I have an upcoming studio shoot in which I want to do a large booklight key (with the usual spacelight cyc wash in the background).
Now, I usually do this a certain way but I'd like to know if the same can be accomplished in another way. What I usually do is blast a 12k (Arri t12) into a 6x6 ultrabounce then into a larger 12x12 silk or muslin (depending on the shoot).
My question is what is the comparative difference between a single large source blasting into the bounce then into the diffusion vs multiple smaller sources (let's say a series of 2k open faces) filling the bounce frame then going into the diffusion? Is it more common place to utilize the bigger single source?
