If only it would work on a projector - the images are well worth a look.

He's either on vacation, or there must be something wrong with the special device that alerts him of these posts.

Maybe not, but I think its a useful discussion. Maybe thats exactly what we want, but although I can't find the words, it seems that there is some relevance that no information between 0.000 lux and .700 lux is ever present in the material.

There are just mean people out there:)

Nothing to stop you talking to them Kenland, their number is on their website.
With a greater than 8bit display, the number of levels available are so huge, that the problem of the number of steps wasted between absolute black and the cameras lowest light register becomes a non-issue. There are plenty of increments left over in a 16bit per channel system :)
|REC.709 calls for an absolute black level that is darker than your 200k:1 level (since it calls for no light)|
|but doesn't the gamma+tail start at zero?|
