1. Given an exposure (Aperture, Shutter speed, ISO), allows calculating equivalent exposures - set 2 new parameters (a combination of Aperture, Shutter and ISO) and the 3rd parameter is automatically calculated.
2. This switch simply selects how a small set of shutter speeds around 1 second are displayed, choose the one your camera adheres to.
3. Exposure calculations work for all camera makes, this switch is simply for display purposes.
4. Note: in the Shutter settings section there is a switch tor camera type.
5. It is also possible to add up to 3 ND filters of up to 30 stops each to the calculations, handy for those long exposure photographs to blur water and clouds.
6. The app also includes a timer for exposures of 4 seconds or longer.
7. Please contact me if you'd like to help translating the app into your language.
1. EDIT: Thanks for the responses, I see it's strictly for stopping/ND filters but seems like it could also be a lightmeter (maybe) if you allowed deselection of the fixed stop radio buttons (or with small tweaks) and that it could be a more versatile app for certain.Used this for some night time shooting and the settings worked as hoped.
2. Here you can take a test shot without Filter in any ISO or Aperture and then you can calculate shutter speed values as per your ND Filter as well as with any desired new values of ISO or Aperture.Great FREE app.
3. Instead of guessing how many stops are necessary for that particular exposure, I can bring along a camera where I can determine correct shutter speeds based on the histogram.
4. I am not sure that the app gets the exposure right first time, but the light was changing and my test shot was probably a little off.
5. I'd like to request one feature that I couldn't find though: separate 1/3stop ; 1/2stop ; 1stop options for 'new exposure' section of the main calculator.
6. I can get it right first time out.[Jan. 23 2020 Update] This is the best ND long exposure calculator that I have ever used.
7. I fly drones and when I manually set frame rates and shutter speeds to 30fps and 1/60, I have to use ND filters.
8. only downside is it doesn't have landscape mode as im unable to see shutter amounts when going beyond 1/80 as its cut off on screen.
9. Perhaps it's not compatiable with SS G20 but I played with the settings and could not get a reading giving me a shutter speeed anywhere close to my Sony, it was well off 1/4 vs 1/30.
10. For calculating between lenses with different aperture scales.Won't give a strict reading based on just iso and Fstop.
11. I also greatly appreciate the developers time and effort for continuously updating this app that I have been using for years.
