维基关于照片里出现的orbs(亮圈)的详细说明：
http://en.wikipedia.org/wiki/Orb_(optics)
The term orb describes unexpected, typically circular artifacts that occur in flash photography — sometimes with trails indicating motion — especially common with modern compact and ultra-compact digital cameras.
Orbs are also sometimes called backscatter, orb backscatter, or near-camera reflection.
Orb artifacts are captured during low-light instances where the camera's flash is used, such as at night or underwater. The artifacts are especially common with compact or ultra-compact cameras, where the short distance between the lens and the built-in flash decreases the angle of light reflection to the lens, directly illuminating the aspect of the particles facing the lens and increasing the camera's ability to capture the light reflected off normally sub-visible particles.[1]
The orb artifact can result from retroreflection of light off solid particles (e.g., dust, pollen), liquid particles (water droplets, especially rain) or other foreign material within the camera lens.[1]
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.

YES! Just take your digital camera (for fast results) outside and throw some dust out in from of the lens and presto, multiple orbs(亮圈) 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. Our conclusions are that dust particles reflect light from the flash and appear as perfectly round balls of light in the photo. Try it!

回复 23# 雪影狂刀
哈哈哈哈。。。。。。。。我无语以对。。。
我开此题是讨论烟供法之事。。。。。不是讨论摄影之事， 离题之事我不再回应。。。。。。对不起大家，谢谢体谅。。
別帶頭離題好嗎?
告訴了你照片白點的原因,不接受也就算了還拼命否定大家給的解釋.
現在又拿類似的東西出來"考驗"大家,你是安甚麼心啊?
前面那幾帖擺明你只接受你預想的答案...這個樣子,如果還有人願意解釋原因給你聽的話,你可要好好的感謝他了.
我不認為學佛是為了追求神通異像,所以即使真的看到了,也沒必要去理會(更何況那擺明是自然現象).
就醬,bye |

请各位大德，请问这里面的东西是如何造成？？？
chowsekky 发表于 6-1-2011 04:29 PM 
法师说法时，寺庙里都会点檀香的吧，能嗅到香味时，飘散的香粉尘埃就已经很浓了。
强烈的灯光被香粉尘埃漫射造成的，而且近距离才看得到。 |
