I've recently acquired a Nikon D810 with firmware 1.00. I'd like to upgrade the firmware to the current 1.14, but do I need to do this incrementally or can I just proceed with the current version? I'm also looking for the most accurate Raw converter to convert NEF files to DNG, TIFF, etc. for editing in LR, or PS. I'll be using a Color Checker Passport as part of my workflow too. Thanks for any suggestions.
