Do you need to copyright your photos, and announce that copyright with a logo? I am not a lawyer, so check with a local legal source. But I do know a little about marketing. And about how images are often, um, “borrowed”. See the post of a couple of days ago about Google Image Search.
I usually do this:
I.e. a small logo on the image, often (but not always) with © sign.
And about those signs:
- The © sign on your photos makes it look a little amateurish, but in some environments (on Tumblr, for example) or categories (like photos of celebrities) I find it necessary for extra clarity. My photos are copyrighted even without the © sign, but it does stress the point.
- The ™ (Trade Mark) logo is something you can and should add to your marketing names. As in “The Willems 400-40-4 rule™”.
- The registered trade mark sign ® may only be added if you actually registered the trade mark with the appropriate authorities.
- Do embed your copyright information (“all Rights Reserved” and author name in the image’s EXIF data.
Photography is a business and it pays to treat it as such.
