There are many different ways that you can use to modify the properties of a digital image. Microsoft Word has great options that can let you do advanced adjustments to your digital images. In this video, author Richard Harrington walks you through how to adjust the exposure of a digital image in Microsoft PowerPoint.
- One of the first properties I suggest that you modify with an image is the exposure. You'll find that PowerPoint gives you control over brightness and contrast, and it's a good idea to adjust these properties before anything else. That's because, as you modify the exposure details, you can see a shift in saturation or color. So let's go ahead and fix some images that aren't properly exposed. Let's start by adjusting the exposure for a photo. To do this, select the image on the slide.
You can double click to switch to the Format controls. On the left, you'll find the basic corrections. You can use the pop-up menu to select from simple choices. You'll see, for example, that you can start in the middle, which is normal, or start to add brightness, or contrast as you move up. If you hover over one of the adjustments, you'll see it preview and apply to your source photo.
Now, if you go too far, you'll notice that images tend to blow out a bit, so I favor going with something a bit more conservative. Click to apply the change and your image will update. If you want more precise control, click on Corrections, and, from the bottom, choose Picture Corrections Options. This will bring up advanced controls. Here, you can easily adjust other details, adding in, by typing in numerically, the values for brightness and contrast.
If you feel like you've gone too far, you can also reset the image. Let's go to another image here. And if select that, you'll see that the Format Picture controls are still available. Just go to the fourth tab for Picture and you'll find the pop-up list here for Presets as well. This allows you to choose the choice that you want and update the photo. Generally speaking, I don't go much more than 30 to 50% on the Brightness and Contrast sliders.
It'll vary by image, but if you push things too far, the image will look unnatural. Let's go to the last image here and we'll bring this up as well. Clicking on that pop-up list, you can choose from the different choices. And you'll see that the image adjusts. Now, in this case, taking the brightness up so far tended to lead to a little bit of blown out areas here in the clouds, so I'm going to back that off to 30%.
Additionally, pay attention to the contrast settings, so that the image doesn't look too contrasty. In this case, the contrast was lowered to help, but it might've gone too far. Let's take that to a value of negative 15. And that looks a bit better to me. We still have rich shadows and the highlights aren't blown out as much. Alright, that works well. Remember, you can access these controls from the right for Format Picture, or you can use the quick presets that are available from the drop-down menu for Corrections.
Generally speaking, it's a very good idea to adjust the exposure, i.e. the brightness and contrast, before you effect other properties for an image. That's because, as you brighten the exposure, the colors can change.
