How To...

Check exposure: use the Y WFM to see where your levels are. You can use Wi-Fi WFM to watch exposure as your camera moves through a scene, checking for overexposed details.

If your iDevice supports false color, set the false color levels to show you over- and underexposure warnings, and/or use the green level as your target exposure value.

Check color: Use the RGB WFMs or the vectorscope look at color. When the camera is aimed at a white card or grayscale and is properly white-balanced, overlaid red, green, and blue waveforms will superimpose and turn white; on the vectorscope the center dot will be properly centered in the crosshairs.

When the camera is aimed at a bluescreen or greenscreen, you can adjust exposure while looking at RGB WFMs or color histograms, checking for the best separation between your key color and the subject’s colors.

Electronically-generated colorbar vectors should fall in the vectorscope target boxes at either the 100% setting (typically EBU full-frame bars, or the fully saturated red/blue/cyan/yellow patches on ARIB bars) or at 75% (SMPTE & ARIB bars). When shooting a DSC Labs OneShot®, ChromaDuMonde®, or ChromaMatch® chart with a “V/S Gain x 2” marking, use the 2x setting, and — in an ideal world — a perfectly set-up camera will put the chart’s vectors into the target boxes (this won't happen unless the camera is calibrated for standard Rec.709 color and gamma. Unless you’re using a broadcast camera this may not be the case; many cine cameras, camcorders, and DSLR-style cameras use different color and tonal-scale rendering, and the vectorscope pattern will not match the layout of the target boxes).
