Another (probably the last) photo from my trip up north last week. These are sand dunes in Ludington State Park, just north of Ludington, Michigan. The dunes are located between Lake Michigan and Hamlin Lake. This was taken looking east, with Lake Michigan to my back:

The image was made with Rollei IR 400 B&W film and a Hoya R72 IR filter. I have to say I was a little disappointed in that the film just did not deliver much IR effect. It was a couple of years out of date, though stored in the freezer, so maybe that had something to do with it.

I’ve commented on this film before in this post. While up north last week I decided to shoot out my stock of this film, more or less just to get rid of it. I used a #29 deep red filter for most work, hoping to tease out some IR effect, but it really just behaved more like a standard B&W film.

The Hoya R72 filter really made the azure sky of summer turn dark black, but otherwise did not coax out much on an IR response. Here is a comparison of two shots of the same scene, on taken with the #29 deep red filter and one with the R72:

This time round I stand developed the film in HC-110. I rated some rolls at ISO 800 and some at ISO 400. The ISO 800 rolls I stand processed in HC-110, diluted to 1:100, for 75 minutes. The ISO 400 rolls were stand processed for 60 minutes. I experimented with more dilute solutions, but the double roll Paterson style tanks I was using have a maximum capacity of just over 650ml of water, and the solution could not get much more dilute than 1:100 with falling below the minimum amount of HC110 syrup needed per roll (6 ml). (Though they were double roll tanks only one roll was developed at a time with 650ml of solution.) The one time I did try a higher dilution I used only 4ml of HC110 concentrate, and the negatives were thin.

These shots were taken with a tripod mounted Pentax LX and FA 28-105 f4 - 5.6 power zoom lens (an older AF lens model.) I avoid newer film bodies (Mz-S, *ist) with IR film since they are reported to fog IR film.
