Want to try something cool. I don't have any filters and I want to try and better understand what the difference is and so I was thinking why not ask the experts. Here is the deal:
-Post pictures of the same image with different filters in this order.
-Polarizer
-ND
-UV
-IR
If you do any post processing make sure that you do the equal amount on all the others so that the results are measureable. I would do this but unfortunately I don't have any yet. Hmmm hopefully this will produce some kewl results.. be creative :)

Wow, that's quite a lot of effort, and I don't think there's much artistic merit to it. Good luck finding people for your challenge. |

As the filters have their different uses most people won't use varying filters on the same scene. Websites that offer filter kits sometimes have images showing the difference with the kit filters. I believe b&h has some of these kits.

This is really a pointless exercise; each filter is designed for a specific purpose, and it makes no sense to shoot the same scene with each of them in sequence, most of them will not apply to a given scene.
What they are used for:
1. Polarizer is used to cut down reflected glare, and when applied to the sky at the correct angle from the sun it deepens the blues dramatically by cutting down the refracted light in the atmosphere.
2. UV/Haze filter is used to cut through atmospheric pollution. In theory, our sensors already do that for us. Some people use this filter, which is visibly transparent, to protect their lens surfaces.
3. ND filter is used to reduce light across the entire spectrum and allow longer exposure times. Graduated ND filters are used to reduce the light from a portion of the scene, typically the sky.
4. IR filters block most of the visible light and allow the infrared range free passage; they are used with infrared film primarily. Current dSLR cams don't work well in the infrared range, although there are hacks to remove built-in limitations in the sensor filtering. There are some earlier point 'n shoots that were fully sensitive to infrared light, and they work very well with this filter.

Thanks bear that is good information, much appreciated. I see your point about purpose vs. the use of in the same image. I guess I was hoping for someone to break the rules. :) Its kewl either way... I am sure at some point there is a good shot that has the potential for all those filters, but I might have to be the one to find it someday :).
Thanks everyone
