Solar Eclipse Sparks Warning About Smartphone Camera Damage

On August 12, a solar eclipse will cover up to 88 % of the Sun over Denmark, the strongest over the country since 2015. Astronomer Tina Ibsen notes that the intense light can burn smartphone camera sensors if phones are pointed directly at the Sun without proper filtration. Experts such as Professor Chris Flook and ophthalmology professor Geoff Bradford explain that most mobile cameras lack the protective filters needed for safe solar photography. They recommend using solar filters that meet the international ISO 12312‑2 standard, the same specification required for approved eclipse glasses, to prevent sensor damage and over‑exposed images.

The advisory highlights that newer flagship phones, with larger sensors and brighter lenses, are particularly vulnerable, and users of high‑priced devices could face costly repairs. NASA’s guidance on safe eclipse viewing reinforces the need for certified filters, warning that ordinary neutral‑density filters are insufficient.
