I should have double-checked first. From the spec parts you've quoted,
it seems there is indeed no 'disclaimer' on SMin/SMax. So, my bad.

Though, still, have you seen many actual use of these tags in the
implied sense? If you've test images that do use them this way, I'd be
very grateful for a copy.

In any case, when it comes to a recommendation for writers, would you
agree that recommending them to stick with the 'intrinsic' range of the
samples, as I explained it, is best and most likely to lead to good
interchange (as far as there is interchange of floating point image
data, at all)?


Best regards,
