Backgrounds set the tone before anyone reads a word
Viewers form an impression of a presentation's quality within the first few seconds, often before they've read any text on the slide. A background that matches your brand colors or the tone of your topic does a lot of that first-impression work quietly, in the background.
Keeping text readable over an image
A busy photo background can easily swallow your text if you're not careful. Lowering the image's transparency, or layering a semi-transparent solid color fill on top of it, keeps the visual interest while making sure your text stays legible.
Frequently Asked Questions
My background photo is too dark and the text is hard to read β what do I do?
Use the transparency slider in the Format Background pane to lighten the photo, or add a semi-transparent solid fill on top of the image so the text stands out clearly.
Can different slides have different backgrounds?
Yes β simply don't click "Apply to All." Set a background on each slide individually, and each one keeps its own distinct look.
