infrared and XP2 redux

I suppose I’m a little despondent about the digital IR results to date, but there again it’s early days. Seeing that the old Yashica will be fixed sometime in the near future, I wonder what results I’d get if I loaded it with XP2 and used the Hoya R72.

Thanks to Rob Novak for showing me why this idea won’t work…

XP2’s response drops greatly after 630nm, and has virtually no response to wavelengths below 660nm. The R72 filter’s transmittance curve doesn’t even start until 700nm, reaching peak transmittance at 750nm.

This one is doing strangely well (for me anyway) on Flickr. I uploaded it sort of as a joke because it’s so like a photo by a photographer I admire called Catherine Jamieson from Canada. Click on the image to go to Flickr and all will be revealed.

I suppose I’m a little despondent about the digital IR results to date, but there again it’s early days. Seeing that the old Yashica will be fixed sometime in the near future, I wonder what results I’d get if I loaded it with XP2 and used the Hoya R72. The Yashica also has the advantage of 28mm, 50mm and 70-210mm lenses. It will be interesting to see. I wonder if I can get into the grounds of the bowling event in Dun Laoghaire in September so that I don’t have to shoot through the fence. Although I suppose the fence gives credence to the perception of elitism around this sport in Ireland.

Hmm.

There’s always the bowling green in Herbert Park. I need some good light.

Here’s the first IR shot I’m relatively pleased with. I’m finding it difficult to get the shots in focus, perhaps because of the long exposures involved. This one is no exception, but at least it’s relatively focused.

Exposure: 1 sec (1)
Aperture: f/4.9
Focal Length: 22.2 mm

I can’t remember what the ISO was but probably 50 or 100. It’s a shame that this info isn’t recorded (as far as I can work out) as part of the EXIF data. I must crank up the ISO to 400 and see if this helps with the exposure length and thus focus. I guess it’s a trade off between noise and focus.

ir idea

I’m wondering if it would be possible to paint a scene on a very long exposure using remotes like in Risky or Steve Winwood. Maybe a cluster of remotes all strapped together. The only radiation source being the ir from the remotes, natural or tungsten light sources eliminated. Have to wait for the equipment to arrive and a tripod to do the test.In the mean time, getting ready to shoot for a wedding. The groom is wearing tungsten rings for men and they look amazing with the ir view. The bride with her white gold engagement ring is a bit harder to capture correctly with this setup. I’ll update with more information when I have the time.

Here’s the first IR result. Got the Hoya R72 today. Handheld in front of the ixus – no mount or tripod.

I’ve been looking at flickr a lot lately and have come across some amazing infrared photgraphy which, until very recently, I didn’t realise was possible using a digital camera. I suppose I hadn’t thought about it too much, but I’ve decided to try for myself.

The first thing to check is to see whether or not my camera (Digital IXUS 500) is usable, and one way to do this is to point any remote control at the camera, press a button and see if the IR beam is visible. Happily for me, it is – see above.

The next thing to do is find an IR filter, and searching around the web, it seems that a Hoya R72 will do the trick. Seeing that I’d like to share this filter with my other cameras, a 52mm filter seems optimal.

Finally, I need some sort of device to attach it to the camera, and with the guidance of publicenergy on flickr, I ordered one of the adaptor tubes from hkdcplus.

So now I am in wait mode – both filter and adaptor & step up ring are in the post. The results will be posted here.
