There are certain caveats troytime. Unless your camera is modified, just using a filter will take extremely long exposures. This exposure took 5 seconds. You can't handhhold it. It pretty much only works outside. It is great for landscapes, though.

I'm not discouraging you, just make sure you get a tripod first or you'll be disappointed.

What do you mean, modified?

Basically, you take out the infrared blocker above the camera's sensor. It is a thin layer of glass.

Then you replace the blocker with a custom machined piece of regular glass that does not block the infrared at all.

Screw on a hoya filter, then you can hand hold shots at normal shutter speed.

Usually, this involves adjusting the camera's focus as well.

OR

Some people replace the glass above the sensor with an infrared filter there, that way you don't need a filter on the outside.

Just depends

you dont need to modify your camera at all, thats what the R72 is fro

D70 with a Hoya R72, this was around a 10 second exposure IIRC

the Hoya R72 IR filter is a 10 or 12 stop filter, meaning it lets in 10-12 stops less light then the lens without the filter

looking at it its basicially black. if you hold it up to a light you can barley make the light out

He was just asking what modified meant - just as Anubis said - you can use 'most' cameras with a filter. If you want to handhold portraits and action shots, it needs to be modified.

All cameras are different in sensitivity to IR - my canon a630 grabbed my exposure in 3-6 seconds depending on brightness. The D70 above takes 10 seconds. Some cameras are 'more' or 'less' sensitive. The easy way to tell is to take your camera in a dark room and point a standard tv remote at it. Tv remotes are infrared - if your display lights up real well - your camera is fairly sensitive. If it doesn't light up so well - then not so much.

One advantage of some P&S cameras is that you can compose on the view finder. My A630, I can see the scene just perfectly on it's flip screen in infrared.

I like the black of the water in that pic btw

That looks like it would be a great shot in real-life color.

Awesome shots. Do you think this filter could be held in front of the lens of one of the older Sony Handycams with the Night Shot? NS is strictly IR, so their sensitivity is extremely high. That would make for some really cool video.
