A while back, I bought a few rolls of Ilford SFX 200 and shot it with a red filter. A normal red filter, as you would use for normal films. I likes the results and I decided that I wanted to take it one step further and try out the invisible spectrum. I bought a few rolls of Rollei INFRARED 400 and began looking into tips and ideas for dealing with infrared photography. I soon learned that what I thought to be infrared films were actually just normal films with an extended red-sensitivity and that it didn’t really go into the proper Infrared spectrum.
My first decision was that I wanted to try this out with my best equipment. I opted for my medium format cameras, the Bronica ETR and the Hasselblad 500c and bought a filter that would fit both of them. A relatively simple an straight forward 720nm filter off eBay, the brand is Greene or something along those lines and it seems to work very well. Although, no filter factor was provided, so for this round I only did two compositions and bracketed a lot to get to know the filter somewhat. From my experimenting, I found that the correct compensation for this filter is about six stops.

My first idea for this tryout was heading towards a little river passing not far from where I live. The area around the river was too overgrown for me to get any shots of at this point, so I decided to go for a forest scene for my first composition. The exposure time got into the multiple seconds, and the one I was most pleased with was the one at 4 seconds. It gave me the infrared effect that I was looking for.
I then moved on to look at the view over Gåstjernet, a little pond in the same area, and I noticed how nicely the clouds reflected in the water, framing the landscape very nicely within the 6×6 format. I think this became the stronger of the two compositions and I also did the same amount of bracketing on this.

My next problem was development. I wanted to use a relatively fine grain developer to get the most out of the effect, and the only one I had mixed was Ilford ID-11. However, there were no instructions on how to use this developer for this particular film so I had to get creative. I extrapolated the Xtol-time, comparing it to other Rollei films and ended up with a development time of nine and a half minutes. This gave me very nice negatives and the ID-11 seems to have worked very well with this emulsion.
