Please elaborate. I don't get it. What has the frequency of the flourescent tube have to do with the cyan(greenish ) cast on film?
Yes, a longer exposure will give more even lighting. But what about the color shift?
By the way, Diablo was asking what filters to use when shooting with FILM.
yanyewkay, the operating frequency is how the flourescent works, 50 to 60 Hz, it is basically within, I think, 1 sec the light is switched on and off. Just imagine trying to switch a tungsten light on and off 50 to 60 times in 1 sec.
Ambient exposure is dependent on how long your shutter is left open if shooting at a particular aperture. So if the exposure is longer, hence more light the more even the lighting, as I am assuming as with any room lit with flourescent tubes there are light banks every few feet.
And if you are using strobes, they have to be corrected to daylight also, therefore, probably a cyan gel would be needed.
I hope this makes sense. Please correct me if I am wrong.
