Overview

There's a quality to the orange-filtered light that no slider in post quite captures — that thick, amber warmth that makes an autumn landscape feel like it was lit from within. The Cokin P30 85B was engineered as a practical color conversion tool for film photographers shooting tungsten Type B stock in natural daylight, but in practice it becomes a creative instrument for anyone who wants that look baked into the frame at the moment of capture. Whether you're shooting medium format film on a landscape trip or running a hybrid workflow where the aesthetic of the analog era matters, the P30 slots neatly into the Cokin P-Series system and gets to work immediately.

Built to Cokin's standard P-Series dimensions, the P30 fits any compatible holder without fuss and can be combined with other filters in the same system. The resin construction keeps weight minimal, which matters when you're already carrying a loaded film kit across terrain. It's worth keeping a microfiber cloth nearby — resin surfaces show handling marks more readily than glass — but with basic care the filter performs consistently session after session. For film shooters working in a three-grade orange system, the P30 occupies the middle position: stronger correction than the 85A, softer than the 85C's mixed-light formula. That specificity is the point — it's a precise tool for a precise need.

Key Features

Pros & Cons

👍 Pros

  • Delivers reliable tungsten-to-daylight color correction when shooting Type B film stock outdoors, saving post-processing time in a film workflow.
  • The warm amber cast adds a painterly, autumn-light quality to landscapes even on digital, giving you an in-camera look that's hard to replicate exactly in Lightroom.
  • P-Series format means it drops straight into any existing Cokin P-Series holder, no additional adapters needed.
  • Useful for portrait work where you want skin tones to read slightly warmer and more intimate straight off the roll.
  • Part of a graded system — easy to step up or down to the 85A or 85C depending on your specific film and lighting combination.

👎 Cons

  • Primarily a film correction tool — digital shooters get only a creative warming effect, which white balance adjustment can approximate for free.
  • The amber shift is fixed in strength; you can't dial in a subtler warming effect without layering a lighter filter from another manufacturer.
  • Like all resin P-Series filters, the surface is more prone to fine scratches over time than glass alternatives, requiring careful storage.
  • Requires exposure compensation of roughly one stop, which adds a variable to manage on fast-moving shoots.

Frequently Asked Questions

The P30 is calibrated for tungsten Type B film used in daylight conditions. It shifts the cooler color temperature of tungsten-balanced emulsions into natural daylight range, preventing the pronounced blue cast you'd otherwise get shooting Type B film outdoors.
Each grade targets a different scenario. The A029/85A corrects Type A tungsten film in daylight; the P30/85B handles Type B tungsten film in the same situation; the A031/85C is the choice when you're mixing tungsten and window light with daylight-balanced film. Pick based on your film stock and lighting environment.
Yes — though its primary design is color conversion for film, the P30 works in the P-Series holder on any camera. On digital, it delivers a deliberate amber cast that mimics the look of warm late-afternoon light, useful for portraits or landscapes where you want that quality baked into the file rather than added in post.
Yes, orange conversion filters reduce the light reaching the film or sensor. Expect roughly two-thirds to one stop of exposure compensation — meter through the filter if your camera allows it, or apply compensation manually when shooting in manual mode.
The P30 is built to Cokin's P-Series dimensions and slots directly into any P-Series filter holder. It can also be stacked with other P-Series filters — useful if you want to combine it with a polarizer or ND for more complex lighting control.
