I am planning ahead a trip to old fabrics factory. As I'll be chasing mainly people at work and their personal portraits I am looking for a film which would do well in dark environment. I had a thought to go straight with kodak portra 800, but as I have rather bad experiences using portra 160 in shadows then I started to wonder how good idea this actually is.

I have some kodak bw400cn as well in case I should want to go with bw. Ilford xp2 would be another option. I have to stay with c-41 line for fast turnaround in this project.

Thank you!
