I like the look that a polarizing filter gives, but I don't own one. I saw that Michael Seneschal was trying a demo version of Adobe Lightroom. Since it seemed easier to use than Photoshop, I thought it may be more my speed so I thought I'd give it a try.
This is taken with a plain jane Canon PowerShot S5 IS, but adjusted in a demo version of Lightroom to bring out the contrast in the clouds and ice. If you compare the before and after shots, I think it gives the look that a polarizer was used.
