I chose Arie’s post about the tips she found in Photoshop. I used this blur effect tip in my Phantom of the Opera promotional poster. It made blurring things (making things look like they are in motion) so easy. It’d take hours for me to try and get this effect with a simple smudge tool, and it probably wouldn’t look half as good. This was a simple tip that with a few settings, could be tweaked… and it looked so professional. It could be used for a lot of different motion effects.
