    New here..... I have a question or observation or ?. It seems the IR is the key here, and the cameras only support the available IR ability. Why not night scopes like the IR type, you know the Ebay stuff thats like Special Ops kind of military stuff? Are we not then in the same ballpark? I don't doubt theres something to this. Funny, this all started reading about the 'Blue Mist' method, or tales about the blue mist.

    Most night scopes just amplify available light. While i would like to have one to play with, I do not think they would be useful to find gold.

    I'm not meaning the green view night vision ones, rather dedicated infra-red goggles/scopes...?

    I'm not sure the phenomenon can be viewed in real time. At least I haven't heard of it.

    i caught this glow with a ir lens,after a heavy monsoon down pour. you could not see the glow by eye or with binos before the shot or after the shot. i belive it catches the gases coming off of some sort of a chemical reaction.it didnt show up days later after the rain.gases on this one must build up then release when the ground opens from the rain. i like the shot to be much darker,this has not been worked by a photo program.Click image for larger version.

    Its possible to capture on digital cameras. By theory dogs can be trained to scent deposits.

    As far as seeing anything below the surface goes, no one suggests that. The aura is captured above ground and indicates the presence of gold underground.

    Poor analogy, but it's the same thing only different

    I don't think it's so much not having documentation to prove it as much as getting their reputation dirty. A lot of "scientists" are not willing to step outside the dogma box.

    Ahaulil is correct the "night vision" goggles & scopes only amplify the available light. FLIR is working on different frequencys of the spectrum.

    If you are having difficulty finding filters for the Cokin square filter holders check out the local camera store. Hoya has plastic sheet filters that'll fit with a little scraping with an exacto knife. Another use for the plastic filters is if you are having problems finding filters to fit your camera, but can find another you can remove the glass filter & use it to trace a pattern on the plastic Hoya filter to make your own.

    If you save the corner scraps you can use them to cut small filters for cameras like Nikon CoolPix. You'll be able to hold them in place with two slivers of masking or scotch tape.

    The good part is you can usually get two - three filters from one sheet that costs less than glass filters!
    I know it's here, just need a bigger coil!

Going by that experience, perhaps the spot above the pot and the spot in the desert photo might be an indication of a gold deposit, (or silver).

    As far as your pot is concerned; though it's an excellent idea, you might want to have ONLY gold, or ONLY silver in the pot, until you are sure of which color is which for each metal.

    All in all, I was wondering what make/model camera you are using and if possible, what program for the enhansment of the photos. I'm new at IR with digatal cameras, and though I have some promising photos, my program won't enhanse them like the ones I've seen in instructions.

    Good luck with this technology and keep us informed on further developments.

    hey Eagle, can you tell me more about the film type IR photos? Can I do the same thing as you back in the 80s? Thanks

    I can give you all of the basic information, but I no longer remember the film designation. And, unfortunately, I lost all of my journals in a fire several years ago. So, for the basics:

    My partner and I hired a small plane to transport us over the site. This has to be a "high wing", to be able to take the photos, as you would be taking them straight down. (We found that a helicoptor does not work, as for some reason, the air turbulance neutralizes the effect)

    We flew at an altitude of 1,000 feet, at a little above "stalling speed". As stated above, the photos were snapped while pointing the camera straight down. If I remember correctly, we were using a 45mm Nikon. But, it should work with any 45mm (film type) camera.

    We sent the film to the manufacturer in NY to be developed, instructing them; (this is important to remember) NO COLOR CORRECTION. And for them to make the finished photos into slides.

    When the finished photos (slides) were returned, we put them in a slide projector to view them on a screen. Then, we located each photo that had the blank (or white spot) on a topo map. Of course, with the advance of technology, I'm sure there are better ways of doing this today. Then, we went to the area and dredged the area where the white spot showed there should be gold. And, there was!!

    There use to be several types of 45mm film on the market, but now, since I haven't kept up with that particular technology, I have no idea what might be available. Especially since digital cameras are so popular.

    Incidently, I didn't develope this myself. If you can find an early 1985 California Mining Journal, you would find an advertisement in it. Basically it said; I can locate a mass of gold equal to 12 quarters (.25 cent pieces) beneath up to 12 foot of overburden. And, as we found out, the guy wasn't lying. Anyway, that's how I originally got the nominclature of the film and other info. We tried it out a couple of times after that and the results were always positive. Afterwards, my partner died of cancer, then my wife passed away and I kinda lost interest in a lot of things for a few years.

    Anyway, I think I've covered everything. If you have any further questions, feel free to ask.

    Eagle

    Oops, I need to clarify one thing; That altitude of 1,000 feet is above the ground, NOT ABOVE SEA-LEVEL.

    Experimenting with metals auras

    Dear sir.
    I m Nelson from Santiago, Chile SA.
    Since 1982 i starter to join metal detecting hobbie and today with some years of expirence i had tried diferents kind s of metal detectors and also long range detetors. Today i m ready to experiemnt with gold auras has david Villanueva pointed on his book.
    My equipments is a canon 350D, a 720nm IR filter, fitted to a 300 mm sigma lent.
    Today i m mounted my camera on a tripod and took a few pictures just on my garden were i know there are some metals spreed under my grass after my home was build. All in all after i took the pictures with diferent settings on my camera i process the pictures with arcsoft photostudio and i got the results i m posting here. Then i check this with my metal detector and gave me what i think is a match of what my camera was showing, because i got a signal on the spots that are blue on the picture and also if you look cloe to the upper left side of the picture, you will see something like an aure that is not 100% on the center of the picture. However, and appart of the metals that i know are undergrouind on my yard, there are also two copper water pipes.
    The best settings of my camera were, ISO 400, speed 125, and 4.6 apperture of my lent.
    Sorry for my english, but i think is important to share my first expiriencies with metals auras.
    Soon i will get more pictures and post it here.
    Best regards
    Nelson

    Eagle,

    First off, my condolences for your loss.

    I'd like to know more about this. Does it work in wet humid areas? Swamps and such?

    Has anyone published a study, that you know of, showing the relationship, or differences, between the old wet film produced images verses the digitally produced images?

    Both can be adjusted to filter specific portions of the IR spectrum, what about 820nm, digitally?

    Can you filter post image for the wavelength, or must you only capture the wavelength initially?

    Thanks in advance

    It would work in swamps and/or humid areas. We were taking pictures of a river and it showed deposits of gold in 5+ feet of water. As for the studies, I haven't run across any. I'm just barely started in digital work, so I don't have a definitive answer for that yet. I have tried several IR lenses and found the only one to give readable results is the 720nm. That is also what David Villanueva recommended. If you're asking if you could take photos and then process them to see the aura, I don't think so. With the correct IR film, the process is done in the act of taking the photo. When the film is developed (with no color correction), by projecting the slides, you won't see an aura per se, what you will see is a white spot where the cache or gold deposit is.
    We proved this out by dredging in areas that really looked good, but the photos didn't show any anomallies and found no gold. Then we dredged the areas that showed white on the film, and came home with nuggets that were up to 2 oz, but, I'm not sure how well it would work with silver as my prospecting experiences have always been centered on gold.

    I hope this helps a bit.

    Eagle
