Alien Film Aeronega 100 - 35mm Colour Negative Film

Kodak aerial surveillance film, liberated from high-altitude reconnaissance for your ground-level photography.

Designed to map terrain from thousands of feet. Now mostly used to photograph brick walls and dogs.

Alien Film Aeronega 100 35mm Film is an ISO 100 colour negative film respooled from Kodak Aerocolor IV, an emulsion built for aerial mapping and reconnaissance. Very fine grain, high sharpness, punchy reds and lush greens, and an unusual base that is not conventionally orange-masked. No remjet, so standard C-41. 36 exposures.

What Makes Alien Film Aeronega 100 Habit-Forming

An Emulsion With a Day Job

Aerocolor IV was made for medium and high altitude mapping and reconnaissance work, and it is still used professionally for exactly that. Alien Film Lab respool it into 35mm cassettes for applications considerably less strategic than the ones Kodak had in mind.

Very Fine Grain and High Sharpness

A film engineered to resolve ground detail from altitude has to be sharp. Grain is extremely fine and resolving power is substantial, which is why this emulsion keeps appearing in conversations about the sharpest colour negative films available.

Punchy Reds, Lush Greens

Saturation sits above Kodak Portra without reaching Ektar, on a longer contrast curve than Ektar gives you. Reds are noticeably strong and scans tend to come back leaning warm, sometimes distinctly red. Strong colour without tipping into the artificial.

The Base Is Not a Normal Negative Base

This is not a conventional orange-masked colour negative, which is a consequence of the aerial origins rather than a defect. It changes how the film inverts, and scans can look wrong if whoever is handling them treats it as ordinary C-41. The film is fine. The person doing the inverting needs to know what they are looking at.

Roll to Roll Variation

The honest limitation. This is respooled film, sometimes into recycled canisters, so expect differences between rolls and batches and the occasional colour shift. It may also be susceptible to slight light leaks. Load in subdued light and treat the variation as part of what you are buying, because it is.

Broad Exposure Latitude

The emulsion tolerates a great deal. Slight over or underexposure is absorbed without complaint, and the stock as a whole is usable well outside box speed with appropriate pulling or pushing.

Standard C-41 Processing

No remjet layer to remove, unlike respooled cine stocks. It develops normally at any lab that does colour film, including here at Chemical Dependency Lab.

36 Exposures

A full 36-exposure roll in standard 35mm format. Also available in 120 medium format.

Is Aeronega the same as SantaColor, Elektra or Maverick?

They all come from Kodak Aerocolor IV. What differs is who respools it, what speed they rate it at, how it is packaged and what it costs. We stock four of them because those differences are real even when the emulsion is not.

SantaColor 100 is hand spooled in Finland and rated 100. Flic Film Elektra 100 is Canadian, DX coded and rated 100. Maverick 125 is hand-rolled in the UK, rated 125, with no DX code. Aeronega is the one that leans into the respooled character rather than smoothing it out. Given the latitude, the rating differences matter less than the spooling does.

Why do Aeronega scans look different from ordinary colour film?

The base. Aerocolor IV does not carry the standard orange mask that colour negative inversion assumes, so software and lab scanners set up for ordinary C-41 can produce odd casts. Handled correctly it inverts cleanly and gives you the colour the emulsion is known for.

Does Aeronega need special processing?

No. There is no remjet backing, so it goes through standard C-41 alongside everything else. Development is ordinary. Scanning is where the knowledge is needed, which is worth bearing in mind when choosing where to send it.

Best For Street photography, documentary work, experimental portraits and urban landscapes, particularly anything needing fine detail and strong colour. It suits photographers who prefer film with a history and some character over factory-fresh consistency. Once you have shot it, send it our way. We develop, scan and print it too, and the unusual base is exactly the sort of thing that benefits from being inverted by someone who has seen it before.

Perfect for: Making ordinary scenes look cinematic, shooting film designed for entirely different purposes, photographers who enjoy a stock with provenance, and explaining to people that yes, this is surveillance film, and no, you are not a spy.

Aerocolor IV spent years doing serious technical work while photographers argued about Portra and Ektar. Alien Film Lab put it in a cassette without sanding off the rough edges, so what you get is an emulsion with genuine capability and genuine inconsistency in roughly equal measure. Shoot it in good light, accept the variation, and it produces something that looks like nothing else on the shelf.
