Limits
Starting point: NEF - NEF is Nikon's raw sensor format with unprocessed data and shooting metadata. Needs demosaicing first; exposure stays adjustable until export. Readers map it to the underlying bitmap type before conversion. Export PNM from NEF at matched dimensions; every pixel maps across, so large sources stay large.
