Mariner 10 color-filter mosaics. (A) and (H): CLR-filter radiance mosaics of Mercury during the outgoing and incoming first encounters, respectively, demonstrating the view from the spacecraft while each color-filter sequence was acquired, for context. (B)–(F), (I)–(J): color mosaics after processing and photometric normalization (see Section 2.1). Trimming and blemish masking leaves significant gores in color sequences.
