Format the Pictures

Some of the pictures from space have a black background. However, the density of the black is not as dark as the black color of the slides. There is a simple way to make adjustments.

Try it: Adjust the Contrast

Click once on the picture to select it.
Go to the Format tab.

Adjust the Contrast.

 

Brightness bathes the image in light and “washes out” the colors.

 

Contrast accentuates the difference between absolute black and white. When you increase the Contrast, the black gets darker and the white gets lighter. When you decrease the Contrast, the picture fades to grey.
