It is well known in the circles of photography and by the camera manufacturers themselves, that the phenomena of 'orbs' on digital photographs are nothing more than environmental factors, e.g. dust, bugs, pollen, lens flare, moisture and even hair. These images are recreatable and we have conducted our own experiments to prove this and regularly test out new cameras. The overview of our experiment can be found in the article Orbs - Dust or Real
Below are some of the photographs that we have recreated as examples of these environmental factors for the purpose of giving you something to compare your own photos with.
