I am in search / would love to have an app that would help me determine right exposure for my film photography.

I would address this to those who shoots nice (some would say vintage) cameras and film be it a Minolta, Nikon, Yashica, Canon, Fujica or Mamiya.

A nice light meter is always handy, but to be honest I do not have one. Some use a digital camera, DSLR to check exposure with difficult scenes to "meter" instead the film camera. Since I carry my Jolla with me, I would like to have an app with options to:

metering: This includes spot, and matrix, and average metering that is usually not available in older cameras. Since phone cameras are fixed apperture, exposure is controlled by their shutter speed. Some calculation and even user calibration (to the film used in the real camera) would be needed to show exposure options to achieve the shown image. I'd use this to nighttime photography, to check the right time for exposure, as well as checking extreme or difficult scenes.

exposure example taken with the Jolla's camera: Taking a picture with the camera or a series of pictures, that could be compared next to each other to help selecting the right shutter speed and apperture.

help me with some environmental data: temperature from weather forecast sunrise and fall times, golden hours from GPS data moonphase compass to show ... well, not north, but west and east

note taking and exif data logging: simple notes and exposure data to be saved with film counter numbering environmental notes saved with date, time and position

There are many functions that others could think of, please add Your ideas, and vote up if You want to encourage experienced programmers. Thanks

I'm shooting digi, but anyways a light meter app might be handy. Don't know how precise Jolla might be, but a nice idea anyhow, worth to try.

As long as You make the app for a specific camera, it should be precise enough.

Don't forget to add a selection table for the film type you are using.

Different films have different reciprocity curves and on long exposures you have to factor in the reciprocity failure rate :)

(Oh My it's a long time singe I shot film but I used to buy B&W strip in 25m spools and roll it in my own cannisters, pretty short lenghths each, about 60cm to a roll so when I went to darkroom after shoots it was easy to handle the film for processing...)
