KS - makes sense. I had a feeling maybe the film might be slower than 100. I will try and rate it at 64 and then develop a little longer. This was very flat light. That would be about 2 stops.
Tom - gotcha. I know nothing about flash photography. Nothing. What you said makes sense though.
Steve - I appreciate what you are saying, but the negative is way under exposed. That adjustment for me would be giant.
Ran TMAX400 through and problem appears to be fixed. So must be something I was doing with the arista and other films I had tried lately. That is texture on stucco not grain above the brick. Thanks all.
