English term

angular subtense

English to Serbian Tech/Engineering Photography/Imaging (& Graphic Arts) Colorimetry - kolorimetrija
"If this angular subtense is greater than 4° the
tristimulus values X10, Y10, Z10 calculated using the colour-matching functions of the CIE 1964
standard colorimetric system should be used. The same colour-matching functions and the
same specified white stimulus shall be used for all stimuli to be compared with each other."

U pitanju je ISO/CIE standard za određivanje veličina vezanih za boje.
Javlja se ovaj termin angular subtense kao i subtended angle koje nikako ne mogu da rasključim.
