IR photography for RFs?

[Fudgecakes]

Hi all senior shifus and uncles. Just wondering does anyone here still do IR photography on film? I realized that ruby was selling ilford infrared films and I was wondering If anyone had tried them out? Also, what kind of processes and chemicals must I use to develop IR film? Lastly, where can I find the illusive IR black filters? The usual haunts at funan don't seem to carry them. :dunno:

The ilford SFX is black and white film. You can process it with BW film developers. As for filters, IR 720 is a good start. You can get from seng cheong.

Oh thanks! I also heard of the efke IR film. Ever used it? Quite interested in trying That out too

The IR720 filter is from which brand?

Thanks a lot for your help sempai xP

I shot quite a few rolls of IR film before.. all IR films develop the same as normal BW films.. You need to check on the massive dev chart for development timings. You will need the R72 filter like sweat100 said.. but be prepared to pay top dollar for it.. recently the prices has gone through the roof. I got mine from Japan, Kenko R72 with multi coating. So far those I've seen in SG are Hoya R72 non coated and B+W. You may want to check with cathay? You will need to take note of the filter factor and the focus point shift (usually depicted as a red dot on the focus marking). Films also have to loaded in shaded areas as the film is very sensitive to light, especially the Efke IR820 Aura. RF is perfect for IR because you can frame your pic via the viewfinder as per normal unlike SLRs..

Oh. I've already checked with Cathay. They don't have it at that time. Sigh. Most of my Lenses are Leica. So no red dot. Any idea how else I can maybe 'estimate'?

How much did you actually pay for your filter? Have a feeling I wont be able to swallow the number lol. XP

You may want to check the spec sheet.

Very deep red
ILFORD SFX, B+W RG665, B+W 092, Heliopan 695
and 715, Hoya R72 and Kodak Wratten 89B. These
filters give an even more dramatic effect than deep red
filters. However, exposure times with these filters can be
very long, so the use of a tripod is recommended.

If you want IR Filter, go and check out TK Foto.
The price of IR filter increase exponentially with the filter size.

I paid slightly under $300. But mine is a 77mm and multi coated and I use step down rings to attach it to the various lenses I need, so I think its still reasonable. Cheaper to buy 1 big one then use for all lenses than to buy multiple exact sizes. If you use leica lenses, then 52mm should be big enough. TK photo or Ruby also sells, but those are probably the non-coated versions. The alternative is to get a square filter holder and buy IR gelatine filters (made by Fujifilm). Those are $10 a piece, but you can only find them in Japan.

If your lenses don't have IR focus dot, then just use apertures smaller than f11 (might be hard because effective film speed after filter factor can fall down ISO 6 for Efke 820 and ISO 12 for SFX200) and turn the focus ring a touch (1-2mm) towards infinity after getting a correct focus.

Ohh. I'll probably get the 49mm. It fits all
My lenses xP

Thanks for your advice!

I bought generic 720nm IR filter from ebay, i think cost lest than S$20, and it works. Filter factor 4-5 stops.

Rollei IR400S, HC-110 dilution H, 22 mins at 20 celcius, agitation every 1 min for first 15 mins, and every 30s for last 7 mins

 

[oceanpriest]

Rollei Infrared 400 35mm x 30,5m

36.97 euro for 100 feet (16 rolls), that's 4-5 rolls of Ilford SFX

I've done some on my M8 in the past, using R72 filter. I prefer using digital for IR as I have the ability to control the processing. I also like false colour IR which I find more interesting. Some lenses are also very prone to hotspots like the CV15mm which is quite annoying,as I had to shoot at f4.5 to avoid the problem making focusing even harder.

As someone e mentioned, RF is the best tool for this. Bring a tripod.

These were done using various lenses and Hoya R72.

Cool pictures bro! Thanks for sharing!

Something I noticed that I thought I'd mention; hotspots is a digital-only occurrence. Not a concern on IR film

Never knew that, thanks! Certainly very annoying to correct in Lightroom.

Cool info. Thanks! Any idea why that happens? Why only digital. cameras are vulnerable?

I think you can find some answer here.
