Thanks for the reply! I'm just shooting Fuji Superia X-tra 400. . .Walmart special. The scanning software says it will go to 9600, but it's a cheapo HP all-in-one, so that claim might be stretching things a bit.
Times ranged from 6 minutes up to around 15. I failed to document times, or even targets. On future shoots, I'll have a notebook with me. D'oh!
