        "note": "Exposure value EV = log₂(N² ÷ shutter), where N is the f-number — it pins down the aperture/shutter combination, and every one-EV step is a 'stop' (a doubling or halving of light). EV100 normalises it to ISO 100 by subtracting log₂(ISO/100), giving the scene brightness the meter saw: bright sun is about EV 15, a typical interior EV 6–8. Equal-EV settings give the same exposure — the basis of the exposure triangle.",
