OPF Image Treatment

Side-by-Side

An image and content panel share the slide, giving visual context without sacrificing explanation.

side-by-sideNative OPF

Best Fit

Case studies, product explanations, before-and-after comparisons, and profile slides.

Photography Guidance

Use a photo whose subject reads well in a vertical crop. Keep the image subject oriented toward the text side when possible.

Avoid

Avoid side-by-side treatments when the image needs panoramic scale.

Treatment Practices

1

Use a clear 50/50 or 40/60 split and align content to the same grid.

2

Keep the crop simple enough to scan at thumbnail size.

3

Match image directionality to the reading flow.

General Image Rules

1

Crop with intent

Choose fit, position, and size based on the subject and message, not just available space.

2

Protect readability

Text over images needs enough contrast, an intentional overlay, or a separate text surface.

3

Respect image truth

Avoid filters or crops that distort evidence, screenshots, charts, or compliance imagery.

4

Keep a system

Use a small set of image treatments consistently so photo-heavy decks still feel coherent.
