Son blanc est à combien de cd/m² ?
I make the conversion...
average 30 foot-lambert lum. white are 102 CD/m2
average 0.011 foot-lambert MLL ANSI are 0.037 CD/m2
http://www.unitconversion.org/unit_conv ... nance.html
Luminance values ??of Mackenzie HDTVtest Samsung F8000
white luminance 115/120 CD/m2 black ANSI 0.049 CD/m2
ANSI contrast 120:0.049 = 2448:1
with this contrast ANSI(2448:1)...
if we calibrate the luminance of white at 100 CD/m2
we have a BLACK ANSI exactly 0.04 CD/m2
After this to give the real value of BLACK ANSI
the Samsung F8000 properly calibrated, Samsung F8000
luminance measured with precision on chess ANSI, for direct entry (injection),
photometric detection, Samsung F8000 reports a black ANSI 0.037 CD/m2 !!!!!
Nico, thanks for your work, good day !
