Update:
The Luxi's are sold out and they don't plan to restock, but this method is still possible: Place any generic light dome replacement over the iPhone lens and calibrate as shown in the video (linked below). You can even hold the expodisc over the iPhone lens in the same manner. It's all the same as long as its a translucent natural grey. There was nothing special about the Luxi except that it had a convent clip.

Here's a method for measuring and setting white balance that we've been doing for several years. I know that many of you love to balance by eye, and if that's working well then there's no need to change. But I've always had more consistent results and a better image quality by using the ExpoDisc and more often Cine Meter II with the Luxi.
Some Notes:
- Remember to put your magenta shift back at zero when you've finished shooting in green light. This can burn you if you're not careful.
- It’s rare, but if the green shift ever reads higher than your camera can dial out, leave it at zero and do a custom white balance with a grey card or expodisc. Canon and Sony will remove more green this way. But don’t add magenta shift to a custom white balance because it will shift it in addition to the already neutral image.
- You're not measuring the light but your position to the light. That's why everything outdoors is not 5600k. If you’re using mostly shade, 5600k will be too cold. So try to always measure from the position and perspective of your subject on the side that your camera is facing.

If the Luxi's are out of stock, you could use this as the light dome, but it's not ideal because it won't hold itself to the phone - www.bhphotovideo.com/c/product/490665-REG/Gossen_GO_4497_Incident_Diffuser_Dome_for.html

[@thefilmpoets]

Sweet. Have fun with that thing!

[@thefilmpoets]

Just had a friend calibrating for her Sony camera. She said the max magenta that could be dialed out was +7m but Cine meter couldn't go that low on the tint gain adjustment. +9 was the max. The solution is to higher, all the way to +70G on the tint gain. So +70g on Cine Meter would mean to dial in +7m on the camera. Think of it like 7.0, not 70 and it'll make sense. The tint gain adjustment in Cine Meter is just a scale setting. Like reading kilometers or mph, it's the same speed, different scale.

good advice. I have found another video somewhere on youtube that relies on auto balance but with auto balance lock button to keep it from shifting while you shoot. you can use grey card and auto balance works pretty good with that. obviously this method got its limitations, I like the fact that with your phone you can walk around and get light measurements ahead of time. thank you for the info!

[@Jared10112]

Bro... you have helped me a ridiculous amount. Even just watching your wedding videos has inspired me when editing my videos. Your films are top notch! Do you find doing this before every shot can become cumbersome and take you out of a situation and probably miss/shoot the shot differently. I tried this method at a wedding I shot last weekend and it felt like I was cramming too much for something I could change in post. Idk 🤷🏽‍♂️ I just feel like a lot of time is consumed using this. I could just be doing it wrong though 😅😂

[@thefilmpoets]

It's an extra step for sure. I've found the more I do it, the easier it becomes, but you can always do both until you become used to measuring ahead of time - measure when you have the time and eyeball it when you don't and fix in post. I'm always measuring before the shots. I walk into bride prep and measure the middle of the room for general girls sitting around shots, and remember that number - measure the window light for makeup, etc. Then I just go between those two depending on what I'm shooting. Not re- measuring each time. Hope that helps!

[@norgerichard]

You are a perfectionist. I like that.

[@JoshMiles]

I don't shoot weddings, but this is great advice for anyone shooting in different scenarios. I had to watch that green/magenta calibration part back like three times 🤯 but now I think I understand. I've had a few other far more expensive light meters on my list, so I'm really excited to check out this Luxi meter!

[@thefilmpoets]

Thanks Josh. Yea the point of the green calibration is to make it so you know how much green your camera can actually dial out. Sometimes you’ll actually go over that number. In those cases the expodisc and custom white balance will take care of it. For some reason most customs white balances and remove larger amounts of green than manual. I’m sure that really expensive meters are more accurate, but I’ve been pretty happy with the luxi/Cine meter combo. -Matt

[@JoshMiles]

Thank you for showing us the correct way. for fast pace job, I always leave the white balance at 5600k & throw some 5600k light for indoor. I know it is not accurate but it's way better than auto white balance. I"m wondering how other videographer did their setup ?

