So I got a little package in the mail today....

A Hoya 52mm R72 Infrared filter. I just had to play with it...

//www.dpchallenge.com/image.php?IMAGE_ID=21706

This is the best shot that I got just holding the filter in front of the lens. The adapter that will let me fix it to the lens should be here soon.... I can't wait!!

SWEET!!! I better get one for mine now. That looks like fun! Does it work on "warm bodies" at lowlight? ie: brings them out more? I have many little critters that run around in front of my house and want to "catch" em in the act. I haven't looked much into the infrared, so excuse the ignorance. (C:

turn on your camera. point a infrared remote control at it (almost all are) and se if you can see the little light in your lcd.

I've only just begun to play with the filter, but I don't think it's going to amplify warmth in bodies or heat sources. That is true infrared (i.e. night vision). This filter really just amplifies the light sources and surpresses the darks. At least that's the feel I get so far, but then I only got to play with it for about 30 minutes.

I messed around on google the other day doing searches for "infrared CoolPix 5700" and found this link:

//photofilter.net/shopsite_sc/store/html/index.html

I didn't have a chance to see if there were better prices out there. The sources seem to be pretty limited. But this guy turned my order around in two days for $3.00 (US) shipping.

I found the filter adapter kit (which will allow me to use the treading on the filter to mount it to my camera's lens) here:

//members.rogers.com/nextphoto/

I could spend alot of money with this guy on accessories for my 5700. I would think that there are others out there who make these sort of accessories for other models/brands. I'm waiting for the arrival of my order right now.

I chose the 52mm adapter so that I can use this infrared filter and some of the other Cokin filters that I have for my SLRs. The 52mm infrared is also the size for my best SLR lenses so I can play with film too.

Can't wait to play some more!!! I'm heading to Ft. Lauderdale in a couple of days and I'm definitely taking this stuff with me!!

Very cool. You really make me want to buy some filters and try out IR photography.

Great stuff. Nice shot. Some of my recent IR endeavors... //www.pbase.com/davenit/ir

Enjoy...

Dave N, do you have any advice for choosing an infrared filter for the 10D? And how did you get the blue sky in your infrared shots, some other filter or spot editing?

BTW, just to clarify the term infrared gets used to two different things. This is really near or short wave infrared (typically 0.9µm - 1.4µm) whereas images showing warm bodies in high contrast are thermal or long wave infrared (typically 8µm - 12µm). The latter is indeed one of the technologies used for night vision, but it's way expensive (glass is opaque to thermal energy, the lenses have to be made of germanium!)

Magnus, the 10D is no good for IR. The IIRC is way too strong. You end up getting exposures way too long with a 72 filter. I shoot all my IR stuff with a Canon Pro90 IS. Image stabilization helps a ton. Usually exposures from .5 to 1.5 seconds... I shoot both NIR (72 filter) and true IR (black 87 Wratten). The images I linked to are all shot with a 72 filter and then channel switched. Copy the red channel into the blue and the blue into the red. Simple technique but gives a real neat affect. I am just really starting to understand how heat reacts in my camera. Having tons of fun...
