I have used both and can detect no differences except $$$.

I usually shoot portrait, sports action, and birds, all of which benefit from a narrow DOF. I am looking for suggestions for shooting large group photos (50-100 people) sometimes in lower light conditions. Info from experienced photographers on Aperture and Shutter priority are greatly appreciated. Thanks

Thanks for this. So, the best protection is to not post good images on the Internet!(e.g. Facebook)......and therein, lies the dichotomy. I am a serious amateur who enjoys capturing the occasional nice pic. But, it's unlikely that I would go through the "wickets" to pursue photo creds or $$. One of life's injustice's. Oh well, I still have some pretty good shots of my grandchildren and family!
Happy Holidays, everyone!

Does each individual image have to be registered or just the copyright name?

Also, is the artists' unique copyright logo reqired on each image posted?

How do you register for a copyright?

Can you elaborate on establishing the copyright process for pictures?
