And IR film needs special care ;) For now, I'll stick with faking it.. until, of course, I get that RM-72 filter I've been wanting, which is still fake, but closer to the real deal :P Thanks for the link! Kim

Not at all, it is the real deal:)....if your talking about getting a filter for your digital camera.

Think of the DC sensor as having built in IR film. They can see quite far into IR and UV part of the light spectrum.

All the filter is doing is cutting out all or most,(depending on the filter), of the boring visible light so the good stuff, (IR or UV), can be collected for the image.:)

i'd like to try this when i find some time... thank you kim & mike for the links :]

Oooh, so the filters aren't cheating :D Great for me, but I have heard that some of the DSLRs have been built to block out most of the IR rays, so those people might still have to settle for creating the effect by postwork. Thanks for the info Mike =) Kim

Film/Digital I dont think it really matters if you achieve the effect that you want. Shooting ir film is at best difficult and a big waste of money if you get it wrong. If you are happy to "cheat" and use Photoshop etc, then why not go a ahead and do it. LP

Yep...I too would like to experiment with this....huggles

I dont think it really matters if you achieve the effect that you want Well....How do you know what you want? If you havent shot IR images before then your not going to know how the IR light reacts with materials. Alot of manmade materials absorb IR. All vegetation reflects IR, except for bark(it absorbs). Water turns into a mirror, glass turns dark. Certain clothing materials pass IR, the large leaf in the pic i posted above was close to death...notice how the IR passes through it, but then reflects off the live leaf below it.(All three leaves are laying in water, which i know will give me a nice black background at that close range.) Focal point of IR light is very different, it cuts through haze yet absorbed by smoke. Color IR is also possible...That RM-72 is the lightest IR filter. Meaning some visible light is also going to get in there and add false colors with the IR. I wanted the RM-72 one originally but bought a B+W 093..100$ :(....cuts 100% of visible light. My mistake...so i made 2 RM-72s with some polarized sunglass lenses, Gives me the false colors i want without the need for postwork. As for DSLRs, he explains that about those on that link i posted...In digital cameras, a tiny filter is infront of the sensor that absorbs IR so you wont have contamination in your photos. But they differ in strength depending on the camera. My Nikon 4300 loves IR. On DSLRs, it depends on the lenses you buy for it. Sorry for all the posts. I just saw Kim was interested in IR and was planning to buy a filter and i just wanted to help her on her journey into a different part of the spectrum. Mike

"Well....How do you know what you want? If you havent shot IR images before then youre not going to know how the IR light reacts with materials." I know and am sure that most people know what effect they want to achieve. I have shot ir, but my point was not specifically aimed at any particular person nor was it meant to discourage anyone from trying it. The fact is that not everyone has the camera that can achieve it, there fore by using PS etc a similar effect can be achieved, if by that people feel like they would like to do it for real they can then decide weather or not they want to go down that route. LP

This is interesting, thanks for sharing! TMG

Quick test for digital camera IR sensitivity:
Take a digital pic of someone with a TV remote. If the camera can see the LED on the remote light up, then it can pick up IR. Whether or not one can find actual IR filters for that camera is a whole other issue.

Thanks for reminding us of this excellent often over-looked Photoshop function :)
