ultraviolet images.

08/24/2007 1:03 PM

does anybody know where I can find images of ducks and geese under ultraviolet lighting conditions with a camera that converts the ultraviolet into the human visible spectrum?

I have searched google and yahoo exhaustivly for the last three days and come up with nothing except a couple of images of goose decoys.

I don't know but would like to see them when you find some! You might try duckhunter.net-- the folks there may be more likely to point you in the right direction. Good luck.

Most B&W film is very sensitive to blue light. Some spectroscopy film is especially so. A good, deep blue filter over the lens should yield near UV images with conventional B&W film. Contact Hoya or Tiffen for filters. Also Baader, a German mfg of astronomical optics. And call Kodak for info on films, filters and digital imaging..

If you know someone in the military, get them to rake a picture for you.

A true UV camera will not be cheap as it will have to use at least quartz lenses to see down to 140nm. Better quality systems will use either magnesium flouride or lithium flouride to see down to 120nm. Your best course is as suggested in post #2, this won't be true UV but will be as close as you can get without spending a small fortune.

Jake, I'm glad that you found the UV images you needed. Can you tell us why you wanted them?

I was trying to determine if some new products for waterfowl hunting are just a bunch of hype or if there is some actual fact behind their claims. There are two products, one which claims it blocks all of the UV reflection to make the decoys look more realistic and the other one claims to enhance the UV reflection to make the decoys look more realistic. After reviewing the photos, I have determined that both claims are partially true. Some areas need to be UV absorbing and some areas need to be UV reflective. I think I might go ahead and buy a small container of each product and do some touch up by black light to try to simulate what the birds might actually be seeing.

Thanks for the explanation. A quick search on Google shows a fair bit of research into birds UV vision. Good luck with your experiments.

yes, it does show research, but I wanted to see actual images and they were very difficult to find.
