--- Grain Surgery 2 Adobe Photoshop 7.0 Plug-in |verified|

Photoshop 7.0 supported 16-bit editing, but many plug-ins didn’t. Grain Surgery 2 did, allowing grain removal from high-bit-depth scans (e.g., from a Heidelberg drum scanner) without posterization.

The core philosophy was revolutionary: Instead of blindly smoothing pixels, Grain Surgery 2 profiled the grain of a specific film stock or digital sensor. It created a mathematical "fingerprint" of the noise and then subtracted that precise pattern from the image. --- Grain Surgery 2 Adobe Photoshop 7.0 Plug-in
