How RAF turns into PNG: camera-raw development and image encoding

Demosaicing, white balance, tone, orientation, and color interpretation all run against the sensor-oriented RAF data before PNG encoding even starts. What comes out is a rendered photograph, never another untouched camera negative. The RAF reader accounts for the Fujifilm sensor arrangement and camera metadata before demosaicing, cropping, and mapping the capture into display color. PNG delivery preserves exact raster samples with optional full alpha and color metadata, but file size, palette reduction, animation absence, and profile handling still vary.

Decoded canvas - Fujifilm raw sensor data including camera settings and, for many cameras, a non-Bayer color filter layout. Written image - Losslessly encoded pixels with full alpha transparency.

Deciding when RAF to PNG is the right conversion

Choose PNG when its particular balance of compatibility, alpha, animation, and file size matches the destination better than RAF.

What changes between the RAF model and the PNG deliverable

PNG supports alpha transparency that RAF never had, so any transparent areas in the result are newly created, not carried over from the source.
RAF and PNG use different metadata conventions, so application-specific fields should be treated as optional until verified.

RAF source facts versus PNG output requirements

RAF

What can fail when RAF camera raw image is interpreted

X-Trans demosaicing, Film Simulations, and lens corrections differ noticeably between raw developers.

PNG

What Portable Network Graphics cannot safely promise

PNG is inefficient for many photographs, and indexed optimization can reduce a smooth palette even without JPEG-style loss.

ENGINE

How the PNG writer handles this route

The writer builds losslessly encoded pixels with full alpha transparency and labels the result as image/png. The receiving application - Not the extension alone - Is the final compatibility test.

How to confirm the converted PNG actually works

BEFORE

Record the RAF evidence before conversion

Inspect fine foliage, false color, skin tone, Film Simulation intent, highlights, crop, and lens geometry.

AFTER

Test the PNG file in its receiving workflow

Inspect transparent edges, gradients, exact dimensions, color, and small text at 100%.
