Frequently Asked Questions

For print and archival delivery, yes. TIFF stores the decoded Nikon image losslessly, so it survives repeated editing and re-saving without accumulating artefacts, and every serious imaging application opens it. JPG is smaller and better once the photo is finished and being shared.

Generally yes. A 45.7 MP D850 frame produces a TIFF with ample resolution for large-format printing, and TIFF is the format most print workflows expect. Ask whether they need a specific colour profile embedded, since that is the usual point of friction.

8-bit per channel. KoalaPic decodes Nikon RAW to 8 bits, so the TIFF holds 16.7 million colours rather than the 14-bit depth of the NEF. That is sufficient for print delivery, but heavy tonal correction is better done from the NEF in dedicated RAW software.

Substantial. A 24.5 MP Z6 III frame produces roughly a 70 MB LZW-compressed TIFF and a 45.7 MP Z8 frame can exceed 130 MB. TIFF stores pixels losslessly, so photographic detail compresses only modestly.
