There's a quiet shift happening in wedding filmmaking. The iPhone in your pocket became a legitimate B-camera a couple of years ago, and most of the industry hasn't noticed yet. I've been cutting iPhone footage into real wedding films alongside my Sony bodies, and when it's shot in Apple Log and graded properly, clients cannot tell. Not "can barely tell." Cannot tell.
The catch is that almost nobody explains the full workflow, from recording settings to the finished grade. So here it is, the way I actually run it.
What Apple Log is and why you should care
Apple Log is the flat recording profile available on the iPhone 15 Pro and every Pro model since. Like S-Log3 on a Sony, it captures a wide dynamic range in a deliberately grey, washed-out image, protecting the highlights in a stained glass window and the shadow detail in a dim reception at the same time. Straight out of camera it looks broken. That's the point. All the colour decisions are deferred to the grade, where you control them.
Filming a wedding in the standard iPhone profile means the phone makes those decisions for you: crunchy contrast, oversaturated skin, highlights clipped forever. Fine for family barbecues. Not for something a couple keeps for life.
Recording settings that actually matter
Apple Log requires ProRes recording, which brings one practical reality: storage appetite. Reckon on roughly six gigabytes a minute at 4K, which means recording to an external SSD on the phone's USB-C port for anything beyond short clips. My setup for wedding work: 4K at 25 frames per second for standard coverage, 50 for anything I might slow down, exposure and white balance locked before the moment starts, never during.
The stock Camera app does the job, but the Blackmagic Camera app gives you proper manual control, false colour, and focus peaking for free, and it's what I'd recommend the moment you're taking iPhone coverage seriously.
One discipline that matters more on iPhone than on a cinema camera: expose generously. The sensor is tiny, and underexposed log footage from a small sensor turns to noise soup the moment you lift it. Protect the highlights, but keep skin bright. When in doubt on a dance floor, add light rather than ISO.
The grade: from grey to finished film
Flat Apple Log footage needs two things: a conversion to a normal viewing standard (Rec.709), and a creative grade, the actual look. You can stack those as separate steps, an official conversion LUT followed by your own correction, and there's nothing wrong with that. But for wedding volume, where you're grading hundreds of clips against a deadline, the professional shortcut is a LUT that does both in a single pass: Apple Log in, finished cinematic image out, then a small per-clip trim of exposure and white balance.
The workflow by editor: in Final Cut Pro, apply the LUT through the Custom LUT effect and it sits cleanly in the pipeline. In Premiere Pro, drop it on an adjustment layer or into the Creative tab's Look slot. In DaVinci Resolve, a node with the LUT applied does it, with your trims on a node before it. In LumaFusion, on the iPad or the phone itself, import the .cube file and apply it per clip, which means you can legitimately grade a same-day edit from the passenger seat.
The hybrid problem nobody talks about
Here's the part that decides whether iPhone footage survives the final cut: it has to match your main camera. A wedding film that jumps between a beautifully graded Sony image and a differently-coloured iPhone shot reads as amateur instantly, even to a client who couldn't say why.
The fix is grading both cameras with the same colour family. Same tone curve philosophy, same skin handling, same palette. When the S-Log3 grade and the Apple Log grade are cut from the same look, the iPhone stops being the B-camera you apologise for and becomes coverage nobody questions.
Where the LUTs fit, honestly
This is exactly why the Lussurro Cinema LUTs ship graded for both Sony S-Log3 and Apple Log: the same grade, built for both formats, so your A-camera and the phone in your pocket produce one film, not two. Each LUT takes the flat log image to a finished Rec.709 grade in one pass. You bring the per-clip trim, the same final five percent as always.
Five hand-graded LUTs for Sony S-Log3 and Apple Log, cut from one grade so every camera in your bag makes the same film. For Premiere, Final Cut, Resolve and LumaFusion.
