Apple Log vs Apple Log 2 on the iPhone 17 Pro

The difference is the color gamut, not the dynamic range. The camera screen calls both of them ProRes Log, and DaVinci Resolve 21 only has one of them.

Shooting Apple Log and want it finished? PursuitLuts for Apple Log has the conversion and the look inside one file.

The short version

Apple Log came with the iPhone 15 Pro. It records Rec.2020 primaries.

Apple Log 2 came with the iPhone 17 Pro. It records a wider gamut of Apple's own, reaching further into saturated blues, reds and magentas. That is useful for neon and colored stage light, where Rec.2020 runs out first.

What Apple Log 2 is not is more dynamic range. The gamma curve is reported to be the same one, so exposure and contrast behave exactly as they did. If you have read that Log 2 buys you stops, that is wrong.

They are still not interchangeable. Because the gamut differs, footage shot in one and read as the other comes out with hue and saturation skewed, and the error happens before any LUT, so nothing downstream repairs it.

How confident we are in that

The gamut difference is agreed on by every source we found. The claim that the gamma curve is identical is the common one but not a universal one, and Apple has not published a spec sheet we can point you at. We have measured Apple Log ourselves. We have not measured Apple Log 2, because Resolve cannot read it and we will not publish numbers we did not take.

So: treat the gamut difference as solid, treat "same curve, no extra range" as very likely, and do not trust anyone who gives you precise Log 2 numbers without saying where they came from.

Resolve 21 has one of them

We checked this directly rather than reading about it. Setting the input gamma through Resolve's own scripting interface, Resolve 21.1.1 accepts "Apple Log" and rejects "Apple Log 2". It is not a hidden entry or a different spelling. It is not there.

So if you are finishing in Resolve today, shoot Apple Log. Apple Log 2 footage has no correct path through that version, with our files or anyone else's.

The camera will not tell you which you shot

This is the part that catches people. The badge on the recording screen reads ProRes Log whether you are shooting Apple Log or Apple Log 2. It looks identical.

The setting that actually says is:

Settings > Camera > Formats > ProRes Log Video Encoding

It will read Log or Log 2. On an iPhone 17 Pro that choice exists. On a 15 Pro or 16 Pro it does not appear at all, because those phones only record Apple Log and there is nothing to choose between.

If you cannot find it, that is informative by itself: your phone is recording Apple Log.

The settings for Apple Log in Resolve

Add a Color Space Transform as the first node, then set:

There is no gamut entry called Apple, and people go looking for one. There does not need to be: Apple Log records the Rec.2020 primaries, so Rec.2020 is the right answer rather than a workaround.

How we know the Apple Log conversion is right

We rendered a 64 step grey ramp and 64 color patches of known values through Resolve's own color management, then compared every one against our math.

We did it that way because the obvious method is a trap. Resolve can export a node graph as a LUT, but that export carries only the grade, not the color management transform, so it comes back as a do-nothing file that matches anything you compare it against. We caught that by testing the method on a camera we already had a reference for. More on how we check.

What we have not measured

Apple Log 2. We have not shot it and we have not measured it. Its exact primaries are not in any Apple document we can find, and published descriptions of its curve disagree with each other.

So we are not shipping a file for it, and we would be careful with anyone who is. When Resolve supports it and we can measure a phone recording it, we will say so with numbers.

If you already shot Apple Log 2

There is no honest fix in Resolve 21.1.1. You can grade it by eye and get something that looks decent, but it will not be a correct conversion and nothing will make it one. For work that matters, reshoot in Apple Log.

It is worth changing the setting before you need it rather than after.
