Photographers and designers merely create. It’s up to the consumer to enjoy what these creators have prepared for them. Now, there comes a time when people would rather steal images than purchase them rightly. There’s also the moment the creator realizes he’d much rather have his name on what he’s made so that the world knows. This is why artists sign their work and photographers and designers add copyrights and watermarks to things. Doing so in iPhoto isn’t possible (though you could download Picasa for free). What you really need, though, is a dedicated app.
Watermarker, developed by Reactiv Code, is a nice-looking solution. It’s simple, has all the features you need, and doesn’t cost nearly as much as Digimarc. Sounds promising, right? Let’s find out if it really is that good.
