Awesome Eric. Hope it works well for you!Originally Posted by Eric Bryan
The app currently supports the following films. There are one or two obvious omissions - Astia, Provia and Portra for example - this is because all my research indicates that reciprocity is of minimal concern with these or I have simply been unable to find useful data.
The Tri-X times the app determines have been found to have some issues in the current release. These have been resolved and times that more accurately reflect Kodak's official data will appear in the next version. Along with a few other enhancements. I just need the time to complete it!

Tried to use it yesterday. I was disappointed that the apertures stopped below what I wanted to use. I was wanting to use f/128 but when I realized I couldn't, I just opened up the calculator and figured out my exposure on my own.
Hi Michael. I'm not sure I understand your issue. The app does not have any apertures in it. Can you give me a clearer idea of what you were trying to achieve in case it's an issue I need to address in the program?
Thanks!
Wait I thought Acros 100 was supported? Has this changed? It's specifically what I use for long exposures because it has such good reciprocity characteristics and use it when I shoot 10 minute to 4 hour exposures... Thanks!
I guess I am using a different app called 'Reciprocity'. Let me download yours and check it out. Thanks!
EDIT: Oh yes, your app is much better. Well worth the price. Thanks!
My understanding is that Acros has virtually no reciprocity up to 2 minutes and was then add 1/2 a stop. Does that sound correct? If so - I will add it in the next release ...
:-)
You are correct that it has no failure for 2 minutes, but I don't know after that, but the PDF for the film as the reciprocity chart in it (all the fuji pdf's seem to have it.
But I'm no good at math so having a chart would be great help after the 2 minute mark, right now I just "guess" lol
No worries Stone. Just PM me the chart you have and I'll see if I can do the math and include it in the next version. Be aware though that all reciprocity math after 2 mins is a bit sketchy as a film's characteristics may start to increasingly deviate from the expected math. If that makes sense!
I used this app yesterday when I was shooting a beach sunset. My stopwatch is in the shop for repairs, so I found the included timer on this app to be super useful.
Just wanted to say again, this is a kick-ass app and I've been sharing it with all my film friend
