PowerPoint is wonderful for creating dynamic presentations to deliver data for training, meetings, annual reports and much more. In the past PowerPoint has been limited as to how much you can alter images but has several new features that are quite nice if your don't have access to professional photo correction software, or don't have time to wait on your graphics department to prepare images for you.
Images are a big part of PowerPoint but finding the pefect image is often a difficult task. Some new features that can help correct minor flaws are Contrast And Brightness. Sometimes Sharpening a picture can make the details pop a little better without making them look over blown.
Change the Contrast of an image
- Select the image on the slide
- Click the Picture Tools Format tab in the Ribbon. (This tab is context seneitieve and may not display unless there is a picture selected on the slide.)
- Click the Corrections drop down and point to the options below Sharpen/Soften. The Center selection is 0%. Moving to the options right of center sharpen the image and moving to the left of center softens the image. Choose the best looking corrections for your image. In this example the image on the right has been Sharpened 50%.
- You can adjust Brightness/Contrast from the same drop down menu. Adjusting Brightness/Contrast needs to be done as a second step but is often a good follow-up action for images that have been Sharpened.
Another aspect of images that can be modified in PowerPoint is the color. Sometimes the color of the picture does not match the rest or your presentation theme, but the content is correct. A simple way to get around this is to experiment with color options for the image to add a special effect or desaturate the image to distract from the fact that the colors don't work well together.
Change the color of an image
Select the image on the slide.
Choose the Color drop down menu
Select from Color Saturation, Color Tone, or Recolor options. In this example the original picture is in the upper left corner. I have chosen 3 variations. Upper right is Color Saturation, lower right is the Color Tone option. B
y changing the temperature of the colors in the image you can make it seem like a different season or help dial back color in images that are slightly over blown. The image in the lower left corner is using the Recolor
option which can change the Hue of the image to match Theme colors in your presentation.
If the options for Recolor do not match closely enough you can use the advanced options under Color to see more variants and use the eyedropper tool to select the color you want. (Shown below)
- From the image above you can also select the Picture Color Options from the bottom of the Color menu which displays the Format Picture dialoge box you see to the right. This will allow you to change Saturation or tempurature settings to customized specifications. Choose from Pricture Corrections, Picture Color, or Recolor settings that have presets or allow custom settings to be applied to one picture. If at any time you do not like the settings you have chosen you can simply click the Reset button at the bottom of the dialoge to reset to the original image.
I hope some of these customizable options will be helpful in taking your presentations to the next level and will enable you to make adjustments without needing the assistance of additional graphics software.
