We all know dust comes mainly from us right? How come when captured on camera they appear so perfectly round?

I am going to try a little experment of my own...

I am going to gather some dust (shouldn't be hard all I need to do is lift up our dvd player lol)
And then any that I have gathered I am going to get gary to blow on to it and with my camera take multiple shots (shutter speed) and view them to see if it really is just dust

sounds like a plan eh?

Well, not being sarkie with my reply: It's my bread and butter to know such things.

Can it be proved?
YES! Just take your digital camera (for fast results) outside and throw some dust out in from of the lens and presto, multiple orbs will appear in the picture! Note; the dust has to be within 4 inches of the lens to appear as orbs in the photo. You can also take a spray bottle to simulate humidity and spray directly out in from of the lens. Result will once again be multiple orbs.


The above diagram is a representation of how dust in front of the camera lens appears orb-like when a flash is used. "B" represents how light travels through the camera lens, and "A" represents the focal point of the lens, or the point objects need to be past in order to be in focus. As you can see, there are dust particles closer to the lens than point A, therefore the dust will appear out-of-focus, as seen in Diagram 2. When the flash fires (Diagram 1), light is reflected off the dust, back into the camera lens, causing the dust to be illuminated. Because of the angle of the flash and the camera lens, the closer the flash is to the lens, the more prone it will be to dust orbs. The same applies for using nightshot video cameras, the IR light reflects off the out-of-focus dust, causing them to look like "orbs" or plasmoids.



Point "P" represents the distance the dust particles are away from the camera lens, and "A" again represents the camera lens's inverted focal point (the point that an object must be past to be in-focus). This diagram shows how dust particles become out of focus as they get closer to the camera lens.

I'm sorry Geri_Mars but it's a fact.....

But if you don't wish to take my word for it:

From Wikipedia http://en.wikipedia.org/wiki/Liquid_orbs

The term orb describes unexpected, typically circular artifacts in photographs. Sometimes the artifact leaves a trail, indicating motion.

The technical photographic term for the occurrence of orbs, especially pronounced in modern ultra-compact cameras, is backscatter, orb backscatter or near-camera reflection.

Causation

Due to the size limitations of the modern compact and ultra-compact cameras, especially digital cameras, the distance between the lens and the built-in flash has decreased, thereby decreasing the angle of light reflection to the lens and increasing the likelihood of light reflection off normally sub-visible particles. Hence, the orb artifact is commonplace with small digital or film camera photographs.

The orb artifact can result from reflection of light off solid particles (e.g., dust, pollen), liquid particles (water droplets - especially rain) or other foreign material within the camera lens.

The image artifacts usually appear as either white or semi-transparent circles, though may also occur with whole or partial color spectrums, purple fringing or other chromatic aberration. With rain droplets, an image may capture light passing through the droplet creating a small rainbow effect.

Underwater photographers notice the effect also, which occurs for the same reason as above-water photographic artifacts. Sand, small sea life or other particles close to the lens, invisible to the diver, reflect light from the flash causing the orb artifact in the image. A strobe flash, which distances the flash from the lens, eliminates the artifacts.


And I didn't for a second think you were being sarky.... You either know of the phenomenon or not. But now you do...
