Many thanks to the input to this thread, everyone. I feel very hopeful now. I will push process the roll 1 stop and see how it comes out. I kept on forgetting to check my camera's ISO setting. I believe I had a roll of 160NC shot at ISO 320 before. I did not push it and it came out much too thin in density. The images were grainy. This time it is a 160VC. I am not going to take chances. I will push it 1 stop this time.
