Current reciprocity champion in 4x5 sheet film

[TheFlyingCamera]

What's the current reigning champion of 4x5 sheet film for low reciprocity? Tmax 100, Delta 100? I know in theory Acros II is the champ, but if they make it in 4x5 you can't get it here in the US. I want to do some pinhole with the human figure, so I'm looking for something that isn't going to run into the tens of minutes for exposure in daylight.

It would be between TMX and D100, with TMX having a slight edge... I'd put my money in D100. Cheaper up here to begin with, and for "other" reasons that I will not get into I wish we could still get Acros in 4x5...

• 10-Second Metered Exposure:
  • Delta 100
    : Needs approximately 12–18 seconds.
  • T-Max 100
    : Needs approximately 11–15 seconds.
• 60-Second Metered Exposure:
  • Delta 100
    : Needs approximately 80–174 seconds (varies by source/chart).
  • T-Max 100
    : Needs approximately 90–120 seconds.

If you shoot color, Provia, which is still available in 4x5, requires no compensation for exposures up to 2 minutes.

While this is in the B&W serction, I think this is worth pointing out. A lot of people don't realize that Provia is essentially the Acros for color.

Even though I will never shoot Provia, that's good to know!

I did not know that. That's interesting.

Never say never Andy. You never know. I will say I probably won't shoot it either, but it's nice to know about its not needing any compensation for up to two minutes.

Why not try Ilford HP5. It's faster and you could probably push it a stop (time). I've used it for 4x5 for pinhole usually contact prints in pt/pd. All three on HP5 developed in Id11. Incident readings from Gossen Ultra Pro with the pinhole times from a dial calculator.

Nice squid. That was my junior high dissection project.

Anybody ever try to make a sheet of (almost) 4x5 Acros by taping two 120's together?

They were bait for a fishing trip.
