Can I leave a neutral intensity filter on
I bought a GS 400 panasonic video cam and 4MB Pixel camera
I am told that any one time ..only 1 filter should be attached to the video cam
I am taking outdoor photos /video all the t ime ; can I just leave the neutral intensity filter attached to the video cam at all times ?
2) I can then alternate that with the polarising filter when needed ; there's no need to get a UV filter .**

Why do you want to leave the ND filter on all the time? Its reason for being is just to cut down on light transmission.
The main purpose of using neutral density (i.e., ND) filters is to reduce the amount of light that can pass through the lens. As a result, if a shutter speed is kept the same, after adding a neutral density filter, a larger aperture must be used to obtain the same exposure. Similarly, if an aperture is kept the same, after adding a neutral density filter, a slower shutter speed must be used to obtain the same exposure.
Based on this understanding, ND filters help us in at least three situations: (1) reduce the intensity of light; (2) use slower shutter speed; and (3) use larger aperture.
Each filter we have in our collection has a specific use. Learning to "see" you finished product and choose the proper lens is all a part of the learning path we all must travel.
Hope this helps a bit.
