Hey, I just heard the guys at Hoya are really upset with you at the moment. ;)

Sounds great, can't wait to get home tonight to try it.
I was all set on buying an expensive IR filter and it turns out that not all digital cameras can capture IR photos as I think some have special IR cut filters to limit IR contamination artifacts - or at least that's what I've read.
I believe my camera (Olympus C-8080) cuts out nearly all of the IR spectrum.
So this could be a great solution - YAY!

Ha ha. Well, it's not perfect. I'm sure the correct IR filter works better but it's fun to try out.
I would still like a filter as you can take pictures at night using an infra red filter over the flash. You don't see the flash fire because of the dark filter but you do get a visible photo.

Yeah, you should probably select bright (formerly green) foliage, paste it into a new layer, and apply a moderate gaussian blur. That might approximate the surreal effect you get with true infrared.

There's always the DIY filter route - my camera seems fairly responsive to IR (I can even use my TV remote as a flashlight).
If you stack a couple of black frames snipped from processed color negatives, it turns out to be fairly opaque to visible light but transparent to IR. Relatively long exposures in full sunlight with this DIY filter in place turns out some interesting results. I need to screw around with this some more, but here're a couple of samples:

There's lots of good information on infrared photography and the Woods effect here.
Sometimes I need to pull down the constant in the channel mixer to keep hotspots from blowing out too badly.

Can someone with a true IR filter take a shot with the filter, then without the filter (+photoshop) and post the two shots? If the photos look the same I'll try the technique. If not, I'll buy a good IR filter. ;)

None of this is a substitute for having IR-sensitive film and filtering out visible light and capturing light that is wholly outside of the normal range/color of light you normally see, I'd like to note.
Some digital cameras /are/ sensitive to IR. Homework: Point your digital camera at your television remote control's end and press its button.

Glad to see people's attempts came out well. mariarenee is right that the result really depends on your original colour image. I think having a good mix of colours with blues, reds, greens, yellows etc helps to get a nice variety of tones.

Another DIY method is using Floppy Media. Rip open a floppy, take out the round metal disk and stick that to an extra lens protector or just hold it in front of the lens.
It's not fake IR, but poor-man's IR.
Some examples:
The top are from the 3 1/4 inch floppies and the bottom one is from 5 inch ones. Guess the smaller ones are better. The 5 inch media is too thick and the camera has problems focussing through it.
And yeah, all this was shot in Night Mode (Sony Digicam). Then converted to black and white.

from what I've read elsewhere it's good to shoot for an overall percentage (in the channel mixer) of 100.
Faux IR stuff I've seen suggests.
Red -80
Green +200
Blue -20
Another method uses layers. Channel mixer and levels adjustment (auto per chanel enhancement) layers on top of a blured+duplicate screen layer (25% opacity) to dial in the glow effect.
Then you go into the levels layer and adjust the ouput highlights so they don't clip (use real histogram not levels one) and lower the gamma to approx -1.34 ish.
it's fun to tweak anyway...thanks for the topic

I've had some interesting success with 100% green, 0% red, 0% blue. This comes from back when I was shooting real IR and green was the least-noisy and most details of all the channels, and I stumbled against that looking good for non-IR quite by accident. I may have to experience with subtracting a bit as well as this thread tended to suggest.
0% R, 100% G, 0% B. Anyhow, being able to have a bit of fun without a tripod is worth it sometimes.
The floppy trick looks pretty interesting -- I'll have to try it! Thanks!

Y'know what, try as i might, i just can not get it to look decent... I've tried monochrome, i've tried changing only the color slider for that channel that's selected in the channel mixer, and i've tried only changing the channel sliders in the red channel... nothing... what am i doing wrong here?

I know what you mean re getting it to look decent - You might consider the photos you are IRing. As with "real" infra filters, I think the composition, color and depth of field with the orignal subject are crucial. I find the effect is more dramatic on very vivid, nature and extreme depth shots. Thanks for posting this technique, though, I've been goofing around trying to arrive at this end result with slightly less satisfactory results, you've taken a much shorter, easier route than I was trying.

okay, so here's the question... when you pull up the channel mixer... there's the dropdown box that gives you Red, Blue, and Green... each one of those has the RGB sliders in it... I'm not too familiar with the ins and outs of the more advanced color features in PS, so I'm not sure if you'd go dropdown to Red, alter only the red, leave the other two zero'd, dropdown to Green, alter the green slider, zero the other two, etc etc, or if you'd alter all the sliders to the percentages identically in each dropdown channel, or alter the sliders in just one color channel... i'm utterly confuzzled. nothing looked decent lol

tf5 bassist: You leave the drop down menu as default to red. The sliders are just below 'source channels' where you have red, green & blue and monochrome tick box. Maybe you have photoshop elements or a different version of photoshop, I use 7 currently.

