Format referenceWhy convert NEF to PNG?
- Conversion is useful when the destination has a strict format requirement.
- A converted copy keeps the original file intact for comparison and future edits.
- The output can be tested in the destination workflow before the original is archived.
- A separate copy makes it easier to compare the old and new behavior.
Will quality change?
PNG is a lossless image container, but it is not a time machine: compression artifacts already present in the NEF source remain. The original source remains the best reference for comparison.
