ARW to BMP: the camera-raw development and image encoding route explained

The sensor-oriented ARW data is developed into display pixels using demosaicing, white balance, tone, orientation, and color interpretation before BMP encoding. That makes the result a rendered photograph, not another untouched camera negative. The Sony-oriented decoder resolves the body model and maker metadata before applying the color matrix, black level, lens treatment, and requested white balance. 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 - Sony Alpha raw sensor data with camera settings and preview imagery. Written image - A broadly understood bitmap with straightforward pixel storage and little compression.

INPUT MODEL

ARW

ARW camera raw image

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

Family: Images
MIME: image/x-sony-arw

OUTPUT MODEL

BMP

BMP raster image

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

Family: Images
MIME: image/bmp

When to actually choose ARW to BMP

BMP wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than ARW does.

What changes between the ARW model and the BMP deliverable

The source stores Sony Alpha raw sensor data with camera settings and preview imagery; the destination stores a broadly understood bitmap with straightforward pixel storage and little compression. Compare application metadata after that structural change.
Metadata handling differs between ARW and BMP; do not assume every application-specific field carries across untouched.

Reading ARW correctly and satisfying what BMP expects

ARW

What can fail when ARW camera raw image is interpreted

Creative Styles, lens profiles, and compressed-raw behavior may not translate into a neutral third-party development.

BMP

What BMP raster image cannot safely promise

BMP derivatives are often much larger than web images and may encode alpha or row order differently between apps.

ENGINE

How the BMP writer handles this route

The writer builds a broadly understood bitmap with straightforward pixel storage and little compression and labels the result as image/bmp. The receiving application - Not the extension alone - Is the final compatibility test.

Checking the BMP result before you trust it

BEFORE

Record the ARW evidence before conversion

Compare skin tones, shadow noise, highlight recovery, lens correction, and the recorded capture metadata.

AFTER

Test the BMP file in its receiving workflow

Confirm dimensions, color depth, orientation, and whether the receiving app reads transparency.
