Alistair.. thanks.. I use 4 quantaray MS1 flashes.. one behind pointed sideways between 2 boxes.. 1 in front about 3ft high, 1 on the possum's left at ground level reflected on foamboard,, and one on the possum's right about 4ft up..All with sandwich bags as difusers.. Shot in the dark with a flashlight for focus..
John.. They groom alot..This one washes his face between each cookie..
I wouldn't say they are friendly.. but they are not hostile or defensive..They know very well I am sitting there and they grab their cookie and leave... They don't exactly come looking for food.. If I put something out and they smell it they come.. I rarely see them poking around looking for something that isn't there.
