Nice subtle tones Dunga. What film was it on?
My first MF was also a TLR (Mamiya C3). Not as portable as the Yashica though and tricky to hand hold but wonderful quality and a great instrument for learning with. I still have it but it rarely gets used. I really love 6x6 though and most of my MF gear uses this format although my travel MF camera is a Mamiya 7II.
