I went to 2 shops while in Vancouver (Home town) to check for an IR filter, a filter that Japanese stores just don't carry for some reason. After that I started to call stores rather than go and every store either didn't carry or said they could order one because it was a special goods item. Didn't realize this...
At the last store I checked the guy seemed to try and convince me that all the IR stuff could be done via PS. Can someone explain where it differs? And can someone point me to an online store that would ship to Japan now that I'm back here.

LOLOL! And he calls himself a salesman?
*ahem*... now that I've regained my composure, no, you certainly cannot truly replicate IR photography in PS, although it is possible to kinda replicate the look.

True IR photography relies on longer wavelengths of light than we can see. Faux IR relies on swapping red, green and blue channels around, among other tricks, to try to reproduce the look. Most efforts are extremely easy to spot.
Try here. They ship internationally. |

You might try ebay. A lot of them are available out of China and Hong Kong. PS cannot make true IR photos. The reason being that objects do not reflect visible light the same way they reflect Infrared. What the IR style conversions do in PS and other image editing program, is apply a red fitler, and then convert to black and white. In true IR photos, the sky is dark, the leaves on trees and plants are white, and the list goes on. If the object absorbs infrared it is dark, and the more it reflects infrared the lighter it is. An objects coloring in visible light does not determine how it reflects infrared.
I just checked ebay and there are several sellers who will ship to Japan. Keep in mind a couple of things. The R72 (720 nanometer filter) will allow a small amount of visible light through. The images are good for doing false color IR (see the current IR posting thread to check for examples) 950 nm leaves a slight greenish cast. 1000 nm is about pure b&W. If your camera is not natively capable of IR shots (ie. the sony nightshot capable cameras and some others), you will need to have the hot mirror in the camera removed and replaced with your choice of alternatives. My Canon 40D, with a 950 nm filter, is blind even at long exposures. The hot filter which is designed to block IR, does a really good job. |

The IR filters available in Japan are the square Tri Acetyl Cellulose type. Fujifilm makes them. Of course, you'll need a holder. I have one, but light does seep in from the sides if you're not careful (not sure how to light-proof it).
I once tried ordering a screw filter from US Amazon but they wouldn't ship overseas because it's glassware.
I was also mystified as to why the Japanese stores don't sell screw IR filters, considering that Hoya makes them.

I was looking for an IR filter so I figure I would just bump this thread rather than start a new one. I am looking for one for the Cokin filter system or one that will fit a 77 mm thread which I think is much more expensive. Is this Cokin filter I am lookng for? Cokin P 007 IR filter. I am just making sure as I make a Christmas list. :)

Joe, if you use the Cokin P series I have an IR filter I will send to you. I bought a 350D and had it converted and have no use for the filter so I can hook you up. Let me know! |

I do all my IR work with the Sony F707 with R72 filter and shoot in nightshot mode.
