| Seems like a slow day at DPC. It's a good question; and I'd bump it a little later, if I were you:) |

Krisby - sounds like the secret is an IR filter.
I had been wondering too, when I found your question, so did some basic searching on line and found several good introductory tutorials.
Give it a look.

Hope that helps!

| Not sure if it's why other people arent answering. but for me I thought infrared made things shades of white and grey. not colorful like the blue skies and green grass example you gave. maybe others are confused too. I don't know. |

I just bought an IR filter today. My 'make me happy present' since my camera has to go in for repairs. I'll post a couple in a few...
BTW - you can make them color or B&W. Choice is yours. :)
The first image I took on the way back from the photo store. Still trying to figure out editing but I know not to put most of the image in shadows. :) How to get rid of the purple...

The way I understand it you need a filter and a camera that lets in more infrared than most. I guess you can do it with all cameras but the shutter speed might end up in the minutes range. To get the colors like in the last example you need to change some of the color channels around. I'll try to find some links.

Well, I did learn some things today on the use of IR filters. The amount of sunlight and how it falls is extremely important. Most of the shots I took as the sun was setting had a definite light fall off. If I do it again at this time of day (early evening or even late morning) I will make sure the sun is at my back for a more even light source. The shorter your exposure, the more color contained in the image. My shots by 6:30 were getting extremely red even though I lengthened the exposure.
So, back out tomorrow to play and maybe find something zen. I got distracted...
BTW - if anyone cares, I was using about 25 secs at 400ISO at F8 on a 300D. But again, the light fall off was the cause of the low shutter speed. The ones I took this afternoon at 15 secs were much better but the light was stronger. |

Ok...this is what I do. I put the Ir filter on the lens...I then do a Custom WB (this part is imperative for the outcome) I then remove my filter and manually focus and compose. I then replace my filter carefully and take the shot. I then rely on my preview to decide if I need to alter my shutter. I always use the lowest ISO as possible.
Examples using this method.
  
In PS I generally adjust the levels, swap the channels and play with Hue & Saturation and Selective Colour. And that is it.
