Wet Gate vs. Digital Software Scratch Removal
Analyze the trade-offs between physical optical scratch removal and post-scan software interpolation.
Is physical wet gate printing still necessary in the age of advanced AI and digital restoration software? The answer lies in the distinction between capturing real data and interpolating missing pixels.
Digital Artifacts and Interpolation Risks
Software 'dust-busting' and scratch removal algorithms work by identifying defects and interpolating pixels from adjacent frames or surrounding areas. On highly detailed film grains or fast-moving action, this can create digital artifacts, soften the image, or accidentally delete real visual data (like thin wires, rain, or stars).
The Wet Gate Advantage
Wet gate scanning does not interpolate. It physically allows the scanner's sensor to capture the actual, original emulsion details *through* the physical scratch. The original grain structure and fine details remain 100% pure and untouched.
