I primarily shoot medium format. Tmax 100, Tmax 400, HP5 and Panf 50. I had a bulk roll of 35 mm PanF Plus, a Nikon F100 with a 35 to 70 2.8 Nikon lens and decided to shoot it up. I developed a couple of rolls in Xtol and thought the base + fog to be high. Thinking that maybe my bulk roll was aged I bought another. Same issue. Shot a roll of 35mm FP125, same issue. Shot a roll of HP5, same issue. Delta 100 same issue, base + fog is high. To rule out the camera and lens I pulled a couple of feet off of the bulk roll of PanF in the dark, loaded a reel and developed same in Xtol. My densitometer gave me a reading of 0.36. I developed a roll of HP5, Tmax 100 and Delta 100 in Xtol, base + fog for all 0.08 to 0.1. Does 35mm have a higher base + fog than 120 ?
