Hi, I need help here. I suppose to take grp photo for ard 12 person. Inside a function room, there will be a event backdrop behind the row of people, but the sid eis a full glass which sunlight and shine in but there is a transparent curtain.
I'm using Nikon D3x with D900 flash light and 2 speedlight (studio light), when the speedlight is set 1/1 and my aperture f11 or f9, 1/60s , ISO 100, the shots taken is dark like without flashlight (my flash and speedlight is working fine). It seem not logical but when I set the speedlight to 1/32, f4.5, 1/60s and ISO 100, it seem to be brighter. Butthis is not logical rite?
