Readable, one idea, honest
Contrast: text needs a contrast ratio of at least 4.5:1 against its background (WCAG). Light grey on white fails; so does blue on black.
Size: on a classroom projector, body text below about 24 pt is unreadable from the back row. Headings should be bigger still.
Load: one idea per slide. If a slide needs more than ~40 words, it's a document, not a slide.
Hierarchy: the most important thing should be the biggest thing.

This slide breaks three rules. Fix it until every check passes: contrast ≥ 4.5:1, text ≥ 24 pt, 40 words or fewer.
Results of our mapping project for the client
We flew the site three times over three weeks with the Matrice 30T at 200 feet and collected 412 images per flight which we then processed in DJI Terra to create orthomosaics and 3D models that show the progress of the building including the slab and the columns and the second floor deck which is about half done.
- Contrast 2.53:1
- Body 14 pt
- 66 words
