What is Color Positive Film?
To understand Ektachrome E100, one must first grasp the concept of color positive film. Also known as reversal, transparency, or slide film, color positive film produces a direct positive image on the film base after processing. Unlike color negative (C-41) film, which inverts colors and tones during development, a slide film's colors and tones are true-to-life from the moment it is taken out of the developer. This makes the finished film a beautiful and vibrant artifact in its own right, perfect for projection or viewing on a light table. Color positive films generally possess finer grain and more accurate color reproduction than their negative counterparts, but they have a more limited dynamic range, demanding precise exposure. This high degree of accuracy and unforgiving nature is part of what makes shooting slide film such a rewarding challenge for film photographers. All modern color positive films, including E100, use the standardized E-6 development process.
The Unique Characteristics of Ektachrome E100
When Kodak brought back Ektachrome, they did so by reviving the older E100G formulation, tweaking it for modern sensibilities. The resulting film, Ektachrome E100, offers a distinct aesthetic that sets it apart from other films on the market.
Neutral Color and Low Contrast
While slide films are famous for their bold saturation, Ektachrome E100 is known for its neutral color balance and natural color rendition. Compared to the vibrant, hyper-saturated hues of Fujifilm Velvia, Ektachrome's color palette is more true-to-life and less stylized. This makes it particularly excellent for accurately rendering skin tones and subtle gradations in color. It features a low contrast tone scale, which provides excellent detail across the tonal range, from highlights to shadows. This low contrast profile also contributes to a relatively wide dynamic range for a slide film, giving it a level of versatility almost comparable to a color negative film.
Exceptionally Fine Grain
Ektachrome E100 utilizes Kodak's T-GRAIN Emulsion Technology, which results in an extremely fine grain structure, even in 35mm format. The diffuse RMS granularity of 8 is one of the lowest available in a modern color film, on par with Fujichrome Provia 100F. For photographers, this means images that are incredibly sharp and clean, capable of producing remarkably detailed scans and larger enlargements without noticeable grain.
The E-6 Development Process
As a color positive film, Ektachrome E100 must be developed using the E-6 chemical process. This multi-step process is more complex than the C-41 process for color negatives, and not all photo labs offer it. However, many labs specializing in analog photography do provide E-6 development, often with options for push- or pull-processing to manipulate contrast and speed. After developing, the resulting slides can be scanned for digital use or appreciated as physical transparencies. It is also possible to cross-process Ektachrome E100 in C-41 chemicals for creative, high-saturation, high-contrast results.
E100 vs. Color Negative Film: A Side-by-Side Look
Comparing Ektachrome E100 to color negative film, such as Kodak Portra or Ektar, reveals key differences in how photographers should approach their craft and what results they can expect.
| Feature | Kodak Ektachrome E100 (Color Positive) | Kodak Portra / Ektar (Color Negative) |
|---|---|---|
| Final Image | Positive image (transparency/slide) on the film base. | Negative image (reversed colors) on the film base. |
| Development | E-6 process, fewer labs offer this service. | C-41 process, widely available. |
| Exposure Latitude | Very limited; requires precise metering to avoid blown highlights. | Much more forgiving; can handle significant over- or underexposure. |
| Color Rendition | Neutral, accurate, and faithful to the original scene. | Variable; Portra offers warm, subtle tones while Ektar is highly saturated. |
| Grain | Extremely fine grain (RMS 8). | Fine, but generally more pronounced than E100. |
| Final Output | Viewed directly on a light table or projected. Scanning produces a very workable digital file. | Requires scanning and inversion for a positive digital image, or printing onto photographic paper. |
Tips for Shooting with Ektachrome E100
To get the best results from Ektachrome E100, meticulous technique is key. Here are some tips for success:
- Meter Carefully: Due to the film's limited exposure latitude, it's crucial to meter correctly. It's often recommended to expose for the highlights, allowing shadows to fall where they may. A handheld light meter can be an invaluable tool.
- Embrace Neutrality (or Warm It Up): E100 offers beautifully neutral colors, but some photographers prefer a warmer look. This can be achieved by using warming filters like a Tiffen 812 during shooting or by making slight adjustments during the scanning and post-processing phase.
- Consider Filters: For specific situations, filters can help. When shooting under a blue sky, the shadows can have a distinct blue cast, which a warming filter can neutralize. Similarly, using a graduated neutral density (GND) filter can help manage high-contrast scenes that might challenge the film's dynamic range.
- Find a Reliable Lab: Not all labs handle E-6 processing. Before you start shooting, make sure you know where you can get your film developed. Some labs even offer mail-in services.
- Handle Scanning with Care: For digital output, Ektachrome slides are easier to scan than color negatives because they serve as a perfect color reference. A technique known as histogram stretching can help improve clarity and color rendition on initial scans.
Conclusion: The Enduring Appeal of Ektachrome E100
Ektachrome E100 is indeed a color positive film, and its characteristics make it a unique and powerful tool for discerning photographers. It may be less forgiving than its color negative cousins, but that precision is precisely what allows it to capture stunningly detailed, sharp images with authentic color. The magical experience of holding a developed slide up to the light is something digital photography can never replicate. By understanding its nuances and respecting its limitations, photographers can achieve breathtaking results that stand the test of time, just as classic Ektachrome images have for generations. For any photographer looking to explore the world of transparency film, Ektachrome E100 is a perfect starting point, offering a glimpse into the beautiful, tangible world of analog color done right.

FAQs
Question: What is the main difference between color positive and color negative film? Answer: Color positive film (like E100) creates a true-to-life positive image directly on the film, while color negative film produces a reversed, color-inverted negative that must be printed or scanned to become positive.
Question: Why is E100 considered less forgiving than color negative film? Answer: E100 has a narrower dynamic range and less exposure latitude. If you overexpose it, you lose highlight detail much more quickly than with a color negative film.
Question: Does Ektachrome E100 have vibrant or muted colors? Answer: Ektachrome E100 has moderately enhanced, vibrant colors but a neutral tone scale. It's not as aggressively saturated as films like Velvia, offering a more natural and accurate color palette.
Question: What is the E-6 process, and is it hard to find labs that do it? Answer: E-6 is the specific, standardized chemical process used to develop color positive films. Because it is less common than C-41, not all labs offer it, but many specialty labs do, often with mail-in options.
Question: Can you get good results from scanning E100 film yourself? Answer: Yes, Ektachrome E100 is highly suitable for scanning. The fine grain and neutral balance lead to very detailed and workable digital files. The developed slide acts as a built-in color reference, simplifying the process.
Question: What is the best type of photography for Ektachrome E100? Answer: E100's natural color rendition and sharpness make it excellent for landscapes, nature, and product photography. It's also well-regarded for portraits because of its pleasing skin tone reproduction.
Question: Can I get creative effects with Ektachrome E100? Answer: Yes, a popular creative technique is cross-processing Ektachrome E100 in C-41 chemicals. This produces high-contrast, hyper-saturated images with interesting color shifts.
