大家給一個意見！

本人剛同朋友員買了部CANON IXUS 850 IS 行貨版，影日間相十分不錯，很滿意，但影夜間相就很有問題了，用自動模式跟閃光燈同步影相，大部份相片約90%都顯視出不規則白色圈，朋友當然激氣，拿回尖沙咀CANON公司修理部檢查，數日後維修師傅回復機身功能正常，defect可以接受，不再處理。

這樣的大公司，一流服務，九流技術，(明歌星劉德華都話，今時今日的服務態度要改啦)。簡直一肚火。
朋友當然不會罷休，己去消費者委員會投訴，真有效率，即時跟進，將有問題相片存檔。其間已知有幾個用家都中招。心態真是有苦自己知！

Sorry，Post張相睇睇。
咁講好難理解張相搞成點。

Causes and solutions

Causes

There is always a certain amount of dust floating around in the air. You may have noticed this at the movies when you look up at the light coming from the movie projector and notice the bright sparks floating around in the beam.
In the same way, there are always dust particles floating around nearby when you take pictures with your camera.
When you use the flash, the light from the flash reflects off the dust particles and is sometimes captured in your shot.
Of course, dust particles very close to the camera are blurred since they are not in focus, but because they reflect the light more strongly than the more distant main subject of the shot, that reflected light can sometimes be captured by the camera and recorded on the resulting image as round white spots. So these dots are the blurred images of dust particles.
You can reproduce this problem relatively easily by taking a picture right after you put away goods that create a lot of dust, such as feather bedding.
In actual photography, this problem frequently arises in shots taken at construction sites, etc. It may also occur when it is raining or snowing. Compact cameras in which the flash and the lens are close together are particularly susceptible to this problem.



Solutions

· Make the surroundings as bright as possible so that you can shoot without using the flash.
· If the flash is detachable, hold it away from the camera.
· Take the picture in a less dusty location.

各位高人教我如何簡單上傅有問題相片？

☆另Dragon King人兄所上傅圖片(和有問題相片大致相同)及解譯正確。

但不要忘記，購買DC?瓜相機，都是一般用家及師奶，去到邊影到邊，那有尊業人仕識走位影靚相呀。

本人認為，作為一個消費品，產品如有問題,技術未能解?，就不要推出市場賣，要有商業道德，如有defect，就要在產品說明書注明，讓買家清楚可以選釋買或不買。

樓主，

如果你認同 dragon king 的解釋，那便不是相機的問題了。

那是現場環境的問題。

除非你認為你的問題與 龍王 的不一樣。

清楚解譯說明一點，本人只認同一部份，因拍攝夜景地方是在土耳其，天氣很好,沒有雷雨塵埃，相機內及鏡頭都很乾凈，因是新機，只用幾次吧了。再說明一點有部份團友用DSLR大機在同位置一起拍攝，都沒有問題，相很靚。團友解譯是相機質數設計問題，如鏡頭靚,CCD優良,設計閃光燈離開一點，盡量減少?光，就可以避免了相片1個個白色圈。

本人是門外漢新手，說錯了不要見笑。
