Pre-Exposure Warning
The Camera Profile is displayed on the analog scale when the Mid.Tone is set to:
EV scale Measurement scale (Aperture, Shutter Speed)
Indicators (arrows) change their color based on the stored profile compared to the measured values
- - - Within dynamic range/clipping point
- - - Out of clipping point
- - - Out of dynamic range
The analog scale shows the gap (in number of f-stops) between in and out of dynamic/clipping range

What is Exposure Profiling?Each type of digital camera sensor has its own unique way of responding to various exposure conditions. These conditions often change the accuracy of the rate ISO and the dynamic range.
