Rollei infrared recipe

[rogerzilla]

USe a Hoya R72 black filter and expose in full sun at 1/60 and f/8 (or 1/125 at f/5.6 etc), which is ISO 25. Quite handholdable. There's no point in using it if there isn't full sun, so you don't really need a tripod. Don't forget the focus shift unless you have an apochromatic lens.

Pre-soak for 5 mins to get rid of the anti-halation (it pours out black). Then develop for 6 minutes at 20 deg C in Rollei* D74 at 1:7, inverting twice every minute. If you dilute the developer further you'll almost certainly get huge grain and the stuff is tack-sharp at 1:7, so there's no point.

The results are great - at least as good as the old Kodak HIE. See the gallery for examples.


*the softpack isn't actually branded Rollei; I think it's made by Maco but it's generally sold as a Rollei product.

Interesting. I have the R72 filter and plan to use Efke's Aura. I found a lot of great examples, from multiple people, and they all said use a hand held meter at ISO 1 or 1.5, which usually comes out to 1 second at f/16 in full sun.

I tried the Rollei film at ISO 4 to begin with (I'd seen it recommended elsewhere) but the negs were too dense for scanning even though the control shot (unfiltered at ISO 400) suggested underdevelopment, if anything. I guessed it was around 3 stops overexposed, hence the ISO 25 recommendation.

I've used both the Rollei and the Efke with decent success using B+W 092 at 25 iso, for 1/15-1/60, with f/4 or f/5.6. I have used both D76 and Adox ATM 49. Not much accessible information out there, so it's nice to get some more techniques...thanks roger

D74

D74

*the softpack isn't actually branded Rollei; I think it's made by Maco but it's generally sold as a Rollei product.

D74 is the successor of AM74 (Amaloco photochemicals) sold under LP Supergrain and Rollei High Speed (RHS).
It's a new product made by a famous chemical factory and they succeeded to minimize the amount of Hydroquinon in it.

Under Rollei label: RHS-DC. A very modern type developer. I am just busy to test it out.

The Rollei IR-400(S) I use with the Heliopan RG715 on an E.I. of 12.
