Tweddo has revolutionized the photo preservation landscape by altering how film scans utilize infrared data for defect removal. Traditionally, infrared digital image cleaning—commonly known as Digital ICE (Image Correction and Enhancement)—had to be baked directly into the image during the physical hardware scanning process. Tweddo’s software breakthrough decouples this step, allowing archivists and photographers to extract and use the raw infrared alpha channel to apply dust and scratch cleaning post-scan, at any point in a post-processing workflow. The Core Technological Shift
Decoupled Processing: Traditional hardware-based cleaning forces a permanent, destructive scan edit. Tweddo saves the infrared raw data into an alpha channel layer.
Non-Destructive Workflows: Users can turn the infrared dust and scratch removal on, off, or adjust its sensitivity later. This prevents the accidental softening of fine, valid image details.
Batch Automation: Designed specifically as a multi-threaded batch engine, it processes large-scale digital archives concurrently across all available CPU cores. Why This Architecture Matters
When film is scanned, an infrared light source detects physical surface anomalies like dust, hairs, and scratches because infrared light passes completely through color film emulsion but bounces off physical debris.
By moving the “cleaning code” out of the scanner’s firmware and into an external batch-processing environment, Tweddo allows you to preserve a perfect “raw master” of a slide or negative while applying highly precise, non-destructive cosmetic repairs afterwards. Available Versions and Pricing
