How do I light groups of people versus one/two persons

[mike barlas]

Hi everybody,

I have a question, how do I light groups of people versus lighting one/two persons?
Theoretically or practically.( All lighting will be tungsten)

In my case, I am lighting close ups one/two persons with a key 1k Arri diffused and a fill 4'4 bank kino

For shots with 2-5 people, roughly speaking without time to test, can I flood the Arri more so it hits more people? Or fore go the Arri 1k together...

Instead bounce some light on to a 13x13 ft scrim I have (which is a movie profjector screen) with a 750 open face and an arri without barn doors as a key?

I could put the scrim up on two stands, and bring it back with rope to create and angle, but I won't have
a butterfly frame.

Cheers,
Mike

It shouldn't be any different,light sources are constant. You might need to use more powerfull sources as 750 bounced into 13ft is not going to do much

I have two 1k Arri's as well. I could get another 750.
