I use EI of 6
mitch
I ordered five rolls yesterday and I will be sure to look inside the boxes.
Sirius, so did you initially try the Rollei times on the box and then found the result to be welding glasses density as mentioned in # 12? If not what decided you to use the times that are much closer to what everyone here uses, except Svenedin. The difference between Xtol times on the Rollei box and the rest of the times for almost all other developers except for Tanol is massive - head-scratchingly different to put it mildlyJobo processor, prewash replenished XTOL
68° F 7.5 minutes
72° F 6.0 minutes
73° F 5.75 minutes
74° F 5.5 minutes
75° F 5.25 minutes
17 minutes in Xtol seems a road to welding glasses dense negs. I want to run a batch using my Jobo but this seems insane, anyone else have some up to date beta on this?

It's a pity that Svenedin hasn't visited since Jan 2020 as pictures of his negs and prints would be helpful
Thanks

It may be that Svenedin is talking about the 17 mins time for Rollei at 400 i.e. without any filters but in that post he mentions using EI 25 with a R72 so it would look as if he sticks to 17 mins.Possibly, but it's for Xtol 1+1 at box speed. At EI 6, it would be much shorter, like 7:30. Still waiting for Xtol to show up on those shelves!
A slightly more nuanced response might be useful.For properly exposed film the development time is invariant to filtering.
Thanks Sirius. Can you recall what decided you against the long times quoted by Svenedin and taken from his Rollei box? Was it just a gut instinct that an increase in time of more than 200% to 17 mins just had to be wrong?I used the Digital Truth XTOL 1:1 times for Jobo replenished XTOL times. When I cannot find times for rotary replenished XTOL, I use the Digital Truth XTOL 1:1 times as a starting place.

If you are seeking Wood effect, and using a near IR sensitive film in conjunction with an R72 filter, you probably want to adjust contrast to what you want.
So I would take Sirius' recommendations for development times as incorporating the filter used, the resulting light actually exposing the film, and his judgment about resulting contrast.
If he were exposing the film without that filter, he would be working mostly with visible (not IR and near IR) light, and the contrast would be different, so I'm sure he would have given different development recommendations.
I know this is an old thread but I figured I would toss in my two cents. I shot my first roll of Rollei IR with a Hoya R72 recently and I exposed for EI 6 or 12 depending on the scene, and I extrapolated ~12 mins in Xtol (replenish) from the 17 mins in Xtol 1+1 listed inside the box (also listed on the data sheet). The negatives I got out of the soup were indeed "welding glasses dense negs." So dense that it was very easy to see the positive image by the reflection off the emulsion. Thankfully I was able to pull everything way down in software to have mostly usable scans and they actually look alright, albeit will all the sliders at the minimum value. Some were usable, some were not (see the attached examples). I haven't had a chance to print these negatives yet but I expect similar results.
I have another roll I plan on shooting and I am going to try the 7.5 to 8 mins mentioned here. I really wonder if the "1+1" on the inside of the box is a typo and they meant to say "1+2". Extrapolating 17 mins in 1+2 to stock solution is about 7.5-8.5 mins so that would make a lot more sense to me. I'll update the thread when I develop that roll for posterity.
