Compagnie Francaise de Photographie Photosphere 1 (13x18)

{"overview":"The Photosphere 1 is a late 19th-century French detective camera produced by Compagnie Francaise de Photographie, taking 13x18cm plates. Today it is rarely offered, and the limited evidence suggests four-figure values at saleroom level when an example does appear, though a single historic data point cannot define a reliable current price band. Buyers researching what one is worth or how much it sells for should treat the figure as indicative only and watch for fresh comparable sales.","buying_guide":"Survival rates are low and originality matters: inspect the spherical lens housing for cracks, confirm the sector shutter still tensions and releases, and check that the plate holders and back are present and matched to the body.
