Ilford SFX200

In 2013 Ye Olde Photographer obtained some Ilford SFX200 film, more correctly described as "extended red" than infrared. We ran a series of shots at a favorite test site trying an assortment of filters. What you see here are negative scans done on YOP's Epson 3200 with a minimum of tweaking.

For this we used the Yashica Mat 124G TLR which conveniently avoids trying to look through the filters to focus and compose. This was on a summer afternoon in July around 3:00 pm with a hint of haze due to high humidity, but generally sunny conditions. We shot with each filter at box speed and about a half to one stop additional exposure, using a Sekonic L-508 in incident mode for readings. A broader bracket was used with the IR filter.

For this, Kodak HC110 developer, dilution E (1+47), was the soup of choice. About 13:30 developing time at 69ºF (20.5ºC), agitating three inversions every thirty minutes for 13:30 (the first 30 seconds used constant inversions with thumping to dislodge bubbles). YOP was pretty pleased with the overall results. In general the film seems quite nice, although the premium price might rule it out unless one needs its special characteristics. It is interesting that there is noticeable "Wood effect" with the Wratten 89B filter in spite of the film barely reaching the infrared region in its spectral sensitivity.
