OPF Image Treatment
Circular Crop
A round crop isolates a person, logo, or object for a compact identity-focused image.
Best Fit
Speaker bios, team grids, testimonials, customer quotes, and people-centered case studies.
Photography Guidance
Use square source images with the subject centered. Leave enough headroom so the circular crop does not cut into the subject.
Avoid
Avoid circular crops for landscape scenes, screenshots, or charts.
Treatment Practices
Use consistent crop size across repeated people or customer cards.
Center faces and keep backgrounds simple.
Pair circles with concise labels, not long paragraphs.

General Image Rules
Crop with intent
Choose fit, position, and size based on the subject and message, not just available space.
Protect readability
Text over images needs enough contrast, an intentional overlay, or a separate text surface.
Respect image truth
Avoid filters or crops that distort evidence, screenshots, charts, or compliance imagery.
Keep a system
Use a small set of image treatments consistently so photo-heavy decks still feel coherent.