GlenC and Shiro Hagen's blur addition is pretty key, in my opinion: IR shots I've seen in the past always have a pretty surreal glow going on in them.
I don't have any "true IR" simulations to share, but fiddling with the techniques of this thread led me to this image:

tf5_bassist...you need to set it to monochrome (check box)...this changes the drop-down to gray. Once that is done, you can dial in the 100% mixuture.

This is my best attempt. After you get the basic pic, I think it needs a haze or slightly softer focus.

Here is an attempt.
I went back and read the blur layer method (for the glow) and it mentions that you need blur only the green channel of your duplicate layer. (Implying that you should only blur your enhanced channel). Once you do your blur, use edit-fade-25% opacity-mode = screen.

I'm not a huge fan of IR or IR-effect photos, but I decided to have a go at it anyway with f8125's method, plus a little added bit of my own to produce the "surreal glow" of IR photos:
1. After you've used the channel mixer as f8125 describes to convert to b&w, select all (ctrl+a), copy merged (shift+ctrl+c), and paste (ctrl+v).
2. Set the blending mode on the new layer to "lighten". Then with your background color set to white, Filter/Distort/Diffuse Glow. I used the settings 1, 7, and 10.
The result is something like this:
I'm not a big fan of the effect (and perhaps not the best image to use as an example), but I think this gets slightly closer to the look of an IR photo.

Applied the fake IR method, but I had to skip the last step to convert to monochrome -- I liked the colors too much. I further enhanced the colors by:
1) Changing the mode to Lab (Image->Mode->Lab Color)
2) Balancing the levels on brightness channel (ctl-1) and ctl-L; adjust accordingly.
3) converting back to RGB on the main channel (ctl-~)
It has that early western color-film look.

TLA8:
1) Upload the image to your flickr account
2) Click "All Sizes" (the link appears above the image)
3) Choose Small or Medium (again this appears above the image)
4) Scroll down and look for: Copy and paste this HTML into your webpage...
5) Click inside the box, copy to your clipboard (ctrl-c)
6) Compose your message and paste the html (ctrl-v)
Preview and post -- voila.

Thanks "f8125", good idea for infrared. I created an "action" so I could do a short cut when I want to do this in the future. yeah, I already bought the $100+ Tiffen 87 filter! LOL!! Oh well, it has been sitting on my desk for months. gotta try it out soon . . .

well heres an attempt at f8125s original method
Before Faux-IR
After Faux-IR
Colour Faux-IR
and by GlenCs estimates
B/W
Colour
i used
image>adjustments>hue/saturation
saturation = -100
for the black and whites
i love the B/W of f8125s method i think it improved the picture, overall.
i love the diffrences between the two colour examples.
i think this has bought a little more life to what could have a been a slightly uninspired photo in my collection.
i've found these results quite exciting and i cant wait to get out try it some more.

I've tried all the above advice, and tried a couple of downloaded actions as well, but none of these seem to create that very dark sky, and almost white foliage so typical of film IR. I have fiddled away with constants and channel mixer with no avail.
Anybody got any ideas for that look?

Here is my faux infrared photograph, but I used a slightly different technique:
1.) Start with a RGB color image.
2.) Go to image and verify that your Mode is set to 16 bits.
3.) Make a copy of your BG layer (control or command J).
4.) Add a levels adjustment layer (e.g. Layer > New Adjustment Layer > Levels). When the dialog box appears, simply click on Options and check the second box from the top, Enhance per Channel Contrast. This will increase the levels in every single channel.
5.) Add a Channel mixer adjustment layer (e.g. Layer > New Adjustment Layer > Channel Mixer). When the dialog box appears check the monochrome box down below. Drag the green to 200 and compensate the other channels so that all the channels add up to 100%. Drag the red to somewhere around -80 and the blue to around -10, then click OK.
6.) Select the Background copy layer 1 change its color mode from normal to screen. Because it will be too bright, bring down its opacity to something around 36% or so.
7.) Double-click on the level adjustment layer in the layer palette and move the white slider in the OUTPUT levels section at the bottom to the left a bit, and click OK.
8.) In the background layer 1, raise the opacity a bit if you like. Then add a Gaussian blur to this layer 1 (e.g. Filter > Blur > Guassian Blur). Set a radius of 5 or so and click OK.
Good luck!
