★★★★★
Amazingly useful and always working, really like the updated usability. Just needs a bit more filter factors up to 11 stops if possible, as well as the countdown timer for the corrected time, then it would be truly amazing.
★★★★★
Easy to use and has an integrated timer that makes shooting very easy. Have gotten some great exposures with this app.
★★★★★
I can't speak to the results of the exposures given as I have just started using it. I do wish the filter adjustment was in stops rather than factor - or just an option in the settings.
★★☆☆☆
Very limited film database, doesn't even include Kodak Ektar, or many other colour films, if you want to shoot long exposure colour, find another app
★★☆☆☆
A simple check against a calculator showed up an obvious error in the final calculated exposure time. The reciprocity time is added to the original time rather than replacing it, use this and you'll be over exposing your images! I'll stick to doing this with a calculator
★★☆☆☆
Sadly this app crashes whenever I select anything from the menus. looks like the best reciprocity timer on Android but can't be fully used.
★★☆☆☆
On a velvia 50 any number of seconds larger 40 there is a error that no
data from the manufacturer for exposure so long! And app do not calculate!
But you using the formula fom the journal, where is the manufacturer
enabled when it is disabled? I still rely on my tables for night shots ((
spinning wheel is bad, there is no direct input (write your own or leave a
field) plus I want another input field here for a minutes, why I must
calculate second in mind?
