Favorite Camera for IR Film ?

A standard light meter has no way of telling the IR light on the subject.

Works for me.... That's all that matters....

That is true, but ...

With experience, one realizes that there is a correlation between the amount of visible light on the subject and the amount of near IR on the subject.

During the middle of the day, I had good success using an R72 filter with Rollei ISO 400 film and metering using an incident meter set to an EI of between 3 and 12.

Bracketing is your friend, and don't meter through the filter.

I would suggest there is no correlation between visible light and IR in the atmosphere.

Noted, but do you have a camera that you prefer to use?

With IR film, no.

With IR film, no.

K, thanks

I don't think that's right. After all, the sun's output is more or less consistent at some relation of visible to IR---the difference in that proportion between different times of day is just down to differences in scattering and absorption. As we all know from absorbing AA's _The Negative_ with our mothers' milk, longer wavelengths scatter less, which is why (1) red filters cut haze and (2) sunsets look reddish.

So at a clear, cloudless midday, the amount of IR is low relative to the visible, because not so much visible light is getting scattered; in hazy golden-hour light, the proportion is high. At a given location, I think it's possible to work out metering and compensation practices for these cases and interpolate between them.

By the way, I've also had some luck metering through an 89B (mainly in sunny conditions and temperate latitudes). The meters in question may just be reading off the little bit of far-visible-red that gets through the filter, or they may be sensitive a bit beyond the visible spectrum---I don't know why it's worked but it has.

My favorite camera for IR is FM3n with cheap Soviet made Universal Turret Viewfinder.
The viewfinder has 35mm frame so Nikkor 35/2 follows when they go out.

I have also metered IR through the filter. Z

Favorite Camera for IR Film ?

The 4x5 view, 6x9cm rangefinder, 6x7cm rangefinder, 6x6cm TLR, and 35mm rangefinder were my favorite cameras for shooting infrared film.

The 35mm SLR was never a favorite for infrared film because it was too difficult to focus and compose with the filter in place and it was too slow to operate if I had to remove the filter too often to focus and compose.

I used a Hoya R72 infrared filter.

I mounted the camera on a tripod.

I used a handheld light meter to estimate the exposure.

I bracketed the exposure.

I bracketed the focus.
