I'm trying to create an application similar to this for a school project: https://play.google.com/store/apps/details?id=com.reidwolcott.expocalc&hl=en
However whereas the application linked above shows aperture and ISO I only wish to have Current exposure, EV adjustment and Equivalent exposure.
Basically the user will be able to pick their current exposure from this list of shutter speeds: 1/8000, 1/4000, 1/2000, 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, ¼, ½, 1 sec, 2 sec, 4 sec, 8 sec, 15 sec, 30 sec, 1 min, 2 min, 4 min, 8 min, 16 min, 32 min, 64 min, 128 min
Then if the user selects +1 EV the equivelent shutter speed displayed is 1 down from the current, e.g 1/125 current would be 1/60 equivelent If the user selected +2 EV the equivelent exposure displayed would be 1/30. And so on and so forth.
I am very confused about how to go about coding this concept, if anybody willing to help me out I'd be hugely grateful!
I know SO isn't meant to be a free coding service but I'm just looking for some advice on where to begin.
