- Effects: texture, clarity, dehaze, vignette and film grain.
- Presets: built-in film-simulation, analog and cinematic looks, plus Lightroom .xmp preset import.

Private by design
Unlike most online editors, OpticRaw never uploads your images. All processing happens on your own device using GPU acceleration, which also means editing stays smooth even with 40-megapixel photos.
