Capturing The Unseen

FPP Infrachrome (Aerochome) III 35mm

Yellowstone & Grand Teton National Parks.

Yellowstone River

~

Camera: Pentax KX, 35mm

Lens: Takumar 17mm Fisheye, with Orange 056 filter. (Unless noted)

Film: FPP Infrachrome 400 (Kodak Aerochrome III), 24-exp.

Developer: E6 slide. (Can also be done in C41.)

Remarks: Metered at ASA100 (over-exposed 2-stops), developed for ASA400. Best results in strong light. Lens must be filtered, unfiltered exposures yield strong purple-cast and no IR response in the emulsion. Orange-filtered exposures yield a stronger IR-response than yellow-filtered exposures, however both produce the proper IR response. Other types of filtering also tested, listed in the captions.

The following four images are identical compositions and exposure metering, using four different filtering methods, none of which deliver an IR response in the emulstion.

Conclusion: Barring a couple metering errors on my part, and the filter-experiment frames, the film responded as it was intended. Sources of infrared light (vegetation) were rendered a strong pink, while visible-color light was shifted into vibrant tones of blue or white.

10/10 would shoot again, while supplies last.
