simple but important question on filters

[ulrichsd]

I have two filters, a UV 1x, and a Skylight 1A.

Could someone please tell me difference between the two and a recomendation on when to use them? The camera manual recomends use of the UV filter outdoors since Kodachrome is tungsten-balanced film. I've heard people say to leave the UV filter on all the time as a lens protector. Should you ever use both at the same time?

Thanks in advance,
Scott

I'm not exactly sure. I might not remember this correctly.

UV is used on overcast day, but I forget if that's for video or film.

Skylight I believe is really just for protecting the lens, although I remember having a perception or belief in college that it ever so slightly "warmed" the tones.

I'm curious what others think.

Alex has it..the 1A and the uv basicly do the same job..because film emulsions pick up ultraviolet light..that your eyes don't..the uv filter is clear to light yellow..the 1A is pink..you don't need any exposure compensation..the filters warm up the blue cast..on an overcast or hazy day..and you can leave them on to protect your lens..you can also use a 81A

Guess right!..woohooo....

and don't forget polarizers for taking glare off of glass and bluing up a sky real nice (unless it's a white sky, then fogedaboudit!)

You can however, lose one or two f-stops
when using a polarizer.
