This is a brief excerpt from PhotoFocus
A popular trend these days is to sign your images when posting online. The thought is to treat the image more like it was being shown in a gallery and less like pixel dust in the wind. The process is really pretty easy to do. I’d also like to state that this is a much more attractive way to watermark a photo.
Here’s the process for Photoshop Users
Sign your name… take your time and give it a few tries. If you’re using pen and paper, go with a thicker felt tip pen or marker. If using a tablet, that works too. Be sure to create a nice large signature so you’ll have plenty of pixels to work with.
Scan or digitally capture the signature at a very high resolution. You’re likely adding this to high-resolution imagery, so better to start large and scale down (instead of up).
Clean up your signature with a Levels adjustment to make the whites and blacks crisp.
Save two versions of your file. One black on white and one white on black. You can choose Image > Adjustments > Invert to make a negative image.
When you’re ready …
