Camera-RAW development and image encoding: how SR2 becomes PNG

The sensor-oriented SR2 data is developed into display pixels using demosaicing, white balance, tone, orientation, and color interpretation before PNG encoding. That makes the result a rendered photograph, not another untouched camera negative. The older Sony SR2 reader uses generation-specific maker data and a matching body profile before converting its sensor array into full-color pixels. 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.

Deciding when SR2 to PNG is the right conversion

PNG wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than SR2 does.

What changes between the SR2 model and the PNG deliverable

PNG supports alpha transparency that SR2 never had, so any transparent areas in the result are newly created, not carried over from the source.
Treat SR2-specific metadata fields as optional in the PNG result until you have actually confirmed they survived.

What the SR2 source carries and the PNG output demands

What can fail when SR2 camera raw image is interpreted

Older Sony color matrices and lens information may receive less testing than current ARW files.

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.

How the PNG writer handles this route

losslessly encoded pixels with full alpha transparency is what gets written, labeled as image/png. Whether that actually opens depends on the receiving application, not on the file extension.

Acceptance evidence for the converted PNG

BEFORE

Record the SR2 evidence before conversion

Compare white balance, skin tones, crop, highlight recovery, and metadata with Sony's reference output.

AFTER

Test the PNG file in its receiving workflow

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