well, this one says EXR can hold quite a big value per channel, way above 1.0f, obviously.  But for displaying (and encoding?) it must be compressed back to device-specific 0 - 1.0 range.

Thing is, if I open exr example file in gimp 2.10 and re-export it - it retain its above 100% values. It does not do this if I do this same roundtrip via cingg. So yea, we seems to be clamping at output.

and this article about Premiere tries to explain Scopes, and especially floating point vs 8bit input - Premiere apparently can limit this setting for scopes themselves....



so, HDR as used in ultra HD need some scope that goes to 10.000 (so, logarithmic I guess ...)!

something we should write somewhere in TODO, I guess .....

second technique about dealing with too shadowy video:

A CREATIVE USE OF BLEND MODES

This tip was suggested by FoodShipNine.

If all you want to do is control black levels, but let highlights float – which would apply to most web videos – here’s an option.

so, if we does not have this mode we probably should :)







Still not sure where, may be in fader? (where fade can't be more than 100%) . May be its time to ask Lion (Adam).
