A light meter is required for traditional photography. Normally I use a
handheld light meter, but sometimes it would be convenient to use the built-in camera in my phone as I always carry my phone with me.
This app uses the built in camera of your android phone to measure exposure value. The app includes settings for filter correction and calculation and correction for bellows extension (for Large Format cameras).
***** NOTE ****
HTC phones are not supported - sorry but this is a HTC hardware issue as HTC doesn't use EXIF data in their camera. PLEASE don't leave a rating if you have a HTC phone.
PLEASE DO complain to HTC to have HTC include EXIF
