lAdjusting by luminance source (MODEL L-2101)
The MODEL L-2101 luminance box should be used. However, ones with color temperatures ranging from
2600K to 3000K (measured value of the Minolta color meter) at EV 15 can also be used.
'@ Luminance boxes with long-wavelength cut filters and lamps with cold mirrors cannot be used because of
measuring errors. (Example : MODEL L-223)
@ When no luminance source is used for the adjustment, employ method B on the next page.
