Hi, I'm kinda new to camera filters but recently bought a UV (clear), CP (circular polarizer), and a Neutral Density (ND) filter. I hope to use them in my future videos. Could someone tell me when I should use each one, like certain situations. Also, does the UV (clear) filter degrade quality of the picture if left on all the time (to protect the lens)? For testing purposes, I made a little video for all to see and prehaps might help other in the field of filters. I compare the picture w/ each filter. Grab the video from:

Oh Great! My day has gotten worse!I just screwed on my wide angle lens to the UV filter which is screwed onto my camera and now its stuck on! I can screw off the UV filter from the camera, but the filter is stuck onto the WA lens. I been trying for the past hour to get it off, using rubber gloves, towels, bare hands, and even pliers. I can't get the damn thing off! Help! ------------------

You made a good choice buying those particular filters! But you would think that one would know what each filter does before making their purchase... Anyway, You can keep the clear UV filter on as much as you want. It wont degrade the picture. The polarizer is a must have for eliminating glare and reflections when shooting through a window. They can do some other wonderful things too like seperating clouds from the sky so they "pop" real nicely. What level ND filter did you get? .3, .6, .9? Those are common ones. It should say on the side of the filter. .3 knocks your exposure down by one stop, .6 by two, .9 by three and so on. You use them to handle exposure issues or to increase your depth of field by allowing you to use a higher f-stop.
Be careful when sandwiching more than one filter together and be sure to use some type of lens shade so you don't get any funny reflections on or in-between the filters. Have fun and experiment!  |

uh oh!  The threads on those filters are small and easily damaged! Are you sure you got the right size filters? If you can't get it off without damaging anything else I suggest you bring your lens to a camera repair shop. |

My ND level is .6Yes, the sizes are all correct, 37mm. Still can't get it off. Will probably have to goto a shop. How does a lens shade attach to a camera (I've seen them before) and is it really needed? I hope not had any weird reflections.  ------------------
