Didn't have much chance to get out this weekend so I played around with this. It's not quite how I wanted it but I have attempted this twice now and the amp is bloody heavy. This is quite a challenge, the 1st time I shot it I got too much light in the knobs and it looked like really bad bokeh. This time I don't have enough on them. I shall try again, but it involves moving the sofa as the room is long rather then wide.
