Many digital cameras have a filter that blocks infrared, whether the FZ30
does I don't know. If it does then exposure times will have to be quite
long, if it doesn't then they should be in the same general range as
visible light exposures.


Not correct apparently. See

What's not correct? That many digital cameras have an infrared blocking
filter? That I don't know whether the FZ30 does? That if such a filter is
present exposure times will have to be quite long?

there are a couple of images on that page taken with an FZ30.


Note the exposure times for the ones for which the times are listed.

The
biggest problem with IR photography is the inordinate expense of the
filter. Whoops! Take that back, they're bloody expensive here in NZ but
I just checked on eBay & Hoyas are around US$30.

Go for it, kid! ;^)

From what I've been testing, all current and recent digitals have an IR
blocking filter, it just varies in strength. This was not the case if
you go back a few years or more. In fact they seem to have been getting
stronger over time. Certain older models are very popular with the IR
community, as they either have no or only have a weak IR block filter
and thus can be handheld and used for people photography, unmodified.
Of course it is possible to remove the filter or have someone else do
it.

Cheers,

Wayne
