Exif Data - what do the #'s mean?
Posted: 2008-05-23T20:55:04-07:00
Is there somewhere that maps out what the values of the different Exif data rows mean?
Consider the following (which I copied from another post):
For example, where it says: exif:MeteringMode: 2
What is 2? Is there somewhere that describes the different values? (Not just the metering mode, but the rest too such as the light source, flash, etc.)
Thanks,
