"Simple Exposure" Meter

This app will turn iPhone into exposure meter for cameras.
It calculates the EV value at the present moment based on the photo taken with the built-in camera of iPhone and displays the combination of preferred ISO vale, F value and shutter speed.
It also writes each original value set (ISO, exposer, shutter speed) on the photos taken with iPhone and views as a sample.
It also writes each original value set (ISO, exposer, shutter speed) on the photos taken with iPhone and views as a sample.
The range of ISO vales, F values and shutter speeds.is as follows.
ISO vales:
- "25","50","100","200","400","800","1600","3200","6400","12800","25600","51200"
F values:
- "F0.7", "F1", "F1.4", "F2", "F2.8","F4", "F5.6", "F8", "F11", "F16","F22", "F32"
shutter speeds:
- "60","30","15","8","4","2","1","1/2","1/4","1/8","1/15","1/30","1/60","1/125","1/250","1/500","1/1000","1/2000","1/4000","1/8000"

NOTE:
However this app calculates ISO vale, F value and shutter speed based on the photos taken with the built-in camera, we are not able to guarantee the accuracy of these values.
