It's January 1st so it's time to reset the copyright notice in your camera(s) to reflect the new year, so your 2017 images will have the correct information.
Most digital cameras today, can automatically insert your copyright notice into the metadata of every image you make as they are stored. Each of my cameras have been reset this morning to insert “Copyright © 2017 NSL Photography. All Rights Reserved.” into every image I make.
If you haven't been inserting your copyright notice in your images, to date, to protect them, I suggest you consider start doing it today.
I'm often asked the question when I run workshops, or anytime I'm with enthusiasts and we're talking photography, “You're a pro, so I understand why you place your copyright on your photos, but why should I worry about it? I'm not selling my photographs, nor using them in my work.”
It's a great question.
