It boasts one of the world’s highest levels of grain quality and sharpness, while delivering the same vivid colour reproduction and regulated grey balance as that of ISO 100 film. It produces fine results in push/pull processing for exposures ranging from –1/2 stop to +2 stops. These qualities, together with its high colour saturation, make Provia 400X a highly versatile film for many applications, including landscape, nature, sports, portrait and fashion photography.

Provia 400X uses Fujifilm’s newly developed Epitaxial Sigma Crystal (ESC) technology. The result is an ISO-400 film with an extremely high granularity (RMS11) approaching that of ISO-100 reversal film.

Features

• Brilliant Color Reproduction
  Brilliant ISO 100-level color reproduction through the incorporation of new-generation couplers and Multi-Color-Correcting Layer Technology.
• Fine Grain
  RMS granularity of 11, one of the world's highest levels among ISO 400 color reversal films.
• Rich Tone Reproduction
  Smooth tone reproduction from the highlights to the shadows and subtly differentiated gray gradation.
• Excellent Long-exposure Suitability
  Minimal reciprocity-related speed reduction and color balance variation in long exposures.
• Superb Push/Pull Processing Suitability
  Minimal color and gradation variation during push/pull processing from -1/2 stop (E.I.280) to +2 stop (E.I.1600), and up to +3 stops (E.I.3200), depending on the subject, making this film ideal for lowlight and other situations requiring high film sensitivity.
• Enhanced Color Image Storage Permanence and Fade-resistance
  Dramatic improvement over RHPIII in color image storage permanence and color fading resistance as a result of new-generation couplers.

Note

• RMS stands for “Root Mean Square”, a widely used standard method for measuring the degree of grain in photographic film. The lower the RMS number, the smaller the apparent grain.
