Snow is gray, not white. A 2% to 3% increase in development should correct it or meter at EI 320 in place of ISO 400.

I'm still struggling to load 120 film onto the developing reel. It keeps binding at 1/2 to 3/4 loaded on the reel. |
I know what you mean. That's one reason I went with the Ilford XP2 Super, so i wouldn't have to fool with loading film on the reel for development. The Super is developed at the local photo store, in C-41 (color) chemistry. I loaded a bunch of 35mm in my day, but that's a distant memory now! |

A member on Photrio (formerly APUG) was having similar problems, posted a picture of his 120 stainless steel reel and the center clip was bent out of shape.
I dislike plastic twist type reels. If you have a stainless steel reel verify that the retainer clip is centered in the reel and the film will lay flat across the rod the clip is on. Being the last 1 1/2 inch of 120 film is not exposed if the camera/film holder is working correctly I fold the outside edges even with each other then make a 1/4-3/8 crease down the center of the film at the end for an aid in centering the film in the clip. When winding I run the back side of a fingernail around the edge of each turn as I make them to ensure the film is winding correctly. Bends and buckles are caused by the film not being centered at the clip.

I messed with the barn a bit and could get the snow white

I am using the same software as my digital photos as I took pics of the negative with my macro and "inverted the curve" to turn it positive. If I scrunch the levels in and put somewhat of a bow in the curve I can get the snow pure white and still keep details. |

I am using a 2 reel - patterson tank and plastic reels for developing, I watched a couple of videos on loading onto a metal reel and that looks somewhat easier in full view.
I appreciate all the help you folks have been providing me as I learn. |

I looked at your photo in CS5.1. The blacks start at 13, the brightest end at 240 with a gamma of 1.02; adjusting gamma to 1.17 gives the best detail in the snow. Development is uneven, slight over on the left, slight under on the right 2/3 of the photo. This is due to your agitation technique and the chemical flow characteristic of the reel/tank you are using.

I am incredibly impressed at what you can diagnose!!!!
I watched a couple of videos where folks said to use the little spinner tube that goes inside the patterson tank and rotate the film reel inside the development tank as a way to get finer grain and more detail.
This was the first roll where I tried that technique instead of the gentle combination of rotate and inversion that I had been doing.
I guess it is back to the 1st technique I was using. |

Well, my diagnosis need a pinch of salt! What I/we are seeing is the histogram of your DSLR not the negative you are copying and the histogram may be in error. Reader beware.
