About the PEF format
RAW — Pentax PEF RAW
PEF is Pentax's proprietary RAW format used in Pentax DSLR and medium-format cameras. It captures full sensor data for flexible post-processing and is the native format for Pentax's unique weather-sealed camera bodies.
Common uses
- Pentax DSLR and medium-format photography
- Outdoor and weather-sealed camera workflows
- Landscape and nature photography
- Professional studio post-production
About the RGBO format
RGBO — Raw RGB with Opacity
RGBO is a variant of the raw RGBA format used by ImageMagick where the fourth channel represents opacity rather than alpha, with inverted semantics (0 = fully transparent, like an alpha channel). It is used internally in ImageMagick for specific color operations.
Common uses
- ImageMagick internal color processing
- Opacity-based compositing workflows
- Intermediate format in image processing pipelines
- Custom color channel manipulation
