Resetting a Photo
You cannot uncrop after compressing the picture (assuming you use the default compression options that include
deleting cropped areas of pictures). By default, saving compresses and makes crops permanent, so be sure to undo
any unwanted cropping before you save.
Resetting a Photo
Once the picture is in PowerPoint, any manipulations you do to it are strictly on the sur-
face. It changes how the picture appears on the slide, but it doesn’t change how the picture
is stored in PowerPoint. Consequently, you can reset the picture back to its original set-
tings at any time (provided you have not compressed the picture). This resetting also clears
any changes you make to the image’s size, contrast, and brightness (contrast and bright-
ness changes are discussed in the next section).
To reset the picture, right-click it and choose Format Picture to display the Format Picture
task pane. Click the Size & Properties icon (third from left), and in the Size section, click
the Reset button.
Adjusting and Correcting Photos
PowerPoint has some powerful features for adjusting, correcting, and applying artistic
effects to photos. Not only can you adjust the brightness and contrast, but you can sharpen
or soften an image, tint it, make it black and white, and apply several types of artistic
effects to it that make it look like it was created in some other medium, such as charcoal
pencil or collage.
Applying Brightness and Contrast Corrections
You can adjust the brightness and contrast for any photo in PowerPoint, and you can adjust
the sharpness or softness of the image.
Brightness refers to the overall level of light in a picture. The brighter the setting, the
lighter each pixel of the image is. Brightness does not affect the color hues. You might
increase the brightness on a photo that was taken in a dimly lit room, for example.
Contrast refers to the difference between the lighter areas and the darker areas of the
photo. Adjusting contrast makes the lights lighter and the darks darker. Increasing the
contrast of a picture makes its image more distinct; this can be good for an older, washed-
out picture, for example.
Sharpness/softness is controlled with a slider, with the default being right in the middle
between them. When you sharpen an image, the edges of the objects in the picture appear
more distinct; when you soften an image, the edges are blurred. PowerPoint fi nds the edges
