I remember watching a documentary on google video sometime last year, where they messed with the settings on a camera (something about exposure I think?) and showed that 'objects not usually visible' could be seen in the sky. They did side by sides with normal and this setting to show this. Does anyone have any information on how they achieved this and whether what they were seeing was cleverly editted or real? Considering the lack of coverage here, I'm guessing it may have been debunked in some manner.

EDIT - I did a quick google search on the off chance and I think the condition I was looking for is low-light. Supposedly in low light filming in normal conditions shows objects invisible to the human eye. Is there a plausible explanation for this?

You mean like heat? Sound's interesting, never heard of it tho..

I dont think it was thermal imaging because it just involved changing settings on a normal camera and the picture wasn't all colourful, it was sort of sepia-dull (not sepia hued though).

I'm going to try and search out which video I saw it in as reference.

What you need to do is get yourself a digital camera that is capable of detecting Infrared. Some already do to various degrees. My little Nikon L6 does to a good extent. Then, you get yourself...aaah - hold on.

This explains it better. Just don't use it for the wrong purposes.

Ahhh thanks Digital Sentinel.

What would the wrong purposes be? I assumed that bit about seeing through clothes at the end was a joke..? haha

Umm... if the camera is tripod-mounted, and you use a VERY long exposure (often using a manual shutter controler: a little button attached to the camera with a long cord), then you can take pictures "at night" that almost look like daylight. Objects that the human eye would not be able to see are thus rendered visible.

This relies on their being SOME light however, it doesn't work in pitch blackness. (conversely, if you are looking at objects in the sky, then they must either be emitting light, or must be illuminated by some source, if only very weakly).

it also relies on the objects being stationary.

Meow Purr.

Like I said...

Thanks for the informative replies. Knowing now the method, do either of you/anyone else know anything about using this method to 'reveal' unseen UFO's? From what Ships Cat said, it does seem plausible, though I do wonder to what extent perspective comes into play (for example, whether an orbiting satellite would be visible via this method but 'appear' as a ufo alot closer)?
