Panasonic FZ30 Infrared Performance
Hi All,
I've just uploaded an article exploring the infrared photography potential of the Panasonic FZ30 http://www.dimagemaker.com/article.php?articleID=559 It joins the list of now 16 cameras I have tested for IR performance http://www.dimagemaker.com/specials/digitalir/digitalir.php Cheers, Wayne Wayne J.

And also isn't the camera only working within wavelenghts we can see and not really infrared - or am I mistanken in this? Kind regards Bruno |

Kind regards Bruno I am currently interested in this idea, merely to try it out. Speaking from a position of vast ignorance I understand that most/many digital cameras can process light through the standard, visual, spectrum and also are receptive to infra-red light. With an appropriate filter one can eliminate the visual spectrum and, with a longish exposure, leave only the infra red to activate the sensor. Naturally an infra red picture has a somewhat different appearance to a "normal" picture as various elements in the landscape emit or reflect infra red somewhat differently to the way they do the standard visuallight spectrum. Interestingly I have read that the FZ30 can handle this but my usually very good photo shop told me that it cannot as its maximum exposure time was too short. I think that they are wrong and will get hold of a suitable filter and try it out myself. If anyone can add to or corect this this then please do. Bill |

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.

To prove it, look at the front end of your TV's remote control while holding down one of the buttons. See anything? Now try the same thing while looking at it through your camera's electronic viewfinder. |

Thank you - that was enlightening :-) I can see some very interesting uses for infrared photography being this is something now in the hands of the normal consumer. One more possible stupid question! Could one use a software filter to get out the infrared information from any image taken with a long exposure time, from say night shoots, or is the information gone from normal pictures? Kind regards Bruno |

Hi Bruno,
Infrared photography (with amateur equipment) just gives a different look. Leaves and grass tend to white (if you convert the image to BW). It cuts through haze. Skies darken. It is just another option for photography, which some like. The sensors in digital cameras have sensitivity outside the visible range, both UV and IR. Effectively all current digitals have an IR blocking filter that reduces (but does not eliminate) the camera's sensitivity to IR. Cheers, Wayne Wayne J.

Hi Bill,
You are right. The FZ30 is certainly capable of IR photography, as the images show. Exposures in the 2 second plus range work. Cheers, Wayne Wayne J.

You can't extract the IR info from a picture that is not taken with an
IR filter, as there is no way to separate it from the generally much stronger visible light components. Cheers, Wayne Wayne J.

See http://digitalimagemakerworld.com/category/infrared/ there are a couple of images on that page taken with an FZ30. 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! ;^) -- Te Crumpler |
