Hi,
I've been conducting a little research about gel and I wasn't sure the relationship of transmission and stops.
Say, a gel has transmission of 30%. Does that mean that the gel reduces the luminance by 70%? If so, is it in lux or lumen or stop? (I don't have a firm understanding of these units so I might be saying random things) Also, is it helpful to know the transmission vs. wavelength chart?
I'd also like to know how the colour temperature of an original source affects the end result through gels. Is there a certain colour temperature that's most appropriate for gels? Or is it totally up to users? If you have your way of working with gels that'd be amazing to know as well.
Thanks!
