Valles_Marineris-20071228a-PCF-LXTT.jpgBetween Marineris and Labyrinthus... (Darkened Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)59 visiteDa ammirare, a nostro avviso, la "resa visiva" del contrasto fra zone esposte alla luce diretta del Sole, le zone in penombra e le zone in ombra (come quelle alle spalle della montagna che domina la porzione Sx del frame).
Ricordate, poi, che la Regola Aurea della fotografia spaziale recita quanto segue: "Quanto più il contrasto fra zone in luce e zone in ombra è netto, tanto minore è l'influenza dell'Atmosfera su quanto ripreso".
In questo frame, come in molti altri, il "contrasto" c'è, ma NON così netto come si vorrebbe (questa, almeno, è la nostra opinione).MareKromium
