Hi there,

I'm in need of some help with my dev times here.

I have some Rollei IR400 which I exposed through a Hoya R72 filter with the camera ISO set to 50.

I previously developed this in 1:2 Xtol for 18mins which worked pretty well, only I can't get my hands on Xtol this time - I only have Ilfosol S.

So can anyone tell me how long I should develop this in the Ilfosol for?
Or does anyone know how to calculate a Ilfosol dev time from an Xtol one?

The MassiveDevChart has a figure for Ilfosol + IR400 @ ISO400 but I'm not sure this would apply when I've exposed @ 50 with a R72... any ideas?
