Software no longer supported EDIT: The dev responded to a recent inquiry and stated this app will no longer be developed. If you have issues, you may not get a resolution. This was a very effective app for me when it worked. -- None of the radio buttons work on my 2014 Moto X. Tested across two .models on 4.4.4. Any help from the Dev would be appreciated. 3-starring because the app worked well in the past.
Useful for ND filters Exactly the app I've always wanted to write. Exposure in, equivalent exposure out + configured stops. I don't see any issues with changing iso like others describe. The app does round unnecessarily when you are already well into bulb mode territory, but the difference in actual exposure is mostly negligible. Would like to see enhancements as presets for filters
Excellant Exactly what I was looking for. Just wish it would go above 9 stops diff. Why? I have a 9 plus 4 so I compose the shot with no filters and take a reading and then I want to know what the speed would be if I added the 2 filters stacked together. Currently I have to work it out manually or add the 4 then take a reading then use the calc then add the 9. Would like the flexibility to specify 13 in the calc.
Not calculating correctly!! The interface is great and exactly what i'm looking for, but it does not calculate correctly. If you decrease ISO, it will also increase the Fstop# (decrease aperture size). This is the opposite of what should happen. If you decrease ISO, your aperture should get larger, not smaller (should lower Fstop#).
Great! Exactly what I needed; bought some film to try out this great lens that I have for my old Canon A-1. I don't have a light meter, and I don't trust the built-in one, so I'll be using my digital EOS for light setup and metering. The widest aperture on the lens on the EOS is 5.6, the widest on the old lens (a 135 mm fixed length) is 2.5, and, being so used to all the automatic settings on the EOS, I'm slightly out of practice when it comes to exposure converting. This is gonna save me a lot of pain, thanks!
Great app. Very flexible. A must for ND110 use Just wish I'd found this earlier - simple and effective once you understand what it's doing and really useful when using strong ND filters. Those reviewers marking it down because it stops at 9 stops don't understand how it works - look at the equivalent exposure and you'll understand. By default I think it uses a current exposure of 30secs - when you go to +9 stops adjustment this becomes 256 minutes of equivalent exposure! If you went to 10 stops this would be 512 minutes (are you really going to stand there with the camera in Bulb mode for 8 hours?). Once the current exposure is set to something more reasonable (e.g. in most conditions you'd likely be at 1/30th or above) you can then dial in 10 or more stops adjustment (I.e. the app is placing an upper limit on the equivalent exposure of 256 minutes).
