KodakVision3 50D

Kodak Vision3 50D (5203 in 35 mm, 7203 in 16 mm) is a daylight-balanced color negative motion picture film, rated EI 50 and processed in ECN-2 [1]. Kodak calls it its finest-grain motion picture film [1]. Still photographers know it mostly as CineStill 50D, which is reportedly the same film with the rem-jet backing removed so that labs can develop it in C-41 [7] [12].

Look and color

• Natural, accurate color. Kodak describes color “full of color and detail” within the Vision3 family look [1]. Analog.cafe finds natural colors, comparable to Portra 160, with more saturation in warm light such as golden hour [6], and a little more saturation than Portra 160 in its CineStill 50D review [7]. Emulsive found the tones fresh, neither too warm nor too cold [8].
• Skin. PetaPixel calls the skin tones of CineStill 50D “some of the most accurate skin tones we have seen in a color negative film” [10].
• Scans. The same review says it often needs color correction after scanning, since it typically scans “a bit yellow and sometimes green” [10].
• Saturation: the sources disagree. PetaPixel describes a softer, more pastel look, with lower saturation and contrast than Ektar or Portra [10]. Shoot It With Film found “beautiful color and contrast” in full sun, with some resemblance to Kodak Gold 200 [9]. Both reviews concern CineStill 50D, that is, C-41 development.
• C-41 versus ECN-2 is not settled either. Analog.cafe says C-41 adds contrast and saturation compared with ECN-2 [6]; PetaPixel says cross-processing in C-41 gives slightly less saturated results [10].

Tonality

• Curve. On the characteristic curves, the straight section is long, from about −4 to +6 stops, with a soft toe and a midtone slope of about 0.55 (our reading of the graph) [1].
• Highlights. Kodak says the film has “unrivaled highlight latitude”: up to two stops more image information can be extracted from scene highlights, and it stresses high-contrast daylight exteriors [1]. Analog.cafe reads about 11 stops of dynamic range in ECN-2 [6] and found overexposure by up to one stop handled well [7].
• Contrast. PetaPixel finds contrast notably lower than competing stocks [10], which it sees as useful when saturated color might distract [10].
• Metering. Kodak’s exposure index is 50 in daylight and 12 under 3200 K tungsten with an 80A filter. Reciprocity needs no correction from 1/1000 s to 1 s [1]. At ISO 50, Shoot It With Film found moving subjects hard to shoot even in bright daylight [9].

Grain and sharpness

Kodak publishes granularity only as curves, measured with “modified measuring techniques”. The readings below compare Vision3 stocks on the same method; we do not compare them with the RMS figures of still films.

• Values are our reading of logarithmic graphs, so approximate.
• Reviews agree with Kodak. Emulsive calls the grain fine [8], and Analog.cafe describes exceptionally fine detail suited to large prints, whatever the developer [6]. PetaPixel finds it exceptionally fine for ISO 50, suited to enlargements, especially in medium format [10].
• Sharpness. Kodak publishes a modulation transfer curve but no resolving power figure [1].
• Halation. Kodak’s film has a rem-jet backing [1]. CineStill 50D, sold without it, shows red halos around bright lights, less pronounced than on CineStill’s faster stocks [7] [8] [10]. CineStill says its films made without the anti-halation layer are more sensitive to halation [11].

Spectral sensitivity

On the datasheet chart, the blue-sensitive layer has the highest peak, about 1.8 near 465 nm on the log scale, against about 1.6 for green near 550 nm and about 1.55 for red near 650 nm (our reading of the graph) [1]. The layers overlap little, and their sensitivity ends at about 495, 590 and 675 nm on the chart. The printed axis labels of this chart do not line up with its grid, so we read the levels from the grid; the shapes and wavelengths do not depend on that.

Names, status and history

• Codes. 5203 (35 mm) and 7203 (16 mm) [1].
• Status. On September 30, 2026, Kodak’s motion picture site still presented 5203/7203, with an order link [2].
• 2025: AHU instead of rem-jet. Kodak announced in 2025 that all Vision3 color negatives, 5203/7203 included, would gradually lose their rem-jet backing for an anti-halation undercoat that washes away in processing, with unchanged sensitometry [3] [4] [5]. No date for 50D is given on those pages, and the datasheet of March 2022 describes the rem-jet version [1].
• CineStill 50D. Wikipedia says it is based on Kodak Vision3 50D 5203, sold with the rem-jet removed for C-41 [12]. Analog.cafe describes it as pre-processed Kodak Vision 3 film in 35 mm cassettes [7], and it is sold in 35 mm and 120 [9] [10]. CineStill’s own FAQ does not name the source film [11]. Kodak says nothing about the arrangement.
• C-41 on the Kodak film. Analog.cafe says the film works in C-41 once the rem-jet is removed [6].
