Abstract: A photographic print and developing tray which is designed to removably connect to the bottom of a base of a photographic enlarger. The photographic enlarger is to utilize a photographic transparency which is to be projected onto an unexposed photographic print paper mounted within the photographic print and developing tray. The photographic print and developing tray defines a tray housing upon which is mounted a removable cover. Associated with the tray housing is a locking arrangement to tightly secure the cover to the tray housing when in the closed position to prevent the conducting of any light within the internal chamber of the tray housing. There is also a separate latching means connected between the tray housing and the cover which becomes engaged when the cover is located in the closed position. The internal chamber is designed to receive a quantity of photographic print developing liquid. The liquid is to be supplied to the internal chamber through a separate container.
