I once bought a second-hand film camera, but the built-in light meter was broken. Then I started to build this lightweight light meter for all film photographers. A simple UI with a very hard-core, statistic-based, lux calculation inside. The only light meter you will need on the go. After a dozen months of absence, I am back and redesigned the whole UI from scratch, bringing back great skeuomorphism time. Don't miss out on this amazing opportunity to enhance your film photography journey with LightMeter35 2.0! Download the app now and join our growing community of analog lovers. Experience the magic of capturing moments on film with the most reliable and intuitive light meter app on the market.
