Here is a comparison of the metadata I was able to retrieved from digital photographs taken with two smartphones and two digital cameras.
The following metadata details apply to all of the photos:
File type: JPEG
Colour profile: sRGB
Colour depth: 24 bit = "true colour" = 16,777,216 available colours
For your reference:
1000 bytes = 1 kilobyte (kB)
1024 bytes = 1 kibibyte (KiB)
1,000,000 pixels (px) = 1 Megapixel (MP)
millimetre (mm)
second (s)
I have listed how many colours each photo contains. That data is not saved in the metadata but was simply an interesting statistic one of my photo editors provided.
At the end of a community camera club meeting we were given the homework challenge to go forth into the world and shoot some portrait photos. Well that is easier said than done. People tend not to cooperate when I attempt to take their picture. Even the birds and dogs in my neighbourhood suddenly become camera shy when I point my lense in their general direction.
