Photoshop Tutorial - Intermediate and Advanced Users
Note: Please brace yourself to "Have Fun" before proceeding

Here's a nifty way to make a presentation image from any image in your portfolio.
Use only one image, and turn it into a business card, web banner or any other
professional presentation you like.

With lots of options: using text, the move tool, clipping group, and layer mask,
you can configure your image anyway you like. (Also use the opacity slider -- I didn't mention that)

It's all about having FUN!
