Thanks all, some very valuable advice. Until know I have just used household lamps, and not very good ones to be honest, or not for this purpose anyway. I think a permanent light source would suit me better than flash, although as Terry says, using the logic of KFB theory.
I have a series in mind that I want to do and will need to sort out the lighting for it, which will be the easy thing, the difficult bit will be convincing my wife to sit for it. I may have to go shopping for shoes for her first! (I know that probably sounds sexist or somesuch, but she really does love shoes)

Everything will be a bit makeshift, a dust sheet sounds like a good idea, and those supports Mike mentions. Reflectors seem like a good idea as well, the emergency blanked is a good shout. Some really good thoughts, thanks you.
