experimenting with shutter speeds and f-stops. it's interesting to see the differences between f-stops... not so subtle in many cases. f/5.6 creates very grainy images, but also creates a somewhat haunting mood. f/16 is sharper, depending on the shutter speed. would like to try some of these images again with a true IR film, such as the efke 820.Taken by djimbee with a Canon AE-1 Program loaded with Ilford SFX 200 film in Portsmouth, NH, United States. These tags describe this photo: infrared and filter. This photo can also be found in the album canon ae-1 w/ ilford sfx & 720nm IR filter.
