Maybe I can start abit and others correct me if I am wrong.........
it's either modify or use a filter. Not both.
If you modify, it will be a dedicated IR camera, so no more normal shooting after the operation unless you re-modify back.
Maybe you could join the IR group in Singapore when they go out for their outing.

filter means.. you have to use a tripod, mount camera, compose, put filter over, shoot.
this is because you cannot see what you are shooting with the filter over the lens.
this is an exception when you use prosumer or p&s, you get to see live view on lcd. but long exposure still required, so still need tripod.
remod means, they zhng your camera, open it up, replace something over the sensor with an ir filter. you get to shoot ir handheld speeds, can see what you are shooting, albeit not in ir color, but normal color (like normal shots).. but your shots come out in ir form.
if you remod, you can never shoot normal colour again unless you zhng your camera back to normal.. but no one ever does that.
it can be both...
let say..you operate ur cam with infrared @ 400nm...
u also can use Hoya R25a(red filter 650~665nm)) in front of the lens
or Hoya R72(720nm)
then u will get another unique tone
...
mod the cam is not always use R72 n ELP
(now i'm using 695nm for my d70)

We used to have regular IR Outings. But recently many of the regulars have been very busy with work and we've slowed down for a while.
Just keep a lookout here for the Outings.
interested in IR photography too.... some questions to ask:
- y is it tat when shooting IR i cant look at wat i shoot in the 'viewing hole'?
- is taking IR the same as taking normal pics? cos u mention long exposure still required, so need tripod
- IR photography 100% need to use photoshop etc to edit ur pics b4 it looks nice or normal shooting can acheive the nice shoots liaoz?

1) the ir filter over the lens is nearly opaque. you can actually see through it when held up in front of your eyes, especially when facing the sun (though it is not recommended to do this for long, you will burn your retina if too long since it only filters out certain types of light, i think). if i put my hand (opaque) over my lens, can i see anything through the viewfinder?
2) it CAN be the same, but you need to deliberately modify your camera. but no matter what you do, infrared photography is obviously not color photography in the sense that you get unique tones and characteristics. actually i'm not sure what you're talking about here. if you use a non-modded cam - i.e. r72 filter over lens, you will need long exposures unless you want to risk softness by opening up aperture and pumping up iso.
3) if you are proficient at tweaking your camera settings, obviously anything can be done out of camera. if you wish to get BLUISH tones rather than SEPIAISH (this is using the ir forum white balance procedure).. you will need photoshop to carry out a procedure called channel mixing though
Wow sure learn alot of new stuff. but how much does a IR filter normally cost?
Depends on the size, can be anywhere from $50 to $150 or more
