Discussion prompts
- Predict first: the phone folds up boxes that are the same color. Which shrinks more — a plain sky or a confetti photo? Why?
- Predict first: if you added one stray red pixel into the middle of a long blue row, what would happen to the count of tags?
- Real photos still send fast even though they're busy. Predict how — what do you think the phone gives up to make that happen?
Where it shows up in real life
- A photo that's 'too big to text' until the phone compresses it
- A plain screenshot of a webpage that saves as a tiny file
- A detailed nature photo that stays a big file no matter what
