The Allure of Built-In LUTs
Walk onto any mid-tier commercial set in LA and you’ll spot at least one DP swiping through the Alexa’s LUT menu like it’s a gelato sampler. It’s tempting. These pre-made looks baked right into the camera settings promise instant style. Skip the colorist, right? Except… no.
Even on fast-turnaround branded shoots, I’ve seen DITs slap the factory Rec709 LUT on every shot because, "The client wants to see color now." And the image does look punchier on that monitor. But you know what's also happening? You’re committing to a baked-in look before you’ve even got the lights set. That’s not filmmaking—that’s coloring by numbers.
Not saying built-in LUTs are useless. There’s a place for them on run-and-gun doc gigs where you genuinely can’t throw time at every shot in post. But relying on them for anything you’re proud to put your name on? That’s a pass from me.
Where Built-In LUTs Fall Short
I’ve lost count of the number of times clients fell in love with the on-set monitor look, only to later hate it in edit. Why? Because the default camera LUT rarely matches what you actually saw on set. Colors shift. Skin tones can get nuclear, or worse, waxy. And when you start grading in post, you’ll find you’re fighting that look instead of shaping your image.
Had a DP last year on a food shoot swear by the Sony Venice’s S-Cinetone LUT. It looked great on cheese and tomatoes under that mixed tungsten window light—until we got into Resolve, tried to match B-cam (which somehow landed on a different LUT mid-day), and suddenly had marinara looking like nuclear fallout. There’s no elegant recovery. You end up either living with a patchwork color grade or rolling back to the LOG and starting from scratch, wasting hours.
Good LUTs are starting points, not magic wands. The built-ins were designed by committee for "average" scenes. When was the last time you shot an "average" project? I sure haven’t.
The Better Alternatives
Here’s what actually works: Build your own base LUT or grading template for each production. Spend an hour before your shoot testing in the environment you’ll actually be filming—real locations, real lighting. I know, that sounds painful. But it saves you so much time when you hit a tricky post situation, or the client wants a last-minute teal-and-orange pass on their tech founder doc.
On bigger jobs at A List Creative, we’ll occasionally roll a custom look with the DIT and use that on the monitors, so everyone’s on the same page. Still, we never commit that to the recorded footage. Give post as much flexibility as possible, especially when shooting log or RAW. Your colorist will thank you, and so will anyone who’s ever watched a corporate talking head with emasculated skin tones thanks to "WDR-709_Standard."
For leaner shoots, you can still use factory LUTs as viewing proxies—just slap a sticky note on the monitor to remind yourself it’s not the final look. If you absolutely must turn around deliverables same-day, then fine, pick your favorite in-camera LUT and live with it. But don’t pretend it’s the gold standard.
Edge Cases and When They’re (Barely) Justified
Fine, I get it. There are those low-budget realities where the intern is editing, the client wants rushes in twenty minutes, and nobody’s ever heard of DaVinci Resolve. Built-in LUTs will save your bacon in those rare emergencies. Same for multicam panel discussions, where nobody cares as long as every frame is exposed and not green.
But as soon as you’re shooting anything worth more than a lunch budget, it’s worth investing in a color workflow that isn’t dictated by a marketing department in Japan or Munich. Every time I’ve skimped here, I’ve regretted it. Every time I put in the extra prep, it’s been embarrassingly easy to deliver footage that actually looks expensive—and doesn’t get rejected in V4.
So trust the built-in LUT if you must, but you can do better. Your footage—and your blood pressure—will thank you.
