That's awesome! Kinda looks like something out of a fantasy movie.

Very nice Fred, it's good to see those IR shots again, I didn't know that the FX is capable of IR too. Well, at 1 sec you better have a steady tripod :-)

Thanks for the comments.

Max -All digicams have internal infrared blockers (sometimes called hot mirrors) to control the amount of infrared light reaching the ccd.The weaker the blocker, the more ir sensitive the camera. The vast majority of digicams have prohibitively strong ir blockers and are essentially useless for ir photography. For the few that are sufficiently ir sensitive, the use of an add-onfilterthat will block all but the infrared wavelength (~700nm) is what is needed. The hoya r72 is the most popular and reasonably priced; ~$40.

As mentioned, there are not many digicams senitive enough to ir. The fz1/2 isgood and can get handheld shots in the 1/20s range. The fx01 isn't quite as sensitive and requires longer shutter speeds but can still get the job done, as seen above. IMO, that's about it for Panasonics. The minolta dimage 7 is another good one as is the sony 707/717 which allows for the internal ir blocker to be physically moved away from the ccd in nigh scene mode. The oly c2100 is another good one.

Awesome shot Fred! Dreamscape is right! I can never decide which I like better, with the colour swap, or just a levels adjustment. Some I like both. Keep 'em coming.....Don.

Donna's "dreamscape" is a very apt description. Apparently some animals see ir light. Would they see this scene this way? Perhaps we are unconciously sensitive to to their spectrum but we "see" it only when we are in a dream state.

Why is the red/blue color swap appealing? Probably for the blue sky. It also gives the foliage a red tint which seems to conform with the term "infrared" - more "authentic". I guess thereareendless possiblities for different color swapping. Or just gowith b&w. Here it iswith a simplemonochromatic sepia rendering via irfanview, which is not far from the color you get if you set the custom wb to florescent lighting throughthe f72 filter.
