Cine Meter: Time to throw away the light meter?

SEE the light: Cine Meter gives you an RGB waveform monitor and a false-color picture in addition to a cine-style light meter, using the camera in your iPhone / iPod / iPad.

• The light meter shows you your stop as a decimal value (such as f/5.0, good for cameras with EVF iris readouts) or as a full stop and fraction (like f/4.0 ⅔, good for cine lenses with marked iris rings). You can calibrate Cine Meter to match other meters to a tenth of a stop.

• 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.

• The 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 gives you *absolute* light meter readings, but *relative* picture and waveform monitor levels:

1) Cine Meter’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.

2) You can’t *preset* exposure or color temperature in Cine Meter. To compare exposures and colors, you lock Cine Meter’s auto-exposure and auto-white-balance settings while looking at a known good reference, such as a gray card. The picture and waveform monitor then show you levels and colors relative to your locked settings.

I was on a film commercial shoot when an AC sent me the link to this app. The director, gaffer and I downloaded it and compared it to both meter readings and dailies. This is not a gimmick or toy but a really accurate light meter! For 4.99 you’d be foolish not have this on your phone in case your meter battery dies or your scouting or just curious what a beautiful moment would meter at.
Would love to see foot-candles added.

Fantastic!

This is a great app. Very useful. I’ve been familiar with Adam Wilt’s work since the beginning of Digital Video. There is nobody I would trust more to make a great utility for shooters. Well worth the money.
