White skin, studio, infrared

[arigram]

I have this model who is quite ginger, with long blond hair and very fair freckled skin (she's Greek too) and on my first photoshoot I realized that she glows!
Black background, softboxed strobes, PanF+ 120 at 50iso, developed normally with Ilfosol S.
Her skin glowed like a fairy and I want to take advantage of that.

I thought of using Softar filters and Red #25 on my Hasselblad, strobes and Infrared film. Unfortunately I don't have an infrared filter.
I have an old Macophot IR820c and a few Rollei Infrared.

What are your suggestions?
Will strobes work with infrared?
How should I rate and expose the film?
How should I develop it? (I have D-76, Ilfosol-S, Rodinal, Perceptol, Microphen)

Flash units have Xenon gas and are designed to output at 5500 wavelength.
I suspect the infrared wavelengths are much less present. Apparently Krypton puts out more IR. Still you never know till you try. Maybe test shots with the # 25 filter and IR film to determine the output of the flash at that wavelenght?
Good Question!

IF you want to do infrared in the studio, your best bet will be 3200K hot lights. Strobes do have infrared, but not so much.

I used to shoot Kodak HIR in the studio with a 29 filter and strobes. I found I could rate the film at 200 and got excellent results. Exactly the effect you're looking for. Maco / Rollei I have no idea so try a roll and see. I think you'll find there's more IR than you expect.

Though I've never used studio strobe with IR, at one time I used a Vivitar 283 portable flash with Kodak's HIE IR film. I used an opaque IR gel filter (#89 IIRC) on the flash (and a #25 or #29 over the lens) and it worked fine. The flash even worked on automatic well with this arrangement. I think the auto sensor was IR sensitive.

I'd be interested in seeing results with the 820 film as I'm thinking of trying it in LF.

Just bear in mind that with a proper IR filter, the Maco IR has a speed somewhere around ISO 6-12. The new Rollei may be faster, around 25-50 ISO, after filtration.

So, I guess I will add a roll or two along "normal" film during the shoot and use it an an experiment.

Not terribly germane here, but I used to shoot strobes with an orange filter and HIE in the studio. (looking for an image here) But I found the results to be very good. I shot at 250ASA.

I had used candle light as well with a much more pronounced IR look (of course) and I liked that as well.

With the low ASA of the Maco film, I have been afraid to shoot it in the studio.

Best of luck, Ari.

Thanks Robert, developing won't be easy.

I also thought of something else:
I will be using white fabrics and have the idea of adding a black light to the scene.
Do you think that will work?

 

[TheFlyingCamera]

If you want to see an IR effect, white fabric as a backdrop will prevent you from seeing much of an IR effect. Also, blacklights are UV rich, IR poor.

White fabrics won't be used as a backdrop, which will be black, but as pieces of the set, including clothing.
As for the blacklight, I thought of it in regards to enhancing the glow during the normal film exposures but I am afraid that strobes will overpower it.
There isn't something like this to "enhance" the IR effect, is there?

 

[Robert Hall]

Ari,

Think more of synthetics of nylon, polyester, etc. I think this would give you a better shot at an IR effect.

Also keep in mind that Efke IR820 does not do well with #25 red filters. You'll need a darker filter like the Hoya R72 to really bring out the IR effect.

Hmmm... maybe I should refrain from using infra red then until I have a proper filter.

If you're just aiming at moving around the way her skin looks, a red filter over the lens and normal pan film will be just fine with most strobes.
Examples of what I've done with just that...

Now, the infared 'effect' is a different story, but for just that nice glowy skin, red+pan will do great.