[@davidventura8350]

This video is excellent, I’m definitely going to try this out! I’m also just curious, how would you white balance with an ND or VND filter? 🤔

[@thefilmpoets]

A good ND should be neutral. Just like a good lens, it should have no color cast. But many have a slight green shift, especially the VND. If you know you're going to use it all the time you can do one of two things : 1. Measure the shift of the Nd by placing it over the Luxi and noting the shift. Then dial that shift out when using it by doing the opposite in camera. 2. Calibrate the Luxi with the Nd over the the dome, if its a VND set it to the midpoint. This would give you a permanent offset in the measurements and keep you neutral. Generally slight color shifts in lenses are just part of the character, and you go with it, but if it's coming from an ND you'd want to fix it. Hope that helps. -Matt

[@thefilmpoets]

Update for Android users - So after a lot of searching I found a solution (kinda) - Filmic Pro on Android has an auto white balance feature that shows the kelvin temp and tint. It can't be calibrated though, so you'd need to either use the Luxi (which isn't calibrated itself) and do mental calibration to offset what filmic pro sees, or hold a calibrated grey card or expo disc over the phone lens. I've found it to be pretty accurate, but consistently about 10% too cold. But it could work - see this video : kzbin.info/www/bejne/p5mZpYBmiqd5bsk

[@kirillarefiev6126]

You have to point it near the subject you film. It has light sensor, so it needs to check the light at the same point where you focusing. (in this tutorial he points it near the bride, check it again)

[@apost099]

In mixed light situations do you ever hold the luxi so it’s pointing straight up so it samples all the light?

[@thefilmpoets]

Yea I'll play with that sometimes. If its a true mix of light temperatures, like a dance floor at dusk with some tungsten lights hitting it but also some daylight from windows, I'll stand in the main dance position and let whatever falls onto the luxi tell me the number. like a window-lit interview with tungsten lamps in the background, I'd color balance for the key light of the window and let the background lights fall wherever the end up. -Matt

[@francisgeorge2982]

Wow this is super helpful. Thank you! I just wish they made Cine Meter II for Android 😭 Any comparable apps you'd recommend?

[@thefilmpoets]

[@thefilmpoets]

It really is a pain. But that’s why it’s not $1800 like a light meter with good kelvin and tint measurements. Also way smaller.

[@AnthonyMoreschi]

This great but I’ve noticed that dialing in kelvin on different camera brand’s doesn’t always match. Even a c70 & a c300 MKII in clog2 don’t match perfectly. I’ve now switched to using a gray card to custom white balance all cameras and they definitely match perfectly while reading at slightly different kelvin temps.

@@thefilmpoets definitely will do.

[@Mistervaluable]

Just throwing this out there, but the developer of the Cine Meter II, Adam Wilt, responded to a review by saying "Yes, a $25 app running on the $15 camera module built into a phone needs calibration for best results! For color, you can get a spot-on incandescent source (a light bulb) for about $2. For exposure, use any other light meter or camera that has an exposure readout. You can also calibrate by taking a reading, shooting a gray card using that reading, and measuring the resulting gray level in the image..." (I'd assume by taking that image into Premier or other NLE and using the white balance eye dropper tool to thus measure.)

[@VoyageurMotionPictures]

Thank you so much for the amazing video!! After trying many times and watching the video many times, I'm having trouble with the green/magenta. I only ever get a reading of 0 +G or 0 -G. Even when placing the green sheet over the luxi, I only ever get 1/4 +G. Any thoughts on what I'm doing wrong? If you have time for a reply, thank you!!

