Hello, all! I'm not exactly a photographer (though I am a shutterbug!) but I do have a question raised to me by a friend of mine on the subject of watermarking photos. She's working on starting a photography business, and she watermarks ALL her pictures--even the ones she gives out to her clients. I'd never heard of doing this before and I told her I thought watermarks were great for posting work online, but when a client purchases a picture they pay for the picture, not for the picture with advertisement. To be fair to her, while the watermark is obvious it isn't obtrusive. So, is it normal for a professional photographer (or an aspiring professional!) to watermark ALL their work, even the digital prints that a client buys? (I'm hoping I'm right on this one, but only because I don't want to eat humble pie when I go back to her if I'm wrong ) Thanks!!
