本人最近買了部Canon860i, 發現每當影夜景時(使用閃光燈), 會有一點點正圓形蒙點<像'水珠'的東西>在相片中, 但我問過影音鋪職員話這種現象是正常. 請各位朋友可否告知是正常還是部機有問題?

影夜境做咩開閃光燈？
影人嗎？

<像'水珠'的東西>可能真係水珠或者係塵...
影夜景唔洗用閃光燈...如果係影維港對岸...難道閃燈夠照亮成個環境嗎...
應該係用腳架同慢快門...

SORRY!離一離題,我想問下你係邊度買,幾多$,

因為設計上閃燈同鏡頭放得太近, 好易比空氣中塵粒反光返入鏡, 3星有D型號都係咁.

清楚了, 多謝各位朋友意見.
另外回覆yee929先, 我係Fortress買的2990, 包2G咭, 腳架, 相機袋, 保護貼, 附加電池, 最好就有個card reader(能support SDHC).

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
