Spent Tuesday in the hall with a lighting tech, a nice patient man named Vojta, and we moved four spots around like we were arranging flowers. The piece is eleven metres of scaffolding, old window frames and about two hundred kilos of scrap sheet metal. In my studio, under one bad bulb and a north window, it is a thing that has weather. In the gallery, lit evenly, beautifully, professionally, it is a display. Everything readable. Nothing to walk into.

I know the correct answer. The correct answer is the light is part of the work and I should fight for the light. But I have fought for the light before and lost, and then the work went out into the world looking like a showroom sample and people wrote nice things about the craft. The craft was never the point.

What I actually wanted to ask, and what I have been avoiding asking for twenty years: how many of you build the piece for the room you know it will be shown in, and how many build it for the room in your head and then spend the install week apologising? I have done both. The first one sells better. The second one is the only reason I still do this. Vojta is coming back Thursday and I have to decide which man I am this time.
