B/W film and IR Filter, ok?

[usccharles]

hi,

m8 is in the shop for alittle tuning, so i'm taking out my hexar rf tomorrow with some b/w film. do i need to remove the IR filter or is that okay with B/W film?

thank you~

Im not sure if I'm understanding your question. I don't own either camera, but my understanding is that the M8 needed the IR filter because of a flaw in the camera design. CCDs are very sensitive to IR lightwaves and most have a built-in IR blocking filter but the one on the M8 was too weak... or "something like that", so you need to use a filter on the lens to compensate for this.

The Konica Hexar is a film camera, doesn't (obviously) use a CCD so you wouldn't need the filter you used on the M8 at all. If you're shooting a sky scene with clouds, most people would use a Yellow "Y2" filter to improve the contrast or the clouds would blend into the sky as black and white is very sensitive to blue. The yellow darkens the blue sky and an orange filter would darken it more and a red filter would darken it even more. Most use a Y2 filter. The filter factor is "2" so it cuts the light sensitivity by a stop.

Not sure if I'm understanding your quesiton but the short answer is "no", don't put the leica filter on the Hexar. You might want to use a Y2 if "puffy clouds" are in the scene.

sorry, let me clarify. i usually use a UV filter on all my lenses as protection against scratches on the lens glass, but with some of my lenses, i don't have UV filters. I only have IR filters.

I've read that using IR filters on color film will affect the image, but i don' t know if IR filters affect b/w film negatively.

i'm using b/w film tomorrow, so if IR filters are ok, i would like to leave it on.

Lately I only use ND filters in daylight, esp. sunlight. Enables me to use wider apertures. Evenings I do without filters because of ghosting risks.
I hardly use UV filters anymore.

It depends slightly on the b+w film, but they are not sensitive as far as the ir part of the spectrum. The manufacturers website will have precise details of where the film stops being sensitive, then you can compare that with the wavelengths cut by the Leica filter. There is unlikely to be any significant overlap. If there is a filter-factor on the ir-filters take that in to account when metering (though I recall that it was around 0,1 stops or so).

So, the ir-filters can probably stay on for protection purposes, with almost no effects on the light which is making the image on your film.

I think I understand the original question - for those of that shoot the M8 and a film body is there any reason to remove the IR Cut filter if shooting (in this case B&W) film?

I understand your question. As long as you are not using infrared film, I think you should be OK.
