Response to Uneven Negative Development

I had a similar problem some years ago when I was shooting 120 extensively and it seemed to be an agitation/developer level in the tank problem. I went through about 25 test rolls, developing and inspecting till I arrived at a satisfactory solution. I found that when using the recommended amount of developer, the developing tank was almost completely full and left little room for the solution to move. Vigourous (and I mean really vigorous!) agitation solved my problem. Another solution would be to put your empty reels into your tank and fill it up with water until the reels were just covered, but the level is not completely to the top of the tank. Measure this amount (it is sure to be less than the tank capacity) and use only this much developer when you develop. This insures that there is adequate mixing room for the solution in the tank. Hope this helps, ;^D)
