Exactly what I was looking for – Exposure-Calculator Review

I have begun shooting IR with a Fuji X100T/Hoya R72 and needed an app to quickly let me calculate exposures based on a quick wide-open, high-ISO test shot. (Shoot at f/2, ISO 6400 to get framing/exposure locked down) Once I have this base exposure, I want to calculate new settings at a smaller aperture and lower ISO values. This app does exactly that in a straightforward, one-screen interface. You set your base exposure at the top of the screen, select which setting you want the app to calculate (shutter, aperture or ISO) and set the two remaining settings where you want them. So when I want to keep my f/2, 6400 exposure the same at f/8 and ISO 200, the app figures out the shutter speed for me and even offers to send push notifications when it's time to end the exposure. Exactly what I needed, presented clearly with no distractions. Five stars.
