Infrared Film

[smallfooties]

Hi all,
I have a roll of Rollei Infrared 400 film that i have been dying to use.
Has anybody used this before?
How should i use it? What should i be aware of? How to get the best results?
I was thinking of getting the Ilford SFX filter to use it with but when i did a search on fleabay, the results were the Ilford SFX film... Does this mean this film already has the filter effect on it? Or does it mean a totally different thing?
I think shooting foliage will be good on this film but am i totally losing track of myself?
Any tips will be good...
Thanks kindly.

Looks like nobody has used IR film before????
Or is everybody ignoring me??????? Sad....

Well you keep poking your tongue out at us...

There have been some recent posts here on IR, but I think overall it's a pretty narrow field of interest. If you haven't tried already maybe give the Flickr infrared group (http://www.flickr.com/groups/infrared/discuss/) a go.


Cheers.

hey phil!
Thanks for the reply!
because i have a relatively short tongue in reality, this avatar's tongue intigues me so i thought i'll show off 'my' tongue here!
hehehe....
Ok i will have a look at Flickr!
Thanks again!

Sorry smallfootsies, longtonguies
Not ignoring anyone
No experience with IR filum
The only thing I have noticed is to keep it in the dark
Don't open anything except in total darkness, including inside a heavy black bag.
I think the view finder has to be blacked out too, lens cap kept on till the last moment & put back on right away.
No, nill, nort stray light
Cheers

oh my goodness...
didn't know that IR film is so sensitive to light!
eh... i've kinda opened the canister the film is kept in, took it out to dream about when i could use it... for about 30s and put it back in it's rightful place!
I hope i have not ruined it!

I'd suggest a dark red filter, even a Wratten 89B (or equivalent).
Load and unload in subdued light.
With an IR filter, the ISO will be about 6. I'd suggest bracketing with a one=stop step
Work in sunlight.
Has your lens for an IR index (a small red dot on the focus ring) ? If not, use a small aperture, or rack the lens out slightly.
Treat it as an experiment, if you've never used IR film

Stan is (partly) right about the filter. As it is a B/W film, an 89B, or even deeper, 87B, is what you'll need to eliminate most of the visible light and expose using only the IR (and that's near IR, spectrum. I just posted this link in a thread to Colinbm. You can have it too.

About the film itself, I found this link. http://www.digitaltruth.com/products...i_infrared.php
I haven't gone deep into it to check out what ISO settings to use with each filter, though. The chart shows that it does have some IR sensitivity and they even recommend an R72 filter. If yo can't get any of those filters, even (and this is a stretch) a deep red R25 might help. With that one, at least, you might get an ISO rating of about 100-200, and you may not have to shift your focus too much. If yo do go for the IR filters, then for a f=50mm lens, set your "infinity" mark at 10 metres. Have a look at this thread too: http://www.ausphotography.net.au/for...fraRed-Finally

Can't think of anything else 4 now.
Am.
Actually, the very first sub-link on the film site says that you can rate it at ISO25 for IR, that'd be with and 89B or deeper filter.

omg... what have i unleashed...???? kekeke....
Thanks guys for the help!
I will look into the links and see if i've got one of those filters lying around... but i'm sure i've got the IR filter.
Thanks guys again for the help!
I'll be popping it into my canon a1 and exploring like Stan said but, i also want to be technical about this so i achieve the best results!

Hi
On the Rollei use a dark opaque filter not the 25, I shot a roll at the Botanic Gardens a couple of weeks ago, to lazy to take the tripod, Stan is right with the 6 maybe even 8, I change my film with just a jumper over the camera, make sure your wife is with you, or you will get strange looks, the colour infrared has to be complete darkness, B&W seems to handle a little bit of the light.

I don't really know that the SFX film is really infrared.

Whatever you do be patient, and use a tripod, and write down every setting of every image, that way you know where you have gone wrong, or where it went right.

Regards
David

What's happened so far?

[doigal]

You want the R72 filter which is designed for B+W IR. Its very sensitive to bright light and shouldn't be opened out in the sun, load it in the shade.

SFX isnt really a true IR film, its only semi sensitive to those wave lengths.

example from a couple of years back, exposure details etc on flickr.


Got wood? by doigal, on Flickr

[smallfooties]

I've been looking for my r72 filter! Just found it ... so hope to get down to using the IR film...
took me awhile to find it and discovered that my pet ferret had stashed it under my set of drawers!
How he managed to get hold of it is a mystery... but i suspect he took it one night when i left my rolls of film on the bedroom floor...
kekeke....

[smallfooties]

oh and can i process the film myself in my darkroom... or would it not work - i would have to go to a proper lab?

[doigal]

that picture i posted was developed myself using the normal b+w method.

[StanW]

Youcan process the film at home; there's no problems once you decide on your developer and the time. Go to digital truth for information.
