YongLee Share Posted September 12, 2020 (edited) who can tell me how many footlambert the white bars used to determine the contrast in N color bar signal? I remember seeing in a photographer's manual that it was written 35 foot candle, but the foot candle was a unit of illumination, not a unit of brightness . If you measure brightness, how many feet of Lambert should it be? Edited September 12, 2020 by YongLee Quote Link to post Share on other sites
Bruce Greene Share Posted September 12, 2020 In a calibrated display, in a darkened room, white should be 100 nits or 29.2 foot Lamberts. 1 Quote Link to post Share on other sites

Bruce Greene Share Posted September 13, 2020 HDR? That will depend on the range if your display and the HDR standard you are grading to. Suitable HDR displays currently cost about $30,000. Do you have one? Quote Link to post Share on other sites
