IR filters are used during daytime, especially when there is bright sunlight.

If u want to test the filter, point ur DC on a likely IR emitter like a light bulb or fluorescent lamp.

It may be hard to see the target, so set ur ISO to the max. Exposure would depend on the sensitivity of ur ccd to IR, so got to experiment.

If u have "one touch WB" like the Olympus models, use it.

IR pics should have a reddish tint to it...

Welcome to IR photography! U'll luv it!
 

thanks for the advise.

i try it tommorow, then see what is the result.

Thanks....

Klause, I think u r like me, never touch the manual in the installation CD right? :bsmilie:

If I can remember offhand:
Press the ok button
press down arrow for WB
select the last option in the WB menu
try to aim at something white, then press the ok button
the dc will take a pic and calculate the WB (I think).
That's it! :D

Common light bulbs don't actually emit infrared radiation. Not sure offhand about flourescent. The flash will, but unless you've got a powerful, powerful flash, you're unlikely to get an exposure. Best to wait to daytime.

Sorry abt the wrong info :(

I'd taken an infrared on flourescent lamps, so can try on them :)

No problem, we all make mistakes! It is after all a fairly common misconception.

Thanks Jed! Since we're on the topic of IR, I've a question:

Would it be possible to illuminate an object with IR LED torchlight and shoot it with an IR filtered DC?
 

No idea I've never come in contact with IR LED torchlights... but assuming it emits near infrared radiation, then yes.

Guess I'd have to try it then.....
