The best of the best and so accurate!

I am a professional photographer and Director of photography working on both coasts, so as you can imagine, I am constantly in need of a check for exposure in between shots and set ups, and although I do have my trusty spectra, pro light meter, being able to check and double check, my readings with this app makes my life much much easier!

If you’re wondering whether this is worth the subscription price, then I ask you aren’t you are perfectly exposed shots virtually priceless???

I found this app through Reddit and I’m so impressed!! I can’t afford a nice light meter and this app has never failed me. Super easy to use. At this point I don’t even think I’ll buy a light meter! Can’t recommend this app highly enough

The best and most accurate

I have now tried this app for my Leica MA, it just works like a charm. You can have different profiles for different cameras, and lenses. I have shot 5 rolls of portra 400, exposure is on point using this app. Definitely worth the money.
