Thanks for trying, Bob.
I guess it will be kind of tricky to get it to work.
The idea being for the room to be very dark, near to black, and get just the equipment displays
to show up bright and clean. As you said, a shot taken at night with all lights out (and curtains
on any windows closed) and enough exposure time to capture the (relatively) brilliantly lit
displays in detail is what will be needed.
And also, I was referring to a front shot of the speakers (just like the second picture
you posted in the first page of this thread, but a much darker room). So what you would see
would be these two dark barely-lit speakers towering over the amps with their clean cool deep blue
displays shining in sharp contrast.
I bet it would look GREAT that way.
