I use Pocket Light Meter for my meterless 35mm and 120 cameras. It's free and works quickly. I might try some of the other options. Normally use a Minolta IVF, but Pocket Light Meter is pretty darn close to being accurate. It's definitely helpful in a pinch. I don't trust it in low light situations, however.

I have been using the light meter app,
But my problem is it only has f8 and my lens is f7.1
My ilex shutter is also of odd increments

Does any one have the same problem and a work around solution

Any one know of a colour dev app?

You can modify an existing one into anything you want. So just use the info from particular color developing kit you are using and enter that into massive dev chart.

Hey Moderators!

There's a lot of good information in this thread, and there's going to more, and it's going to evolve. Maybe someone could be enticed to make some kind of wiki page for the info area of the site.

Has anyone done a close comparison between their spot meter and pocket light meter? I'm interested in how accurate the app is, and how well it handles low light.
My trusty honeywell/pentax gave up the ghost. And the world keeps bugging me to get an iphone.

Paul, I have not done any formal testing of the Pocket Light Meter app (https://itunes.apple.com/us/app/pock...381698089?mt=8), but in a quick comparison it was very close to how I would meter the scene with a Pentax digital spot meter. But it's different from both an incident and spot meter. It seems to rely on the camera built into the iPhone for the metering. Meaning you choose the focus point and the camera adjusts the image to "correctly" expose the subject behind the focus point. The app then gives you reading in EV or time and aperture. So you sort of need to use the preview image to see if it looks correct. It seems to work down to about EV 1.5.

I imagine one could get used to this type of metering and use it successfully as a primary meter. I'm not giving up the spot meter for large format, but I do like iPhone Light Meter app for a backup, or when i want to take out a small folding camera without a meter.

I also like the Reciprocity Timer (https://itunes.apple.com/us/app/reci...459691262?mt=8) app.
