Infrared photography

There is times when I was really crazy about infrared photography. Coming from tropical country, the typical scenery beside blue ocean is green grass and trees. Unfortunately, it's quite hard to find a place with multi color flower, or tree with white snowy leaves, so don't even ask for majestic autumn color.
But I guess photographer never lack of creativity and come with infrared photograhy. So what is infrared photography?

In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Usually an "infrared filter" is used; this lets infrared (IR) light pass through to the camera but blocks all or most of the visible light spectrum (and thus looks black or deep red).
When these filters are used together with infrared-sensitive film or sensors, very interesting "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect."
The effect is mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. Chlorophyll is transparent at these wavelengths and so does not block this reflectance (see Red edge). There is a small contribution from chlorophyll fluorescence, but this is extremely small and is not the real cause of the brightness seen in infrared photographs.
The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering (respectively) in the atmosphere compared to visible light. The dark skies, in turn, result in less infrared light in shadows and dark reflections of those skies from water, and clouds will stand out strongly. These wavelengths also penetrate a few millimeters into skin and give a milky look to portraits, although eyes often look black. (source : Wikipedia)

You might say, what are you talking about?? Well, I am talking about this... compare the following images!

To this!!!

Can you believe it was taken in tropical country???!!!

Yes, the last one was infrared photograph. It's looks pretty different and give you a different feeling. But, not everyone have a taste for infrared photography, but I know one who does really into it. Hendra Samudera of OneClick Photography (Jakarta) a wedding photographer, he and his colleague are expert in this area. All these images are taken from their website. (I can assure you they are very friendly bunch, I spoke to him before)

Oh yes, you said it is lovely. But what can I do when I don't have such device? Well, there is always GIMP and photoshop to help you. I find a great tutorial here.
