About the PWP format
PWP — Seattle Film Works Multi-Image
PWP is a multi-image variant of the Seattle Film Works format, capable of storing multiple photographs in a single file (similar to a simple photo album). Like SFW, it originates from the Seattle Film Works film digitization service of the 1990s.
Common uses
- Recovering Seattle Film Works multi-photo files
- Converting 1990s SFW photo collections
- Legacy film digitization service archive recovery
- Historical family photo preservation
About the HDR format
HDR — Radiance RGBE High Dynamic Range
HDR (Radiance .hdr) is a high dynamic range image format developed for the Radiance rendering system. It stores luminance information far beyond standard 8-bit images using a shared-exponent encoding, making it the standard for HDR environment maps in 3D rendering.
Common uses
- 3D rendering environment maps (IBL)
- HDR panorama photography storage
- VFX and CGI lighting reference images
- Tone mapping source images
