Arrange the stages of installing an exhibition in the order they are carried out.

1. Write a condition report for every work before it leaves the studio
2. Decide the sequence and where the viewer enters
3. Set the common centre line and mark the wall
4. Hang, using fittings rated for the weight with a margin
5. Set the lighting to the level the most vulnerable work in the room allows

The last step is decided by whichever work in the room has the lowest limit, which is why a single watercolour hung among oils drags the whole room down to 50 lux. Knowing that in advance turns it into a curatorial choice — separate rooms, or accept the level — rather than a discovery on the last afternoon.
