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 Luxi™ 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 in kelvins and green/magenta tint in Wratten/CC values and giving you corrections to or from your target color temperature (color metering requires iOS 8+, and Luxi or a gray card).

> Measures 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 (recent devices, iOS 7 or later), 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.


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

Cine Meter II does NOT work with Lumu Power.

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.

What’s New

Version 1.21

• Low Light Mode switch in Settings, to extend low-light sensitivity by 2.5 to 3 stops. Low light mode lets the camera's shutter speed drop to 1/3 or 1/2 second for better light gathering. In low light mode, images may be blurrier in dark scenes, and the meter may respond more slowly in bright scenes.

Most recent upgrade is broken

I love this app. To have a color temp meter for $25 + cost of a little white dome? Amazing!

Only thing, the app received an update a few days ago, and now it won't open. At all. I deleted it and downloaded it again, in case I had a rare corrupted copy — but nope. The fresh download is busted, too. There was a catastrophic bug that shipped in the last package.

I hope you are on it, Adam Wilt. I won't give you one star for a bug that will hopefully get fixed immediately (since low stars are forever). But, well, it's a zero star app at the moment, because it's working zero percent. Please fix soon.

Developer Response ,

I've downloaded the store copy on several iPhones, iPads, and iPods touch, and it's working normally on all of 'em; I can't make it crash for trying, whether they're updates or fresh installs, on my account or on others. PLEASE contact me directly (cinemeter@adamwilt.com) so we can fix this! (Also, did you try the other troubleshooting steps at https://www.adamwilt.com/cinemeterii/support.html ?)

Great tool!

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!

The best $25 I have spent in recent memory

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.
