I recently was given a Rolleiflex 2.8C and am extremely excited to get back to film. The camera is in excellent shape and everything works fine. The only flaw that I could find at all was that the taking lens has the very faintest of what looks like a smudge. I went to the biggest photo store in the area and after quite a bit of digging in the back fridge the sales associate produced the only roll of 120 film that they had left, which was Kodak B&W TMax 400. I took it home, loaded it up and ran a test roll in the back yard. It has been a long time since I shot film and I did not have a light meter so I shot some at f8 and some at f5.6 with a shutter speed around 100 (sorry if my tech talk isn't up to par, I'm extremely rusty). I'll also mention that my backyard is partially shaded but there was lots of early evening light. I picked up the developed film today, not expecting perfection due to my exposure guessing, but I'm not sure what to make of the results. Half of the pics are what I expected - a little on the gray side and grainy but otherwise okay. The other half of the pictures are a different story. The bottom half of these pics look as expected, but the top half varies from very light to completely white out. It's on the negatives as well. Is this due to bad film, bad processing, or something with the camera (like maybe a light leak or the smudge on the lens or something more sinister?).
