Medium Format Infrared Images

Cool, Ari! That's an interesting structure.

For my pictures above, I used a GW690II, Rollei Infrared 400, and a R72 filter. I've been bringing my film to a local lab for development, but I know they use D76 and that they went off of Rollei's box recommendations for time (11 minutes I think?). As far as metering, I rated the film at ASA 6 and that worked well. I scanned the negatives using an Epson 4990 flatbed which I can't believe is still going after all these years.

I hope all is well with you.

Thanks, Austin. And I hope all is well with you.
All your infrared images look great, and not just because of your lab, of course, but it helps that they use the proper developer and time.

As you can see, I'm still in my "moonscape" phase of shooting IR.
And I'm also using a 4990, I think they're un-killable!

Austin:

Beautiful work young man. I’m thinking of trying some Rollei 400 4x5 sheet film. At ASA 6, what filter factor did you use for the R72 when calculating your exposure?

Thanks, Jeff! I've been considering buying some of the Rollei IR in 4x5 as well. It's got my mind turning.
The rating of ASA 6 is with the R72 filter on, meaning I slapped the filter on, set my Pentax spot meter to ASA 6, and went with its recommendations. When I'm metering, I'm always thinking of zones, so I'll meter the area of shadow where I want to retain detail, or else the brightest highlight where I want to retain detail, or sometimes just an area that I imagine being middle zone V or whatever, and then I'll let the rest fall where it does. Ansel would be disappointed that I don't use development for further control, but "normal" developing usually works fine for I'm doing. Sorry Mr. Adams, I'm a bad student! Anyway, to return to the Rollei IR, basically, with the R72 filter in place, I pretended it was a 6 speed film, and it worked out fine!
