HDRI to PGM 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 PGM files?

The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
