Yo no disparo con la opción VVN activada así que no puedo comentar sobre la misma pero ojo porque
Rico Pfirstinger , sobradamente conocido por la cantidad de libros que tiene publicados sobre manejo de cámaras Fuji dice esto:
"NLV invokes a live view with an internal DR400% setting, so it can be up to 2 stops off (assuming that the camera is actually set to DR100%). Since the Fuji histogram always reflects the live view contents (not the RAW file contents), it too can be up to 2 stops off in the highlights with NLV on.
Basically, NLV is a no-go for any exposure metering involving the histogram (or even just winging it by looking through the EVF). Sadly, there’s no RAW histogram but one can get a histogram that is closer to RAW by selecting ETERNA and Shadow Tone -2 / Highlight Tone -2 in concert with DR100%."
