Camera-RAW development and image encoding: how PEF becomes BMP

Demosaicing, white balance, tone, orientation, and color interpretation all run against the sensor-oriented PEF data before BMP encoding even starts. What comes out is a rendered photograph, never another untouched camera negative. A PEF decode uses the Pentax model to select compression handling, sensor geometry, black level, white balance, and color calibration. BMP output writes a single flat pixel surface with an explicit row order and color depth, built for simple bitmap interchange rather than layers or multiple resolutions.

Decoded canvas - Pentax raw sensor data with camera settings, preview, and model-specific color information. Written image - A plainly structured bitmap with minimal compression that most software can read.

INPUT MODEL

PEF

PEF camera raw image

Used for storing the camera's native sensor capture before editing.

Family: Images
MIME: image/x-pentax-pef

→

OUTPUT MODEL

BMP

BMP raster image

Designed for pixel-based artwork, scans, and photographs.

Family: Images
MIME: image/bmp

When to actually choose PEF to BMP

BMP 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 BMP deliverable

The source stores Pentax raw sensor data with camera settings, preview, and model-specific color information; the destination stores a plainly structured bitmap with minimal compression that most software can read. Compare application metadata after that structural change.
Treat PEF-specific metadata fields as optional in the BMP result until you have actually confirmed they survived.

Reading PEF correctly and satisfying what BMP expects

PEF

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.

BMP

What BMP raster image cannot safely promise

A BMP derivative is typically far larger than a web-oriented image, and row order or alpha handling can differ between the apps that read it.

ENGINE

How the BMP writer handles this route

The writer builds a plainly structured bitmap with minimal compression that most software can read and labels the result as image/bmp. The receiving application - Not the extension alone - Is the final compatibility test.

Acceptance evidence for the converted BMP

BEFORE

Record the PEF evidence before conversion

Inspect white balance, greens, highlight recovery, distortion correction, crop, and EXIF.

AFTER

Test the BMP file in its receiving workflow

Check the dimensions, color depth, and orientation, and confirm whether the app you're using actually reads BMP transparency.
