01 Examination

Put the light down flat and the picture becomes an object.

A conservator examines a surface by dropping the lamp almost parallel to it, so every ridge of paint throws a shadow. Impasto, canvas weave, old fills and craquelure all appear. Drag across the plate to swing the lamp; lower it to graze the surface.

Relief

Surface normals are derived from this single photograph by shape-from-shading, as a reading aid. A measured relief map requires photometric stereo — several exposures under known light positions — which we supply with the full condition report.

03 Viewing room

Scale does not survive a thumbnail.

The trade still decides what a picture is worth by standing in front of it. This is the sale hung on real walls under real gallery lighting, at the works' own proportions. Drag to look around the room.

The three-dimensional viewing room needs a desktop browser with WebGL. Every lot can be examined individually from its catalogue entry.
