Revolog ECHO 400 ISO Color Negative Film (35mm, 36 Exposures) - Single Roll

A C-41 color negative film that turns ordinary light into jewel-toned prismatic surprises.

Revolog ECHO is an ISO 400, 35mm color negative film designed for experimentation—adding gemstone-like, prismatic textures and color shifts that can feel a little otherworldly in the best way. The effect tends to intensify in darker areas and ease off in brighter ones, so you can “steer” the look with what you choose to put in shadow versus light.

Why film photographers like Revolog ECHO 400 (35mm, 36)

• Built-in special effects without post tricks → Revolog describes ECHO as combining color shifts with prismatic, gemstone-reflection textures → you get a look that feels impossible to fake cleanly in editing.

• Shadow areas carry the “magic” → the prismatic texture is described as stronger in darker parts of the frame and subtler in highlights → great for night scenes, backlit subjects, neon, interiors, and moody contrast.

• A usable everyday speed → ISO 400 rating → handheld-friendly in mixed light, and a comfortable match for street, travel, and events where you still want flexibility.

• Standard lab processing → C-41 process color negative film → easy to develop at most labs (and straightforward to scan).

• The unpredictability is the point → marketed as a film for experimenting and pushing creative boundaries → each roll can feel like a collaboration with chance.

Quick shooting note

If you want the effect to show up clearly, give ECHO the kind of scenes it likes: strong contrast, darker midtones, and texture-rich backgrounds. If you want it subtler, keep more of the frame in brighter tones.

Tradeoffs to know

This is not a “true-to-life color” film. The look is intentionally stylized and can be unpredictable—perfect when you want surprise, not ideal when you need consistent color matching across a project.

What’s included: 1 roll of Revolog ECHO ISO 400 color negative film, 35mm, 36 exposures.

Looking Glass tip: shoot a few “control frames” early on (simple scenes, consistent light). It helps you learn how your camera + metering style translates to the ECHO look on that roll.
