ReflxLab Slide 100D

Reflx Lab Slide 100D is fresh Kodak Ektachrome 100D 5294 stock, respooled into 36-exposure 35mm canisters and sold for E-6 processing. Kodak makes 5294 as Ektachrome 100D for cinematographers. The still photography world calls it slide film. Same emulsion either way. The respool just gets it into a still camera at a price below Kodak-branded Ektachrome E100.

The distinguishing detail is that 5294 ships without a remjet anti-halation backing. Vision3 color negative stocks like 50D and 500T need remjet removed before C-41 processing, which is the whole reason CineStill exists. Ektachrome 5294 is a reversal motion picture stock and has no remjet to remove. Any properly equipped E-6 lab can run it without special preparation. That alone makes it more accessible than the popular CineStill cine respools.

Color rendering is neutral and clean, with the slightly cool, slightly green-blue cast current Ektachrome carries. Skin tones are honest rather than warm. Greens are accurate. Blues hold well in skies. Compared with Fujifilm Provia 100F the saturation is similar but the grain is slightly tighter. Compared with Velvia 50 it is a different category entirely; Slide 100D is not engineered to push colors past the real world.

Process in E-6. Rate at box speed. The film tolerates a half stop of overexposure better than underexposure, which is standard reversal behavior. Bracketing matters because there is no negative latitude to save you in post.

Format is 35mm only from Reflx Lab. For 120 you would need Ektachrome E100 proper.

Reciprocity exponent is 1.0. Zone Light Meter still passes the calculation through past one second, but at this exponent the metered time is the shot time. A 4-second reading stays at 4 seconds. For long-exposure cityscape or astro work that is the property you want, though Ektachrome past about ten seconds drifts toward magenta in shadows regardless of what the math says.
