Hello there!
Have anybody worked with this situation?
What would be better for skin tones? Tungsten or HMI?
What would be better for keying?

I was choosing HMI for the amount of power instead of tungstens units


Cheers!

If digital, as it's natively around 5600K balanced on the chip, I recommend daylight heads. If you're on film; then I recommend whatever the balance of the film is. Consequently, Green screen is substantially better for digital as it's the most abundant "color" on a bayer chip and blue screen for film as it's the sharpest layer.

Adrian,

 

Thanks for your reply, it has to be blue because of the colors of the wardrobe that definitively will carry some green items,

 

also will work in digital.

 

Thanks

My pleasure; and  yeah, Blue works fine for digital as well just one of those little added knowledge bits lol. Been awhile since i've seen/done BluScr though (cept when i'm on a windows 98 machine lol)

However blue is also the grainiest layer on tungsten-balanced film, another argument for daylight-balance for both digital and film for chromakey...
