Really good but missing the following
Really nice app easy to use and free it's exactly what i was looking for I seriously recommend it. However i didn't rate it five stars as its missing the following:
1. It only works with full stops, so its missing the 1/2 & 1/3 of a stop.
2. It only works by adding only 1 filter at a time, so its missing filter combinations like adding the CPL with the ND filters.
Works but needs updating
I just opened the app and a box came up saying the app may slow down my iPhone and that it needs updating. Hopefully Thomas is still supporting it?
Awesome tool for us photographers in the field! I used to carry a piece of paper with conversions written all over it for long exposures, but now it's on my phone
