Cine Meter uses toolbar buttons to change what the displays show, and taps on the displays to change how it's shown. Cine Meter also has a Settings and Info page for less frequently needed tweaks, as well as built-in help.




Buttons: Use the toolbar buttons to change the displays:

Cine Meter's screen, with white balance locked



Tap different parts of the screen to bring up display controls:

Cine Meter's onscreen tap areas

  • Tap and Drag the Camera Picture to set the spot metering point. (Tap and drag only works when in spot metering mode).
  • Tap the False-Color Camera Picture to show the sliders for the false-color levels. Tap the picture again to hide the controls. (This tap only works in False-color mode.)
False color sliders

You can move the sliders while watching the image; the frame rate will drop while you adjust the levels, but you’ll still be able to see what you're doing.

To disable red or yellow, slide its slider all the way to the right (“above 100%”). To disable blue, purple, or green, slide its slider all the way to the left (“below 0%”).

The color logic is set up for an orderly progression of levels as shown above. If you get creative, you'll discover that purple has priority over blue and blue over green; all three have priority over the highlight colors, but red has priority over yellow.

  • TAP and HOLD the Camera Picture for two seconds to reveal onscreen data display, showing the camera's raw exposure data and a few calculated values, mostly for debugging purposes.
  • Tap the waveform monitor to show Intensity and Overlay sliders. These control the brightness of the waveform trace and the scale overlay. Tap the waveform monitor again to hide the controls.

  • Tap the Light Meter to show ISO Rating and Shutter Speed sliders.
ISO and shutter speed sliders

As you adjust ISO and shutter, the aperture will change accordingly. When you have the values you want, tap the light meter display again to dismiss the controls.

(This version of Cine Meter uses a shutter-priority meter: you set ISO and shutter, and aperture changes accordingly. This is usually what cinematographers want. Stills shooters sometimes want aperture-priority metering; version 2 of Cine Meter will offer this mode as well.)




Settings and Info lets you adjust settings and see program info and help:
