Hi everyone,
We would like to share a project from OpenImageLab designed to simplify the scanning and processing workflow for slide scanner owners using Darktable 5.x.
The Problem
Getting consistent results in Darktable from positive film scanners can be tricky for beginners, especially when dealing with proprietary software outputs and trying to maintain a non-destructive workflow in Darktable 5.x.
The Solution
We have created a very comprehensive step-by-step tutorial and a dedicated .dtstyle aimed at a “Scene-Referred / Sigmoid” workflow. The guide covers:
- Scanning: How to set up 48-bit HDR (Linear Gamma) raw scans to preserve maximum data.
- Processing: A specific Darktable style (
Plustek8300i.dtstyle) to handle the inversion, initial color correction, dehazing and sharpening automatically. - A dedicated chapter treats the red eye removal.
- Theory: Detailed explanations of why specific modules are used, which presets are required, helping users understand the “how” and not just the “what.”
