I have ~ 9k NEF photos of a Nikon D5000 that currently occupy ~ 100GB. It's been more than 8 years without touching them, so I don't see a reason to suppose that I will process and edit them.
I would like to convert them in batches to a bitmap format to save space, and I want them to look as close as possible to how the image would look on my camera screen at that time (since I was probably optimizing for that). I was thinking that the best option would be to convert in batches with Capture NX-D, but it seems to alter the colors compared to the standard preview of NEF on MacOS (some problems I noticed are less vivid colors, missing details, lighter shadows and changes Of temperature).
- Is it just that I have gotten used to seeing the MacOS representation of the images over the years, but the NX-D representation is more accurate than it should have been on the camera screen?
- Logically speaking, wouldn't I like to convert to 16-bit JPEG or even HEIF / HEIC to get better quality in smaller sizes? (NX-D only offers standard JPEG).
- Should I optimize to get the best images instead of the ones closest to the render on the camera? How can I do that without marking image by image that I like the result?
- Is there any reason to keep the images in NEF instead of converting them?
This question is similar, but obsolete, as well as a slightly different use case: load duplicates with unspecified quality versus obtaining the best possible bitmap to discard the original.
