Photometer

Its a nice start to an a phone based light meter but needs some enhancements adjustments. 1) There is no flash meter setting so you can measure flash power to set your camera. 2) Only supports front camera , not rear camera, which if you are trying to read a light meter you want it facing you and measuring light from the direction you are shooting; preferably general light vs a specific point perhaps which this only measures on a forward facing point...and usually at least for me at really low

I have looked at many light meter apps, and this one has by far the best handling and visuals, but it tops out at 4 second exposures, which renders it mostly useless to me. Please fix developers!

Nice interface but minimum aperture is f32 - not useful at all for pinhole work. Also only full stop increments allowed - no half or third stop settings Would probably be a 4 or 5 if these were addressed Update response to question - f128 - laser cut pinholes

I use this with medium-format film cameras, where it does a very good job and has saved me from purchasing a dedicated light meter device. It has two views; modern and classic. The classic view presents the interface of an old Gossen or Sekonoc meter - a bit of a gimmick. The modern view provides a full-screen view through the camera with a spot target, RGB color guide and controls that are very readable and intuitive - it's what you'd want if you bought a dedicated light meter.

Those who ever used an old school Light Meter will feel instantly familiar with this app, the classic view matches my Hasselblad 500C perfectly. The modern view is super simple and intuitive.
