    Hey, I'm on my way up to the camera store, in search of Ilford's SFX 200 film. Has anyone used it? Is there anything I need to know about it? I plan on using a Vivitar 25A red filter that I have.

    Thanks!

    nopers, is that IR film..
    I have a few rolls of Rollei IR 400 to shoot, but I gotta read up on actually how to shoot it, I dunno what speed to shoot it at, I do know infra red light focuses at a different distance to normal daylight, you have to take that into account when focusing.
    So in summary.....I know bugger all, but I'll be inerested to read about your exploits with SFX..

    It's not IR film, but it has an "extended red sensitivity". It is suggested you shoot it with a deep red filter to achieve near infrared pictures. I'm curious as to what will happen with the 25A filter, I'm guessing a somewhat 'half' infrared-like picture -- if you will. I'm wondering if development will be the same, etc.

    I did read that Kodak's IR film is supposed to be loaded in complete darkness or subdued light -- one of the two, can't remember. I figured it would be good to know if Ilford's SFX needed the same. I'll probably load it in subdued light anyway.

    Well see how this goes :p

    SFX is great stuff. Peak sensitivity is at 720nm and extends up to 740nm. It's very easy to shoot with a #25 or #29. It can also be shot with an 89B, though it will get really really contrasty since the IR part doesn't extend into the 800nm+ range. It tends to be pretty grainy, but really lovely stuff overall. It can be loaded in subdued light instead of complete darkness like all the other IR films that are currently made except for Fotokemika/Rollei/Maco/Efke/Adox Near-IR.

    Here's a shot on SFX shot with a #25 at ISO 200, developed in TMAX developer. As you can see, IR tends to have somewhat of a see-through effect on certain clothing, especially thin stuff. Shooting films with greater IR spectral sensitivity will increase this effect.

    Awesome, thanks for the help, Max. I'm on my way now to pick up a roll or two. I'll be shooting with the 25A unless they have a REALLY cheap deep red filter. I'll be sure to post results!

    I shot sort of an "experimental" roll with it a couple weekends ago. The contact sheet looks great, but I haven't gotten around to enlarging anything yet. Looks like it has really nice contrast.

    So the camera store down the street figures they shouldn't carry it. D:< I'll have to order it online. I'll order a few rolls tomorrow and hopefully they'll come by next weekend. For now, I've got more rolls of TMZ P3200 than I can even know what to do with, so I'll have fun with those for the weekend.

    I'm really bummed they didn't have it. Oh well.

    frXnz, have you scanned the contact sheet? I'd love to see how it came out.

    I haven't scanned the contact sheet. Perhaps I will tomorrow, if I finally get around to hooking up my scanner ;)

    Here it is. Most of the images are overexposed (I meant to stop down a step, I did it backwards ;)), but hopefully you can get some idea.

    EDIT: I have another half contact sheet somewhere from the same roll, which might have some more (properly exposed) photos on it. I'll see if I can track it down.

    Wow, that stuff is really cool. I'm gonna order a bunch of it tonight. What kind of filter did you use, frXnz?

    I used a B+W 090 red filter, which is like a #25 if I recall correctly. I kind of wish I'd gone a bit darker for the foliage stuff, but it works nice one stuff where I'm not looking for a real distinct infrared look.
