This was my first attempt shooting infrared in the Holga 120N, my lovely little plastic camera with the plastic lens. I’m going to admit that I totally messed this up by forgetting to change it to bulb mode so the resulting negatives were extremely thin. I had not received the R72 filter yet so went with the #25 red filter. I didn’t expect anything from them at all so I was surprised that we managed to get these resulting images.
In infrared photography, the film or image sensor used is sensitive to infrared light. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used (that would be the R72); this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). (“Infrared filter” may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.) Even though I did not have the perfect filter for the job you can still see the infrared effect.
When the right filter is used together with infrared-sensitive film very interesting “in camera effects” can be obtained; black and white images with a dreamlike or sometimes lurid appearance known as the “Wood Effect,” an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence but this is marginal and is not the real cause of the brightness seen in infrared photographs. Add to that the lovely vignetting (the blurring around the edges of the image) that the Holga plastic camera is famous for and you can get some really cool dream like images.
Although not true infrared quality, I was pleasantly surprised with the resulting images. I have since received the R72 filter and if the weather cooperates will be shooting some more of this Ilford SFX film.
This film was also developed in our favorite developer, Moersch Tanol.
