Camera raw conversion requires decoding, demosaicing, white balance, tone mapping, and encoder choices.
Converting DNG to PPM decodes the source image and writes a PPM output. Use this route when PPM is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on PPM compression: uncompressed.
Choose conversion targets based on PPM compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: Exif, XMP, IPTC, DNG tags.
Supported by ImageMagick, Netpbm, and technical imaging tools.
