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 color of a digital image in Microsoft PowerPoint.
- You may find after you place an object onto a slide that you want to adjust its color. You'll have control over saturation which is the intensity of color. You could boost it or even decrease it to make a black and white image. Additionally you may want to adjust the color temperature. Essentially, the warmth or coolness of the object. Let's explore what options you have built in to PowerPoint. Let's go ahead and adjust the color for a few images. I'll start by selecting the image that I want to modify.
Simply click so it's active. Now go to the Format picture tools area and you'll see controls. Usually before I adjust color, I'll take a look at the exposure value. That's because if you brighten an image, the colors are going to become less saturated and if you darken an image, they'll become more saturated. This particular image needs a little boost to the brightness and now it looks better. I can simply twirl that closed and go down to Picture Color.
Now we can adjust the saturation and the color temperature. Saturation has several presets available so you can make the image more or less saturated. Now a jump to 200% is really pretty dramatic so you may notice that changing things really high values tends to produce some very artificial colors in flat areas. I find that doing smaller changes are much more effective. As such you'll need to key the value in using the input slider there or the text field.
Additionally, take advantage of color tone. You may recall our discussion of color temperature earlier, how shots could be warmer or cooler. If you go with the presets to the left, it's going to emphasize the bluish tones in the image and cool the shot down. This will change the apparent lighting conditions or the white balance. Feel free to explore those options. Let's go on to another image here and I'll select the photo.
The format picture controls are still available so this particular image just needs a little bit more contrast. I'll type in a value of 30% and you'll see that the black areas come through a little bit more. Let's combine that with a boost in brightness of 30% and we'll see how our shadows and midtones are doing. That's a bit much so we'll take that down to 10. You have to be careful when dealing with images that have a lot of contrast and bright areas.
10 looks better and let's try 10 on contrast as well and that feels pretty good. Now there's not a lot of color in this image but even shadows have color in them. Let's bring this out to a higher value. I'll try 145 and you'll see there that it brings out some of the tone. Now some of the browns and subtleties in the fur really come through. Conversely, if you're trying to make a black and white image, you can also pull the saturation down.
Either partially so that a bit of the color remains or all the way down to zero. I often prefer a reduced amount of saturation still leaving a hint of color in. If you decide that you'd like to, you can also take advantage of the Recolor box. These presets here are offering different ways to quickly apply an effect. You can go ahead and choose from different black and white options or sepia tones or apply a stronger color effect that applies the tones to certain areas.
These are more graphical in nature but do allow you to turn a photo into something that looks a bit more like an illustration or to something that's ready to screen back as a background or for a title slide. Remember, as you work with images, you'll want to pay attention to those format picture controls. Be certain that you are looking for areas of color that need adjustment. Now if you take this to very high values, well it may look appealing at first, you'll tend to notice a flattening of detail and that things start to look artificial.
Oftentimes what we perceive as a lack of color is really a lack of contrast. So try applying a boost to saturation as well as an increase to contrast and see if things don't look better. Usually a dab of contrast with a slight boost to saturation will improve images that have tough lighting conditions. Now if at any point you feel like you want to change your mind, you have the ability to select the image in question, go on over to the format picture controls and you'll find that you can reset things.
The fortunate thing here is that you can reset by area. So if I decide that I just want to change this back, I can click the reset button and all of the picture color controls have been removed. If you want to change just an individual area, simply go to the text field in question and type in the default value or you'll notice in the preset list that usually there will be a neutral position in the middle or a preset that doesn't have anything applied.
Again, there's the middle one with base saturation. From the recolor options, it's usually going to be the top left corner which will reset it back to the default. So you can either apply a global reset or reset the individual parameter.
