Camera-RAW development and image encoding: how PEF becomes TIFF
The sensor-oriented PEF data is developed into display pixels using demosaicing, white balance, tone, orientation, and color interpretation before TIFF encoding. That makes the result a rendered photograph, not another untouched camera negative. A PEF decode uses the Pentax model to select compression handling, sensor geometry, black level, white balance, and color calibration. TIFF output can describe high-bit-depth pixels, alpha, varied compression, and multiple image directories, but the chosen writer profile determines which of those features is present.
Decoded canvas - Pentax raw sensor data with camera settings, preview, and model-specific color information. Written image - A flexible raster container that can hold high bit depth, multiple pages, alpha, and varied compression.

When to actually choose PEF to TIFF
TIFF wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than PEF does.
What changes between the PEF model and the TIFF deliverable
- TIFF supports alpha transparency that PEF never had, so any transparent areas in the result are newly created, not carried over from the source.
- TIFF can hold multiple pages, but a single PEF source only fills one; the rest of that structure stays empty rather than being generated.
- PEF and TIFF use different metadata conventions, so application-specific fields should be treated as optional until verified.
What the PEF source carries and the TIFF output demands
What can fail when PEF camera raw image is interpreted
Custom Image settings, lens corrections, and compressed-raw details may not match Pentax's rendering.
What TIFF raster image cannot safely promise
Apps support different TIFF subsets, so multipage files, CMYK, layers, or unusual compression may fail to open.
How the TIFF writer handles this route
The writer builds a flexible raster container that can hold high bit depth, multiple pages, alpha, and varied compression and labels the result as image/tiff. The receiving application - Not the extension alone - Is the final compatibility test.
Acceptance evidence for the converted TIFF
Record the PEF evidence before conversion
Inspect white balance, greens, highlight recovery, distortion correction, crop, and EXIF.
Test the TIFF file in its receiving workflow
Check every page, bit depth, color mode, resolution tag, compression, and alpha channel.
