Here Bob Bonis captured Brian Jones combing or adjusting his hair (as was often the case) in the mirror prior to appearing on stage or camera. Brian is actually standing behind Charlie Watts, in this photograph, who is taking a drink from a bottle.
The black and white images from the Bob Bonis Archive are custom silver gelatin prints, printed to order by the master printers at Duggal in New York. They are printed on double weight archival fibre paper and then selenium toned (an archival toning process) to increase the tonal range and ensure longevity. The term silver gelatin print is derived from the gelatin emulsion in the photographic paper, which contains light-sensitive silver salts that react to light exposure.
