HDRI to ICO Conversion: FAQ

What are HDRI files?

SilverFast’s 64-bit HDRi RAW file is a TIFF that preserves a full 16-bit-per-channel RGB scan plus a separate 16-bit infra-red channel, giving 64 bits per pixel. The visible data stays completely unprocessed—no sharpening, gamma, or colour tweaks—while the IR map lets SilverFast’s iSRD (or compatible tools) later remove dust and scratches non-destructively, making it an ideal “digital negative” for archival film workflows.

What are ICO files?

ICO files contain the images used as icons for files, folders or programs on the Microsoft Windows platform.
