I have a Canon T3 and I have taken some photos that I would like to submit for critiques. I have noticed that most if not all photos have a watermark on them. I assume it's to keep folks from reusing the photos and claiming them as their own.
I have a MacBook Pro with IPhoto. How do I put a watermark on my photos?
Just starting out and just using what I have available to me. If someone can help me, I'd be appreciative. I enjoy lurking and looking at everyone's fantastic pics.
