QUOTE(greyPJ @ Dec 30 2006, 08:42 PM) now still have? or only when in foreign country? Yes, i tried a just now (5 mins ago) at home, the white spot still there. I don't think it is contamination or dirty lens as the location of the spot is in random position every time i take the night scene pic. I can see more white spot if i'm using ISO 800 and 1600. Can you try to take night scene pic using manual mode with ISO setting 800 or 1600 ? I hope it is not camera defect as i just took close too 250pics in Gurney Plaza using manual and indoor mode without problem. |

QUOTE(greyPJ @ Dec 30 2006, 09:29 PM) i just tried with my lumix, also got orb wor, so confirmed it is Flash orb, not defect. What was your setting ? The spot was less in your photo. I think you will get more with higher ISO and with flash on. Can you confirm again ? Thanks for your support  |

QUOTE(donnyyeo @ Dec 30 2006, 09:16 PM) LanEvoX is right. http://en.wikipedia.org/wiki/Orb_%28paranormal%29Flash orb is caused by light relecting off dust/pollen/droplet nearby the flash and lens. Fyi, flash orb can happen during bright outdoors too. However, they are not so obvious. My colleague manage to point out some flash orbs in my daylight photos. Flash orb occurs more frequently for small point and shoot cameras. It is because the flash unit is too near the lens. For a dLSR with a external flash unit, flash orb does not happen frequently. How to avoid it? Make sure it is not misty or raining Shot many photos. Move to a less dusty position. Turn off the flash for night landscape photography (the flash is of no use here)I almost 100% agree with the article. I start to believe it is orb that causing the problem. I just snapped another 2 photos with and without flash and i didn't see the spot without flash. So, it is confirmed the spot onlt present with flash.  I just curious why nobody discussed this effect in photograpy section before!  |

QUOTE(greyPJ @ Dec 30 2006, 09:46 PM) that was ISO 1600, i shoot again in ISO 1600, number of orbs still not that many, may be it is not that dusty over here. Thanks. I think i need to clean my camera lens before experimenting another night shot  Any recommendation on how to clean the lens ? Can i just bring my camera to any photo shop and ask them to clean ? thanks. |

I'm interested to see if Sony, Olympus or Kodak camera owners can post their pic using high ISO and with flash as well. Just want to compare how bad is the pic quality with diff camera models |

QUOTE(leonardtan2 @ Feb 1 2007, 02:36 PM) i had this problem before..only it was completly blurr with alot of white spots.. few questions, was it very cold in china ? coz cold weather can affect the picture quality. like gold3knight said, it's cause by condensation at the lens. juz use a camera lens cloth and gently wipe it. should be clear.. worse to worse juz bring the camera back and have the seller take a look at it. I don't think it is a condensation because i get the same problem when i'm shooting during hot weather in Malaysia.

If you can see the spot, then definately is the dust at your CCD This is from my experience  It is not appeared at the same spot. So, i don't think it is contamination on the CCD.
