I started re-shooting some artwork today after a bit of a false start yesterday. This is one of the larger pieces I want to re-photograph so it's a good one to test the rig on. There is only just enough space to get everything in the room!
I have two 300w studio flash units with adjustable output, and two decent sized soft boxes (70 x 100cm). The stands extend to 2.6m. The flashes were second hand from ebay. It should be good enough for most things I will need to do. I generally prefer to photograph in daylight - which I will continue to do when I can - but at least I now have an option when it isn't possible or practical.
