  Q. IR-images in PS?
Annemette Rosenborg Eriksen
Asked by Annemette Rosenborg Eriksen    (K=55244) on 2/5/2007 
Iīm very eager to learn how to make Infra Red photos. Unfortunately I donīt have a camera where I can mount a filter or use a film for IR-images. Is there a good way to make such images in PS?
Hopeful wishes:-)
Annemette

No. You might be able to FAKE something, but you're not going to get PS to turn a visible light photograph into something that looks identical to a photograph taken of the same scene in infrared.

You could get a filter and hold it in front of the lens.
When I use my little compact camera, I just hold/press a cokin 007 filter over the lens.

THank you, Sally! I must try that because Iīm quite fascinated my IR-images.
Best wishes

Hi Jeroen
Well Iīve heard that this should be possible. Iīm aware that it canīt get as good as when using the right film and filter, but itīs better than nothing.
Best wishes
Annemette

It's not possible. Quite simply put: if the data isn't there there's no way to make it visible.

If your camera doesn't record infrared, you're not going to get it.
Filters won't help either if you camera can't record it as all they do is suppress (most of) the visible spectrum so the IR data doesn't get completely blown out by the far more intense visible light.

Of course there are software packages that makes wild claims.
I've seen many of them. I've also seen claims by some filter manufacturers in the past that said that you only had to add their filter to your lens and you could photograph through clothes, effectively making nude shots of people without them getting undressed (ideal for voyeur kids watching girl sports teams hoping some skirt blows up and papparazi who can't catch their favourite celebreties in the shower).

Annemette -- There are a number of infrared plug-in emulators for PS. I have no experience with them and of course they only emulate and are not true IR.
Take a quick look at http://www.adobe.com/products/plugins/photoshop/
This page mentions a number of them.
However, I would make sure they have demo downloads before you buy anything so you can try them first. It would be better if someone has tried one and can actually attest to how well they work.
--Best to you, Jan

Thanks for your explanation, Jeroen. This means that my old SRL with a filter and a certain film for IR-photos must be the best option.
Best wishes

Dear Jan
Iīm very grateful for your suggestion that Iīll take a look at. Iīm feeling at bit divided now because I can see now that Iīll have the best photos if purchasing the right equipment for my old analog SRL, but on the other hand Iīd rather wait and buy this when I can afford a digital SRL, so photoshos plugins may be the best thing to do right now after all.
Funny what Jeroen wrote about people thinking that they could actually photograph other people as were they naked. There was probably sold much software at that time *LOL*
Thanks for the advice
Annemette

Ironically, there was a Sony video camera briefly on the market that had a special mode for low light conditions that did see through cotton and certain other materials. The camera was withdrawn quickly after the discovery of the X-RAY like effect. As Jeroen says there is a lot of hokey stuff out there that people think can really work.
I wish I could say that I had seen the results of these plug-ins but have absolutely no experience with them.
Good luck and have fun!!!
--Jan

To fake IR in photoshop check the following link.

Good luck.





 Jeroen Wenting  Donor  (K=25317) - Comment Date 2/10/2007
that camera had an IR filter that was broken, causing near IR radiation to be recorded as if it were visible light.
This can mean you can see a ghost image of a body through light clothing, but no more.
Unscrupulous people cashed in on that with "services" and "products" that they said would have you see through clothing like it wasn't there, enabling you to create actual nude images by photographing or filming fully clothed people.
Slight difference :)

Thank you very much, Derk! Iīll have a go at that one and see how it turns out;-)

Aha Jeroen
Well that actually sounds interesting being able to make ghostliking images although it was due to a broken filter. Sometimes itīs the mistakes that bring forth progress or new methods:)

Annemette,,,,,Nik colorEFX Pro plugins for PS can emulate the IR pic reasonably well along with that some use of the channel mixer and I have had some very good results

Oh really? I tried faking IR in PS, but I didnīt do well the first time, so Iīll try some more times and then maybe get such a plugin before buying a real filter and film. Itīs good getting so many responses giving me a sense of the possibilities for IR-images.
Thank you very much, Dave:-)
