Choosing Your Film Stock — A Practical Guide to Nitralux's Current 3 Stocks

Three stocks. Different grain, different color science, different use cases. Here’s how to decide with the current Nitralux lineup.

Kodak Vision3 250D — The everyday stock (Free)

ISO 250 | Daylight | Fine grain

This is where most people should start. The Vision3 250D was Kodak’s workhorse daylight stock for motion picture production — used on countless mid-budget features and commercials.

Character: Natural skin tones, vibrant but not oversaturated colors, fine grain that stays out of the way. Shadows hold detail well without becoming muddy.

Best for: Daytime exteriors, travel footage, anything where you want film look without calling attention to it.

Avoid: Indoor tungsten lighting without correction — you’ll get an orange cast.

Kodak Vision3 500T — The night stock

ISO 500 | Tungsten | Medium grain

The 500T is balanced for tungsten (3200K) light. Shot under daylight, it goes cool — the distinctive blue-shifted look you see in music videos and fashion films shooting outdoors with this stock intentionally uncorrected.

Character: Rich, cooler tones in daylight. Warm and natural under practical lights. Higher ISO means more visible grain, particularly in shadows.

Best for: Night exteriors under streetlights and practical light, indoor scenes under incandescent lighting, intentional “cool” aesthetic in daylight.

Technical note: The tungsten balance is baked in. Nitralux simulates this as a color response characteristic, not just a white balance shift — so the grain structure and shadow behavior both reflect the 500T’s high-speed emulsion.

Fuji Eterna 250D — The understated classic

ISO 250 | Daylight | Fine-medium grain

Fuji’s Eterna line was their professional cinema offering before they exited the motion picture film business. Nitralux’s Eterna 250D interpretation leans toward a softer, more editorial palette than Kodak Vision3.

Character: Lower contrast, gentle saturation, calmer greens and skin tones. The image feels more restrained and polished than the Kodak stocks.

Best for: Editorial footage, travel, architecture, and projects where you want a more muted base before grading.
