Limits
Starting point: CR2 - CR2 is Canon's raw sensor format holding unprocessed Bayer data plus metadata. Needs demosaicing first; white balance stays adjustable until export. Readers map it to the underlying bitmap type before conversion. Export PNM from CR2 at matched dimensions; every pixel maps across, so large sources stay large.
