Why convert ARW to TIFF?

Want faster load times and lower bandwidth costs? Switch from ARW to TIFF. The difference is dramatic: lossless RAW vs lossless, 14-bit per channel vs 48-bit. Converting ARW RAW images to TIFF 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. In short, this is less about one format being 'better' and more about matching the tool to the job.
