## What is Cine Meter II?

Cine Meter II measures light and color, so you can light and shoot and know what you'll get. 

“Cine Meter II is an essential app for every cinematographer.”
      — Jon Fauer, ASC

“[T]he perfect app to have with you at all times.”
      — Roberto “Ganzo” Schaefer, ASC, AIC

It's a zoomable spotmeter with an RGB waveform monitor and a false-color picture. 

It's an incident meter using a Lenny Hat or other diffusion, or Lumu™ Lite attachment, with lux and foot-candle readouts. (Lumu Power is NOT supported, and flash metering is NOT possible.)

It's a color meter, showing color temperature and green/magenta tint, and giving you corrections to or from your target color.

Measure more than just shutter-priority or aperture-priority: calculate shutter speed, shutter angle, aperture, ND, or ISO directly.

• The exposure meter shows your stop as a decimal value (for cameras with EVF iris readouts) or as a full stop and fraction (for cine lenses with marked iris rings). Cine Meter II lets you use shutter angles – ideal for Digital Bolex and Blackmagic cameras – as well as speeds, and you can dial in ND filters and arbitrary exposure compensations. The spotmeter is zoomable up to 15x magnification (on devices that support camera zooming), using either the front or back camera.

• The waveform monitor shows you how light levels vary across a scene. You'll see how smooth and even the lighting is on a greenscreen or background, and find subtle hotspots and shadows at a glance. The waveform’s RGB mode shows you color imbalances in the image and gives you a handy way to check color purity and separation for chroma-keying. 

• False-color mode lets you define allowable contrast ranges, and see instantly which shadows are underexposed and what highlights risk clipping. 
_______________________ 

READ BEFORE YOU BUY: 

Cine Meter II is NOT a flash meter; it can't measure strobes.

Cine Meter II does NOT work with Lumu Power (the Lightning port Lumu), only Lumu Lite (the headphone jack Lumu).

Cine Meter II gives you *absolute* light meter readings, but *relative* picture and waveform monitor levels: Cine Meter II’s picture and waveform monitor do not use the *exact* exposure shown by the light meter (they are close to the meter reading, but can differ from it slightly). The picture and waveform monitor show you *relative* levels within a scene, not *absolute* levels based on the meter reading. 

Shutter speeds, apertures, and ISOs shown in Cine Meter II are for metering purposes only and do not control the shutter speed, aperture, and ISO of the iPhone camera. The iPhone camera uses whatever exposure settings it needs to capture a reading. Cine Meter II is a light and color meter only; it is *not* a camera simulator.

### 5/5 — Overall its great and surprisingly accurate

*2026-01-14*

My only concern: idk if there was an update recently but there is a bit of a glitch. Its not letting me control my aperture to tell the app what i would like to shoot at

**Developer response:** Cine Meter II can solve for shutter, aperture, ISO, or ND. Press and hold on the value you want Cine Meter II to solve for (its background turns gray), and then you can control the other values. So to control aperture yourself, press and hold on shutter (for example); then you can set aperture and Cine Meter II will show you correct shutter for that aperture.

### 5/5 — top lightmeter

*2025-05-24*

made for film and video, but also for analog photography with spotmeter function a very useful tool. More precise than others

**Developer response:** Danke schön!

### 3/5 — It is useful but not easy to use

*2021-06-21*

Please make some simple tutorial videos - the documentation is overly wordy, dense and confusing - and spread over multiple webpages. I’ve read the docs several times and still having difficulty using this to match a light to ambient. It’s more of an interface problem than a technical one. For example, I just want to point it at one light (or ambient) and then point it at another light and have it tell me what I need to make it match. Maybe it can do this but I cannot find it.

**Developer response:** You're right, I don't have a How-to for that. In a nutshell: measure one light; hit EXP LOCK, turn DIFFERENCE MEASUREMENT on, then tap the screen to lock the reading. While the lock is on, you'll see the difference between the locked reading and the current reading for both exposure and color. I hope to make some tutorial videos later this summer, but that'll depend on my work schedule, so I can't promise anything.

### 5/5 — Handy to have..

*2021-03-04*

A useful piece of software to keep on one’s phone. I’m an LD and occasional DOP and this is my go to app when I can’t find my sekonic meter!

**Developer response:** Thanks for taking the time to post a positive review. I appreciate it!

### 1/5 — A gimmick

*2020-09-04*

You need a 1500 $ color meter or a spot on incandescent source to calibrate the kelvin, you also need a professional light meter to calibrate the aperture readout. (To the best of my observation you cannot calibrate the lux/ Foot Candle output (AND the Lux read out is therefore incorrect as compared with my pro meter.

After I purchased I finally read the fine print in the manual that says “tint correction values shown are appropriate for full spectrum sources with fluorescent LED’s and other “discontinuous spectrum sources” you typically need 1/2 to 2/3 of the tint correction shown.

**Developer response:** 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; if you're shooting film, a bracketing test can give you your needed correction in one go, even using a fully manual camera without its own exposure meter. 

As the instructions say, lux/fc won't change as you adjust compensation, but once you set calibration they *will* change. And no, they probably will not perfectly match your other meter, as Cine Meter II can only be adjusted to 1/10 stop accuracy, not to +/- 1 lux or fc (none of my four calibrated pro meters perfectly match each other in lux/fc mode either, even though they match to within 1/10 stop in aperture reading).

Tint corrections are as accurate as with any other tristimulus meter (e.g. Sekonic C-500) but spiky spectra can fool all such devices. You need a spectrometer ($1200+) for more accurate readings; that's just the nature of the technology. See https://www.dvinfo.net/article/production/lighting/on-the-color-of-light-and-the-measurement-thereof.html for a discussion of the problem; see https://cinematography.net/LED-Camera/LED-Camera-Index.html for some real-world measurements.

### 5/5 — Very useful

*2019-01-27*

I matched this app with a variety of professional meters and it surprised me how correct the light meter and color temperature readings are. This is a reliable quick tool.

### 1/5 — Not for professional use

*2018-04-05*

Every time I navigate in or out of the settings menu I get a pop up window that says “no mail accounts.” Telling my to set a mail account on my phone. Of which I already have several. Very annoying. Not for professional use. Sad, because there are some good elements but overshadowed by poor UX design 😕

**Developer response:** That's not "poor UX design", that was a bug! It's been fixed: no more system pop-up when you enter settings and iOS thinks you don't have any email accounts available. 

Sadly, Mr. Wack never contacted me, so we weren't able to find out why his iDevice reports no email accounts when he claims he had several set up. That's not normal behavior and I wasn't able to replicate it on my own iDevices.

### 5/5 — The best $25 I have spent in recent memory

*2018-01-31*

For aspiring cinematographers (and probably professional ones as well) this is an amazing app. I will be using it regularly for my fledgling short film productions. Also great customer service. Five stars all around.

### 5/5 — Finally a colour temp meter for ios.

*2017-11-29*

Ive always wanted to read colour temperature. 
At this price its a dream come true.
Thanks Dev.

### 5/5 — Great tool!

*2017-10-05*

Cine Meter II is a very useful and accurate light and color meter for video and stills (both digital and silver).

It is an accurate spot meter (matches my venerable Pentax and my newer Sekonic perfectly after one calibration) and with a Luxi sphere works as an incident meter also (matches my Sekonic too, after calibration). Even better, it is a color meter, and seems *more* accurate than my old Minolta, matching my Kinos to cheap fluorescents. 

While this won't replace my meters (but it probably could) I don't bother carrying my older ones any more... 

The developer is super responsive too!
