Moin moin,
is there a way, to ,,measure'' the correlated color temperature of a
light-source (LEDs) without special equipment. GMC, Minolta etc. costs
about 1k Euro and above, for a non-profit-job a little bit to much.
Theres no need to be on the K exact..but approx. +-100K would be nice![:)]( "Smile :)")
I thought about taking a digital camera (e.g. Olympus E3), fix it to a
defined colour temperature, take a foto of the light (OK, look in an
integrating sphare, painted with BaS04, available are...
