Why convert NEF to JP2?

NEF served its purpose well, but modern workflows increasingly favor JP2 for High-quality professional images. The shift is worth making. Converting NEF RAW images to JP2 applies essential post-processing: white balance, demosaicing, and tone mapping. The result is a standard image ready for printing or further editing in any software. This is one of those changes that pays for itself almost immediately.
