Filters for indoor K40 use

[HenrySuper8]

Do I need some kind of filter to use K40 with Artificial Light??

Where do I get filters for my Canon 514 XL-S ?

The good news is NO...who hooooo!

Kodachrome is indoor balanced, so you remove the filter (Assuming your camera has a filter switch).

You only use the 85 filter when outdoor light is your main source of light.

Kodachrome 40 is ASA rated 40 when shooting with no filter. When shooting with the filter, the ASA rating is 25.

Indoor lights equal an ASA rating of 40. Outdoor light (with 85 filter in position) ASA rating of 25.

Well, the swich is with symbols.. you can choose between a light bulb (artificial) and a sun (natural)...
If i have K40 in my camera i should put the switch to the light bulb symbol when filming indoor, right??

Mikey B and Henry Super-8, you're both right on the money! [img]graemlins/thumbs_up.gif[/img]

Maybe that's why Kodak did away with K25...they figured it's 25 asa outside anyway...just my thoughts on corporate reasoning! Mikeyb

If I could ad to the subject; I've done a test roll of K-40 shot with Halogen lights (750 watts). It came back extremely yellow. I do a lot of computer editing, but I'm not sure I can compensate for the lack of other colors. Any suggestions? Filter?

Thanks

Yeah but I thing Mikey B's point about corporate reasoning is right on. Your right, it still is ASA 40, but the idea is you've actually gained 2/3 of a stop of sensitivity for indoor shooting, which I think is a big deal.

Frankly, ASA 25 for outdoors, even it is actually a 40 ASA film, is slow either way. As for the filter being in the optical path, and therefore is one more thing that might actually cause a problem, I don't know enough (or ANYTHING) about that.

Perhaps the next question would be, WHERE is the best place to put any filter on any camera to minimize any negative impact to the image before it reaches the film?

I believe my film project that I shot last November was enhanced because I used an external 85B filter. I shot Ektachrome outdoors at night (via time-exposure) and my camera was missing the 85 filter.

I bought an external 85B filter that looked flawless, the eveness of the color on the filter was just breathtaking.
