فيلم إلفورد SFX 200 سلبي أبيض وأسود (فيلم ملفوف 35 مم، 36 صورة)

Finally got some really nice infrared effects using a deep red filter on this; the extended red sensitivity to 720nm makes a noticeable difference. The contrast came out beautifully even in overcast light.

Shot a roll of this with a red filter on my Pentax and the skies came out nearly black against the clouds — that extended red sensitivity to 720nm really does something you can't fake in editing. Grain is fine for a 200 speed film, and all 36 frames developed clean.

Loaded this in my rangefinder for a foggy morning walk and the way it pulled detail out of the haze surprised me. That 720nm red sensitivity gives skin and foliage a glow I just don't get from my usual 400-speed stock. Thirty-six frames went way too fast.
