My favorite magazine by far for photography is Digital Photo from the UK. You can find it at Barnes & Noble for about $11.50. I know that sounds expensive but it is an incredible collection of photography tips, post processing techniques, equipment reviews and more. PLUS, it has a CD included with video tutorials, the start files for their projects in the magazine so you can follow along… and always a folder full of something fun. It might be textures… or this month are 5 displacement filters (don’t worry about the name, just use them!) to give a nice reflection in your image.
Just tried their reflection technique quickly (see below) I have the Flood filter from Flaming Pear which is also good… but this is worth trying.
