So I was kind of excited to get my new pokarized filter for my canon rebel xt. I have been using photoshop for a while. By no means am I an expert. However. How come my clouds and such don't pop with my filter? I take the photo and then it looks differet on screen than it does in the eye of the camera. Can anyone point me in the right direction for getting the contrast in the sky?

While we are on the topic of phography. I am slightly confused by the "converting images from raw?" Why would I want to do this? And how is this done? Simply by saving the Jpeg File in photoshop? If you could please Help me that would be great! Thanks..

You might need an ND filter for clouds to "pop"
Polarizers only polarize light, or usually glares.

Try adjusting brightness, contrast and saturation in your editing software to improve your shots taken with the polarizer. RAW gives a higher quality non compressed or adjusted photo. It also gives bigger dynamic range (12 bits instead of 8 bits) which gives more latitude in adjusting brightness after you've taken the shot. There's other forums that explain this in more depth or elsewhere on the web.

Polarizing filters have the greatest effect when shooting at 90 degrees to the sun (sun directly to the left or right).

Or reducing glare off things like ponds, windows, etc. Look here, scroll down to 'Taming Reflections', but the whole thing is instructive.

That's right. Not always convient, but it produces the best results.
