Development time help

[dave_osborne]

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?

Yes, this should be OK.

To check your development it's always wise to expose a frame without a filter and the normal E.I. I.R. photography is not always easy.

 

Best regards,

Thanks Robert.

Yes indeed I just tried Ilfosol S 1+9 for 7.25 mins and it looked to work a dream.

Thanks for your help.

Dave.

If you need some more development info for the Rollei films:

Take care with the storage of the Ilfosol S. It can not be stocked for a long time due to the ascorbic acid in it. Use it up within two months after opening.

The same with Xtol in a time limit of 4-6 months depending how you store the stock solution.

 

Best regards,