[@xkben90]

Just bought the Lumi and the app. Thanks for the tips!! I have a question about white balance in general. Are you always trying to match the same kelvin number to what is there? For example, if it is 5500 kelvin outside, do you ALWAYS try to match 5500 kelvin in camera? And if so, what is the reason? More specifically, if you wanted warmer colors, why not change the kelvin number in camera instead of matching the “correct” white balance and changing the color in post?

[@thefilmpoets]

In general I'm trying to make white look white while shooting and then adding creative color grading afterwards. There are a few reasons : 1. I can't decide on a creative look for the day until I've witnessed the wedding and seen had a good feel for the look l I'd like. 2. Even if I wanted to, there's no consistent way to implement that through kelvin temp. If you want it to look "warmer" how do you do it? Add 400k to every shot? Doing that will look different depending on the measured color temp. Adding 400 kelvin to a shot that measures 3200 kelvin will look MUCH warmer than adding 400 kelvin to a shot that measures 5800k. 3. You can always do a global creative grade afterwards, and it's more accurate than guessing throughout the day. Our wedding film from Mexico is very warm but was shot neutral. - kzbin.info/www/bejne/jp3biYh3n9J6qbs Hope that helps. -Matt

[@patrickfalls6819]

Great video! I used the Sekonic C700 this past weekend at a wedding, and the color temperature kept fluctuating on average by 300 degrees. The magenta and green fluctuated as well. If shooting rec709, wouldn’t this render inferior results to auto-white balance?

[@thefilmpoets]

It depends on the situation. If window light was actually shifting a lot it could have been from the sun going in and out of the clouds, etc. the visual change of 300 degrees of kelvin depends on what the base kelvin your measuring from. So 3,000 kelvin with a 300 degree change to 3,300 is a much bigger jump than going from 6,500 kelvin to 6,800 kelvin. Think of it more in percentage change and you may notice it's not moving as much as you thought. As far as auto WB goes, no I don't think you get superior results. the auto WB is reactive, so it has to change only after the light changes. It also has to have a natural reference point, otherwise it will be off, and it's constantly drifting, so correcting in post makes it a moving target. But I do agree that in an un-controlled lighting environment, there will always be trade offs and shifts in light, so it's best to try and control the light as much as possible. -Matt

[@ramymelhem]

Thanks so much for this video. Would buying a dedicated light meter be just as good? If so, are they all pretty much the same?

[@thefilmpoets]

light meters don't do color temp, you need a spectrometer. But yes that would work. Downside is that they are around $2,000, and are one more thing to carry. I prefer using the phone becuase I already have it with me. Unfortunately the discontinued the luxi, so you you'd have to by a light dome and place it over the camera

I can't get the green gel before my next shoot, will the green/magenta colors be significant if everything else is balanced?

[@thefilmpoets]

You could just ballpark it. The green magenta cast will tell you which direction to go, and then try to get it right by eye.

[@ReggieSoares]

Question, after you done w the green gel calibration, you go back to the camera setting and move the magenta from 9 back to zero ?

[@thefilmpoets]

Yes, put it back to zero. Now when you’re shouting outside, it will not show and green or magenta tint, so just set your kelvin. But the next time your indoors and the window has green tint, it’ll read something 5600k +5G - and THEN you put the magenta in at +5M. Just be sure to take it back out when you leave that light or all of your shots will be magenta. -Matt

[@ReggieSoares]

Thank you so much

[@joshuabirman4709]

Have you ever tried out the Lumu Power meter for iPhones?

[@thefilmpoets]

One of my second shooters had it. It worked well and matched up to my luxi pretty closely. It's a good option that doesn't need calibration, just figure out how the green shift scale lines up with your camera.

[@afilmcompany196]

Have you guys used a sekonic c800

[@thefilmpoets]

No but I'm sure it's the best tool for the job. But it's just not practical for us to carry at a live event.

[@ScottFilmCompany]

To clarify...when calibrating on a sunny day at noon. Do we just set the CCT to 5500 or set it to the reading on the meter the sun is giving?

