and after”. The important thing to remember here is to make the adjustments and take careful note of your image has been affected. In most cases, you will want to have these sliders directly under each other (see screenshot below right). Lastly bring the radius slider to directly under it. Then slide the Tonal Width slider to directly under the Amount slider. The best way to work with the tool is to slide the Amount slider under the Shadows box to about one third across (33%). Making adjustments to the Shadows in the image Open your image in Photoshop and go to: IMAGE > ADJUSTMENTS > SHADOW AND HIGHLIGHTS. The Shadow and Highlights tool will bring back some of the details in those areas. Modern cameras can capture lots of detail, but depending on the light in the scene you are shooting, the shadows may be a little dark. This tool will be used to get more detail in the shadow areas of your image. I will go into more details about adjustment layers in upcoming articles, for now, if you follow these guidelines, your images will look compelling and rich without looking overdone. The only tool that can’t be used with an adjustment layer is Shadow and Highlights. You could also use an adjustment layer which gives you much more control over the adjustment. NOTE: the examples in this article simply show you how to make the adjustments on a separate layer. Depending on what you want to achieve with your photos, this quick guide to five Photoshop tools will help you adjust your exposure effectively and make the colour really pop out of your image.
