Kodak Aerocolor IV

Kodak Aerocolor IV 2460 is a fine grain, medium contrast color negative film originally developed for aerial photography and surveillance purposes. It is known for its high resolution, wide exposure latitude and neutral color reproduction.

Features

Fine grain: Aerocolor IV has a remarkably fine grain, especially when developed at reduced contrast. This enables detailed images with high sharpness.

High dynamic range: The film can capture up to 10.5 stops, making it ideal for high contrast scenes. Details are preserved in both the shadows and highlights.

Neutral color reproduction: Aerocolor IV is characterized by accurate color reproduction. Colors appear natural and balanced, with a slight tendency toward cooler tones in the highlights and warmer tones in the shadows.

Scratch-resistant emulsion: The film’s emulsion is resistant to scratches, which is important for the longevity of the negatives.

No color mask: Aerocolor IV has no orange masking layer, which makes digitizing easier and can lead to improved color accuracy.

Uses

Although Aerocolor IV was originally developed for technical applications, it has gained popularity among creative photographers in recent years. Its unique properties make it an interesting choice for landscape, portrait and street photography.

Development

The Aerocolor IV is typically developed using the C-41 process, the standard process for developing color negative film.

However, Kodak also recommends specific development times and temperatures to achieve the film’s full potential. For example, developing at 38°C for 3 minutes and 15 seconds can result in even finer grain and an expanded dynamic range.

For best results, the film should be exposed to an exposure index (EI) of 80 when developing this film.

Digitization

Unique to Aerocolor IV is the lack of an orange masking layer. This layer is common on most color negative films and is used to compensate for chemical impurities. Since Aerocolor IV does not have such a mask, color interpretation is simplified during digitization.

Digitizing Aerocolor IV can be done in a number of ways. One way is to scan the film as a positive and then digitally invert it. This also removes the so-called “base fog,” a slight color haze that can be caused by the film base.

Another method is to scan the film directly as a negative and adjust the colors using image editing software.

However, due to its thin film base and lack of markings, scanning Aerocolor IV can present some challenges. For example, it can be difficult to see the emulsion side of the film. Additionally, the film tends to dry very flat, which can make scanning difficult.

Availability

The Kodak Aerocolor IV is still manufactured but only sold in bulk. However, individual rolls are available through various resellers who rewind and repackage the film in small quantities. These include brands such as SantaColor 100, Luminar 100, Film Electra 100 and Film Washi X.
