Digital Infrared Photography using a modified Canon Camera, with this modification, I can shoot Infrared like images at faster shutter speeds compared to using IR filters mounted on the lens which needs a tripod due to it's slow shutter speed.

The camera is modified to shoot *30% IR + 40% Visible light + 30% UV. The result are very saturated yellow leaves, blue skies and 80% normal skin tone. Sample photo is the Sentosa IR and the rest of the colored images below. (*Specs is given by the one who did it. Don't quote it from me.)
The rest of the photos that have a brown tint or almost BW IR, a red filter is used, Shutter speed is still fast enough for hand held shots.
If you don't believe me. Just sit back and relax. :)

Seeing The Light…Not!
Infrared images are fun because they capture part of the invisible spectrum, allowing you to see some things that only register simply as heat creating otherworldly images. One of the first things you have to do when shooting IR images is forget everything you know about lighting and the best time of day to capture images. To give foliage that famed infrared glow you need to shoot at a time of day when there’s more sun on the scene than not; this puts you shooting at midday! Not the best time to make conventional images, but the “golden hours” for infrared. If you need a rule of thumb, try this: the best time of day to shoot IR is when it’s the worst time of day to shoot normal images.

Deciduous Or Not Deciduous, That Is The Question
In both film and digital infrared photographs, tree leaves appear to be white. This is a common effect produced by deciduous trees and grass because they reflect the sun’s infrared energy instead of absorbing it. There are many different varieties and sizes and deciduous trees lose all their leaves before the cold or dry season. Before that happens, the leaves often turn orange, red, or yellow and new leaves appear in the spring. Coniferous trees a.k.a. evergreens have small and waxy leaves, sometimes needles, which are usually kept all year and have a less intense response in infrared photographs.
