Thanks Trevor. Its better but I'm trying not to burn out the area around the Humunculus. Might have to give it another run tonight if the weather stays good. More subs but shorter. Think I'll cut it back to 2 mins or so, as the LP here is worse than I thought. Looks pretty dark, but the camera says otherwise.
Had another play with the RAW's, got a bit more out of them, but still overcooking that central area.
