I noticed in the release notes that v 2.0.9 has Nikon HE/HE* compression support. Does this mean FastRawViewer is using the raw histogram for Nikon HE/HE* file format or is it using the embebbed jpeg?

HE/HE* is internally YCC, so similar to (higher bitcount) JPEG

Hi, could you clarify please. As Nikon's HE and HE* are based on TicoRAW which is patented, is FastRawViewer showing the histogram from the TicoRAW file or is it using the embedded image preview?

You can simply switch to JPEG-view mode (J hotkey) and compare histograms.
