Vol. 08 · One wall

Decide one thing completely.

Idea and artifactArchive

§1 · Rule

Decide one surface completely. Keep the rest quiet.

Most rooms are decided by accumulation, a little of everything until nothing is decided. One surface, specified completely, gives the room its position.

Method

Specimens are crops of site photographs in the archive. Colour is the mean of the sample area in sRGB, with CIE L*a*b* under D65. LRV is estimated from relative luminance; the photographs are uncalibrated, so treat it as a guide. Texture is the standard deviation of L* after light falloff is removed: T1 below 0.70, T2 to 1.00, T3 to 1.50, T4 above. Light falloff is the range of L* across the sample, a measure of the photograph, not the wall.
