> About the closest thing I had to failure was when I ran some tmax 100 for the first time using Kodaks reccomended time and ended up with extremely thin negatives.(posted 8418 days ago)that qualifies as a failure to me. anytime unexpected results occur, the process should be questioned. the additional observation that processing times are considerably longer that Kodak's expectations should be a indicator of potential problems. through experimentation, I have always had to increase times by 30% to approach useable negatives. I have often wondered about this.
