Re: Day to day fluctuations in continuous studio lighting

Are your light power levels the same from day to day to day?

Are your camera settings identical from day to day to day?

Are you controlling the VIEWING & comparison environment where you sense the color shift? Down to the same color shirt as you sit in front of the computer...

AC power(voltage) may be fluctuating depending on the area's demands thru the day.. maybe that changes things.

CF lights tend to have an uneven spectral distribution over the AC waveform cycle.  If you're capturing just a portion of the AC frequency (50 or 60 Hz, depending on your country), you may be missing out on some portion of the spectrum in different shots.

Just some thoughts!
