Is there a way to convert a normally colored photo into a color infrared photo using image software like Graphic Converter, Adobe Elements, etc.?

There might be some simulators out there, but there's no way to get true infrared without an infrared filter. The simulators make guesses based on color values, but wighout blocking out visible light at the time of shooting, there's no way to remove it and leave only IR later.

No! Well as far as I know. There is a way to simulate the Infrared look of a photo using post processing. Basicly you wash out the green channel and add blur.

| If you're considering purchasing an infrared filter (that is, a filter which only allows light in the infrared band of the electromagnetic spectrum through) be advised that digital cameras typically have a filter which blocks infrared light from hitting the sensor. The F717, for example, has one which slides out of the way in the nightshot mode. This means that, even if you get an infrared filter for your camera, you're not going to get optimal/satisfactory results without doing something about the filter. I believe there are a few sites out there which document the removal of the filter and replacing it with a clear piece of glass. They're strictly model-specific, of course. |

I believe daysez has it. In photshop you can play with the green channel and get the effect you want. I did it with some video long ago in Adobe Premiere, and I'm sure it's a similar method in Photoshop.
As for what Jimmythefish was mentioning... it's true. If you are looking for a infrared filter you will want to be sure your camera can in deed a) take filters (and what size of filter you need) and b) if your camera has a hot plate which prevents IR from being pulled in. One of the easiest tests to see if your camera can in deed see in IR, is to take a remote control (like for your TV) and point the remote at your camera's lens. While looking at your camera's preview screen, press a button on the remote. If your camera can see in IR, you will see the remote's bulb light up whiteish/blueish. If you see the bulb remain dark (like with the naked eye) then you have a hot plate and it isn't designed to pull in IR.
The camera's I know that work with IR are: Canon G1, Sony S85, Sony 707. In fact this is one of my favorite digital IR photographers //www.pbase.com/image/9495704 He uses the Sony 707. Most though, don't leave the funky colors. Most shoot IR in black and white the duotone it in Photoshop or leave it B/w.

The best IR camera's out there are the Nikon Coolpix series (early model), Canon Pro70, and the Sony's are incredible. I have a Pro90 that is great. People who are really into it take the 990 and remove the IR filter OUT of the camera making it almost solely an IR device. This guys stuff is incredible and he uses a cut up 990... //infrareddreams.com/
NOTE!!!! If you want the funky colors like you posted you must use a Hoya R72 IR filter. This is actually a NIR filter (Near infrared up to 700nm). So color will trickle through it is a deep, deep Red filter. If you go to true IR filters (87,87C or an 89) you will get dominantly BW images because it is a black filter and truly cuts all visible light...
//www.cliffshade.com/dpfwiw/ir.htm This is a great site for IR information. Read it from top to bottom... From this site about your camera...The 3.34MP Nikon CoolPix 990 is considerably less IR sensitive than the 2.11MP 950—enough so that several RPD correspondents have given up on the 990 with deeper IR filters like the Wratten 87 series and the Hoya RM1000, all of which work quite well on the 950. The IR sensitivity of the Nikon CoolPix 995 presumably equals that of the 990.
IR is great stuff. Enjoy!!!

There is a way to fake color infrared. It has something to do with switching the green and red channels or something in photoshop. Do a search on google.com for flase infrared or faking infrared. I'll try and find the page agian too.

| I have tried my sony f717 for IR, and so far its OK, but Ive tried it with an old floppy :-)...It works grate, but there is a problem if you want to shoot close ups, the dark foil from the floppy reflects the IR beams form the camera...I hope that if I buy hoya r72 I wont have this annoying efect...If someone used hoya r72 and sony f717 please let me know abouth it...I dont want to spend my money on the filter if it doesent work good with the camera.. |

Williem merged 2 images and got:
doesn't really answer the question but a merging of 2 differently processed pictures may give you the effect you are looking for.

| Nightshot mode on the Sony's with the addition of a infrared filter is a superb combo. |
