Your lecture is on your camera roll. Now what?

You take 40 photos in a two-hour lecture. The slides, the board, the extra example the lecturer drew in the corner. It feels safe. You have the class in your pocket.
Then you never open the album. Or you do, and you scroll like it is Instagram. Recognition again. No recall.
A photo is a source, not a session
The camera is great at capture. It is terrible at telling you what matters. A full slide deck on your phone is the same problem as a 40-page PDF: too much, no questions, no schedule.
Use the photo as raw material. The study session starts when you pull one idea out of it.
What is worth photographing
- The slide with the definition, formula, or process you will have to say later.
- The extra example that is not in the PDF.
- The board sketch that only existed for five minutes.
- A textbook page with a table you always mix up.
Skip the title slide, the joke slide, and the page you can download later. If the photo is blurry, retake it now. A fuzzy formula is useless at 11pm.

Make the photo usable in 30 seconds
Crop to the content. Turn the page so the text is upright. If two ideas are on one photo, that is fine. Do not spend ten minutes editing. You need readable pixels, not a portfolio.
In Quiz Genius you upload that photo and the app builds a study set: flashcards, a quiz, and notes you can skim. You still cut junk cards. The win is that you start from the lecture, not from a blank note.
A 10-minute loop after class
- Pick 3 to 8 photos from today. Not the whole semester.
- Upload them while you still remember what the lecturer stressed.
- Generate the set, then delete cards that quote a whole slide.
- Do one short flashcard pass the same day.
That last pass is the point. The photo got you the source. The card tells you if you can say it without looking.
Common mistakes
- Shooting every slide "just in case" and never processing any of them.
- Studying by zooming in on the photo. That is rereading with extra pinch gestures.
- Waiting until Sunday to upload 90 photos. You will not.
If you have three decent photos from this week, download Quiz Genius and make one set tonight. Ten minutes. Then put the camera roll away.
