You’ll find the app’s readings–and the recommended exposure settings based on those readings–
underneath the rear camera image. We’ll explain how that data can be useful later, in the section entitled
“Setting Your Camera’s Exposure”
.
Luxi™ Mode
With a
Luxi™
clip attached to your device, the image from the rear-facing camera is no
longer displayed; it is replaced with a pair of slider controls which are used for
calibration (see “Calibration Procedure,” above). If you’d like to reset your calibration
to the original defaults, you may do so by tapping the DEFAULT button. Below those
sliders are readings for Exposure Value (EV) and Luminance (LUX); those readings are
most often useful for non-photographic use cases. If you are unsure of what these
readings mean, you can probably safely ignore them.
