N-Log to Rec.709

N-Log is Nikon’s log profile on the Z bodies. It is well behaved and slightly under-served — there are far fewer LUTs authored for it than for Sony or Canon, which is a nuisance if you shoot Nikon.

What a correct N-Log conversion does

Nikon records N-Log against BT.2020 primaries, so the conversion inverts the N-Log curve and then maps BT.2020 to Rec.709. Any of the look packs here can carry that decode: pick N-Log as your footage type before downloading and it is baked into the .cube.

Both halves live inside the .cube you download, so the conversion cannot be forgotten, applied twice, or stacked in the wrong order — the three ways log grades usually go wrong.

The mistake to avoid

Using a generic “log to 709” LUT built for a different camera. The curves are not interchangeable, and on N-Log the mismatch usually shows up as milky, low-contrast blacks.

Using N-Log with any pack

No pack here is authored specifically against N-Log footage, but every grade in the library can carry its conversion: choose N-Log as the footage type in the LUT Library and the decode is written into whichever .cube you download. If you want a starting point, the free conversions show what a neutral decode should look like.

Common questions

Why does my N-Log footage look grey and washed out?+

Because it has not been decoded yet. N-Log stores far more dynamic range than a normal picture profile by recording a flat, low-contrast signal — that is the point of it. A conversion to Rec.709 maps it back to an image meant to be looked at.

Do I need a separate conversion LUT and then a creative LUT?+

Not here. Pick N-Log as your footage type before you download and the N-Log → Rec.709 conversion is baked into the same .cube as the look, so it is one node in Resolve or one adjustment layer in Premiere.

Which cameras record N-Log?+

Nikon Z6/7/8/9, Z6III. If your camera records N-Log, these conversions apply to it.

Which LUTs can I use with N-Log?+

All 175 grades in the library can bake a N-Log conversion in — choose N-Log as the footage type before downloading and it is written into the .cube. The free conversions at https://ireelz.com/luts/free are authored for specific cameras, so use those if you shoot one of them.
