I'm looking for an app that allows me to calculate long exposures as I am interested in night photography. I shoot Provia 100 or 400 and T64 mainly but also Velvia 100 and Tri-X (varying in 135 and 120). I've seen a few different ones like these but perhaps there are more and better?

Film Timer (which I believe was written by a member here?)

Reciprocity Timer
https://itunes.apple.com/us/app/reciprocity-timer/id459691262?mt=8

Long Exposure Calculators
https://itunes.apple.com/us/app/long-exposure-calculators/id547000247?ls=1&mt=8

Thanks for any insight into this app jungle

I've always used Pinhole Assist and it's been great. It has curves built in for a lot of different films, allows you to import your own curves, and meter from within the app or import EV numbers from a different meter. Gives you the straight exposure number and the exposure compensated for reciprocity.

Thank you for the quick reply, that seems to be an interesting app. It seems the developer also makes an app called Reciprocity Plus. I guess Pinhole Assist doesn't include as many films as Reciprocity Plus?

That's one of the downsides of apps -- compared with buying Office Pro for $500, apps are like pocket change. So I now have several of those mentioned above, but haven't really done much with them to evaluate them. The intent is I will "one of these days," but my primary interest being my annual Worldwide Pinhole Photography Day expedition, and hey, that's weeks away!
