What do you use to make the watermarks on your photos?

Several people have asked me that question: What do you use to make the watermarks on your photos?

To create the semi-transparent watermarks on my photos, I use Photoshop. I created custom "actions" and "droplets" (i.e. scripts that automate a series of commands) to add various layers with the watermark, using appropriate blending modes to give the semi-transparent effect. But creating those scripts this is quite complicated and require a very good knowledge of Photoshop layers, blending modes and scripting, so I do not recommend this approach unless you are very good with Photoshop.

The good news is that there are web services that can add watermarks on your photos for free, like http://www.watermark.ws or http://picmarkr.com . Those probably work pretty well in most cases, so you should try them. I am sure there are other services like those, just google "watermark online" or "online watermarking".