[@thefilmpoets]

You set it so that it reads 5500k when direct noon sun is hitting it (no clouds in the way)

[@NowyKurs]

That's so much hustle. Good if you have time on the movie set but not really in the real scenarios on the weeding day. That's obviously in my view and understanding, and understanding veries. With modern camera auto WB works well but also manual Kalvin temperature works pretty fast and easy. You can obviously change this easy in camera depending on location and your camera screen will remind you quick. If you don't be perfect (not such things exist in universe, keep this in mind) you can do some tricks in post production and you sorted. You dealing with moving image keep this in mind as well that most of your viewers would watch this on different devices and you don't have options to set them the parameters of display. If you a colour blind or have some other issues with vision than photography and videography might not be for you. Keep it real and simple to focus on your work rather then overlord yourself with extra task. That's my view.

[@benfairhurst4721]

How come you use the front facing camera? Is it just so you can see the results as you wander around with it?

[@thefilmpoets]

You can setup either camera, but I do like to see the readings as I hold it out.

[@matthijshols]

Hi Matt, Great video as always. One question about Luxi, I saw that you are using the front facing camera and from my experience the iPhone's screen brightness affects the reading. How did you overcome that? Kind regards, Matthijs

[@thefilmpoets]

I try to have the luxe position perfectly over the camera so that there's no screen involved. I suppose you could do a test as you raise and lower the screen brightness to see if its affecting it. To eliminate it totally, you can select the LUXI setting for the back camera and disable the front one, but it'll change the orientation of the phone as you use it. -Matt

Meanwhile I have found out that this issue actually only occurs with the Luxi developed app. That app comes for free, but it seems that the developers don't use their own product as they don't leave the top of the screen deactivated like Cine Meter 2 does. In other words, if you use Luxi as a spectrum color meter (and Light Meter) with Cine Meter 2, you should be fine 😆 See what I mean here: share.icloud.com/photos/0_5Ot7VaBNJMhXvztuYR-8m-Q I've reported this behavior and as soon as they have fixed this, I will remove my comment.

[@thefilmpoets]

@@matthijshols Yea I never messed with their app! Good find.

[@the_bad_visuals]

Can you someone explain the process of in camera calibration (G-M shift)? Is it a one time thing? Or we have to adjust M-G shift according to what the luxi gives us at the time of the measuring? Any recommendation for Sony A 7 series?

[@thefilmpoets]

You calibrate the luxe to match your camera only once. Then when you measure the WB, you enter the g/m into the camera. you do the opposite of what's shown. If it says +3G, you put in +3 magenta in camera to dial it out.

[@the_bad_visuals]

@@thefilmpoets Thank you very much for sharing. I hope one day you offer classes so we can all learn from you.

The best white balance video I've seen! I'm clicking on the link to the Luxi right now though and it says it's out of stock. I'm curious to know if it's being sold anywhere else, or if there has been an update? Thanks!

[@thefilmpoets]

But my wife has used the expo disc over the iPhone camera along with the cinemeter app with good luck as well. calibrate it just like you would the luxi. Only downside is it takes two hands.

[@yoursalwaysphotography459]

@@thefilmpoets So we can use the app without the expo disk?

Hi do you know if this app exist for Android phones? or if there is a similar app for that OS?

[@thefilmpoets]

Update for Android users - So after a lot of searching I found a solution (kinda) - Filmic Pro on Android has an auto white balance feature that shows the kelvin temp and tint. It can't be calibrated though, so you'd need to either use the Luxi (which isn't calibrated itself) and do mental calibration to offset what filmic pro sees, or hold a calibrated grey card or expo disc over the phone lens. I've found it to be pretty accurate, but consistently about 10% too cold. But it could work - see this video : @

[@apost099]

My Sony camera goes down to a magenta of 7. I followed the directions in the video but when I adjusted the tint gain I had it on its lowest setting and it was giving me a reading of 14. Would that just mean that whatever the Luxi gives me I have to half that to put it into my camera? For example, luxi gives me a G5, I plug into my camera M2.5?

