EXIF Tags List

A description of possible EXIF tags used.

Exif TagDescription
ApertureValue The actual aperture value of lens when the image was taken. To convert this value to ordinary F-number(F-stop), calculate this value's power of root 2 (=1.4142). For example, if value is '5', F-number is 1.4142^5 = F5.6.
Artist
BrightnessValue Brightness of taken subject, unit is EV.
