looking for an ir filter

[back alley]

my local camera store seemed to have lots of the ilford sfx film.

maybe it's just the last of theirs, dunno.

Just verified that Ilford SFX 200 is definitely discontinued:

I would strongly recommend the new rollei 400, it quite something, and comes in 120 size as well.

locally there is the maco. i'll have to check and see if others are being stocked also.

Today, I went out and shot two rolls of the Rollei IR400. I had a Hoya R72 filter on (everything below 720nm is blocked . . .. I must have very deep sensitivity in my eyes because I can see through it and it looks sweet). Shot at +8 stops and +6 stops with 1 or 2 stop bracketing at F/16, 22, and 32.

We'll see how it looks - I'll be posting the results tonight - on this thread, I guess for a look at the Hoya R72 on a film very similar to the Maco*.

I don't think it is the same - developing times are given as different - but I don't know.

Okay

Okay

Here are three shots on the Rollei IR400 with a Hoya R72 and +6 or +8 stops of compensation for the filter factor. I noticed that +6 generally did it pretty well. It was very sunny this afternoon, and I shot these when the sun was just about to go behind the trees (still pretty high in the sky) - maybe 5 or 6pm.

Developed as a 400ISO film in Arista Premium Developer (Clayton F76+) for 7 minutes, 68 degrees F, gentle agitation every minute, 1+9 dilution. No stop bath.

THe middle shot was AT the sun, the one of the street was with the sun to the right, and the one with the barbed wire was with the sun to my back.

Due to pressure from APUG members Ilford are making a run of SFX in July. 35mm only. See this thread on APUG.

The Rollei 400 gives sharp fine detailed negs but really needs stronger filtration than the wratten 29 I used here

I also found that the rollei 400 make a pretty decent "regular" b&w film. That probably means that you can filter in a variety of ways for different effects, or even do a composite of an IR/visible shot.

Anyone here ever look through one of those opaque filters? If I look through my Hoya R72, I get the IR effect. Certain plants are white and the sky is really dark. Maybe I have extended IR sensitivity in my own eyes. . .
