Develop Modes

f8 Develop converts each roll using the mode set in the Film Base control. To set the default for new rolls, use Settings → Output → New Roll Develop Mode; you can change any individual roll from the Film Base control at any time.

Also in Settings → Output, When Opening a Roll controls what's selected when you open a roll — your last-viewed frame (the default) or the entire roll for batch edits.

• Adaptive (the default on new installs) — Automatically applies conversion corrections to frames — just in case you've over-exposed a shot, or a roll came back washed-out or blue. The goal is to get the best possible image from each frame.
• Neutral — Uses a fixed average color-negative base for consistent, predictable results across every film and every scan.
• Auto — Reads the film border in each scan to detect the base color. Best when your scans include the full film rebate.
• Looks (Faded, Pastel, Verdant, Sundown, Punch) — Creative color presets for a stylized finish.

Adaptive also offers a per-frame Expired option for faded or expired film — it routes the frame through the Over-exposed recovery engine.

Black-and-white negatives are detected automatically and developed as true black-and-white.

Common questions

• How do I enable HDR output?

  Enable HDR Output in the Develop section. This requires HEIC format for export and an XDR display to view the full dynamic range.

• What file formats are supported for input?

  RAW files (CR2, CR3, ARW, NEF, and others), TIFF, and JPEG.

• Does f8 Develop require an internet connection?

  Never. All processing is local.

• Where are my exported files saved?

  Your configured output folder. Click "Show in Finder" in the app to open it directly.

• Is there a Windows version?

  f8 Develop is macOS-only, built specifically for Apple silicon and the Apple ecosystem.
