In an effort to predict colour changes on a wooden sculpture, I am seeking information on the effects of unfiltered daylight on yellow cedar, a common medium used by indigenous Northwest Coast sculptors. Microfade testing cannot help in this case, unfortunately, since the equipment available to me does not include UV. Does anyone know whether this wood darkens, lightens, lightens then darkens, or vice versa? I would like to digitally alter photos of the sculpture to show the effects of photodegradation in order to help the artist and curator decide whether the changes are acceptable.
Thank you in advance for your help!
