The problem here is I use Delta 100, & HP5, often at the same time but different formats, and prints match.
I have 3 prints in a current exhibition set, and you would assume they were made the same day. In fact, although they are at the same location, Wheal Jane, near St Agnes, they different years (12 between first and last), and times of day, and different films/formats. Tmax100 - 5x4, Delta 100 - 120, and HP5 - 5x4.
Yes, I could use FP4 I just prefer Delta 100 & 400 for 120, so use it for 5x4 as well. HP5, usually for handheld LF work, but I have grown to like it for 5x4, but I prefer Delta 400 when I need a faster film for 120.
Much of it is down to nailing a film's effective EI & development time, and then printing skills.
