I am not new to photography, but this seems to be such a basic question so I am posting it here. (maybe it is not so basic since I never thought about it until now )
What exactly is the publication date for a photograph? When the negative is processed? When the shutter is pressed? When the first print is made? When it is posted online? Used in advertisement? etc I am guessing the real answer may be complex due to new technology and old laws.
This is specific to copyrighting photographs.
I am organizing some of my old negatives that I didn't like so much when I first took them, but now with the filter of time, they are looking pretty good to me. I am planning to register the copyright, but don't know how to sort them by year for a "group".
Thanks in advance for any input!
