I am continuing to test my new 600ex-rt.
Flash Setting at full power 1/1, 105mm direct flash firing at a piece of white paper.
Using ML v2.3 RGB spot metering, I needed to WB my camera to 6300K in order to
get all 3 RGB values to match.
This tells me that my 600 is about 300K bluer than a "standard" flash, which is at 6000K.
My real life shooting has confirmed my test. I needed to dial K about 300K higher than my
usual setting to get the correct skin tone. i.e. when I gel with CTS I used to need 3700K but now
I need to go to 4000K.
Out of curiosity, I pulled out a mint Nikon SB-80DX and tried that too. It is spot on at 6000K.
BTW, camera used was 5D2.
So I am just wondering if others r seeing this too?