[@thefilmpoets]

exactly.

[@the_bad_visuals]

Hello Adam, did you also get a greenish look before the in camera calibration too? What is your M-G shift setting to balance it? Thank you.

[@MichaelAres]

So you can't set the magenta and green tint calibrations just on the app with the luxi? My Nikon Z6ii doesn't have RGB waveforms to display.

[@thefilmpoets]

If it can’t display RGB, record a video while doing the green gel thing and make a note of each time you fold the gel over. Dump the video and look at the rgb waveform on your monitor. Note which number of folds the green channel is even with the red and blue. Then use that as the number to go over the luxi for calibration.

[@screammachineman]

@@thefilmpoets I cant get my Sony A7siii to display the channels so I'll have to do just this.

Is there a way for doing the calibration without the green gel? Seems difficult to find it where I live.

[@adrienpayet]

@@Musicaadorecchio I think that if you buy 6500K bias lighting from media light that don't have any color cast, it will be easy to calibrate !

[@thefilmpoets]

@@Musicaadorecchio The green tint calibration isn't exactly calibration, it's just gain setting. So that means you could technically do without it, and when you're luxi reads some random green number, you use a grey Gard or expo disc and figure out that +20G means to dial in +5M in camera or whatever. You'll just have to do the mental math every time. I actually did it like this for a while.

[@lukshful]

any android alternative app?

How come the dome meter doesn't pick up all of the cool blue sky when you point it at the cloud free blue sky dome at noon?

[@thefilmpoets]

You’re letting the sun hit it directly and it’s much brighter. You can test it by shading the dome from the sun with your hand. You’ll see the kelvin temp jump from 5500k to 8500k or so. So the answer is the sky does hit the dome, but an un-blocked noon sun plus a sky should be about 5500k combined.

[@defdac]

@@thefilmpoets aha, the extreme difference in intensity drowns out the sky. Thanks!

[@GeorgeAtanassov]

This is a good method if you use the same camera but if you shoot with too different cameras? Also Canon custom WB method is very cumbersome.

[@thefilmpoets]

If you shoot with different camera the kelvin WB would still work, you'd just need to know the scale of the green /magent shift of the other cameras. - for example my R5 goes to +9 magenta, my c70 goes +20.

[@GeorgeAtanassov]

@@thefilmpoets So if CMII shows you +4 on green and is calibrated to the R5 would you then put about -10 on the C70?

[@thefilmpoets]

@@GeorgeAtanassov that'd be a good start. You'd really need to test to nail down the exact number though, but ballpark with green shift is better than ignoring it.

[@CodyScott]

It takes more time taking a custom white balance photo than pulling out your phone, adjusting your tint and Kelvin? Just curious. When you snap the custom white balance photo, does it matter what your white balance is set to when taking the reference photo?

[@thefilmpoets]

It's probably about the same amount of time but its just more cumbersome. And no your current wb doesn't affect custom WB.

Glad to hear it. This shows in stock for me, geni.us/Luxi so I'm sure its available in certain areas. Also theres a Lumi, calibrated disk that plugs into the bottom of the phone. It works well but you'll need to figure out the scale of the g/m shift compared to your camera.

Have you ever checked the color temp in the app, set the WB in cam, and looked at your monitor and thought this is horrible? I have run into that situation a few times and just went with what my eyes were telling me. I was too scared to trust the app.

[@thefilmpoets]

As long as you've calibrated it properly that should be rare. But I've seen it freak out under strange LED lights at a reception. 99% of the time it's looking good to me. But if it's just crazy out of whack, just go with your eyes and then do a more tests at home to see if you can trust it. It REALLY needs to be a clear day when you calibrate under sunlight. Run a few test setups like shooting in full shade, window light, etc and see how it goes. -Matt
