之前聽過人講話fz10會出現blue同red點,發現原來佢有時會在長時間曝光卻沒有做noise reduction既step,藍同紅點因而出現!!!!

假設原因:可能係佢本身就有尼d死點or熱點(都唔知係咩點),但pan記就以noise reduction既方法來逃過我們的法眼.
解決方法:
1:送翻老家鄉"panasonic"搞下
2:在menu中選reset,便會自動回復noise reduction的功能,但何時病發還成一個問題!!!

註明:此問題只會在慢快門時才出現,如各位出現其他情況,或優化方法,請分享一下!!多謝

只有在連續拍攝及在慢怏門下才沒有做noise reduction的。

正常來講拍完慢快門相的時候會等數秒時間(那藍色的畫面),那幾秒就是在做noise reduction,連續拍攝是不能在慢快門時使用的

This exist in most if not all consumer grade DC
It appear in long exposure shots.

但係正常既機應該係全黑garｗｏｒ
點會出左咁多紅藍點

[GeorgeWong]

錯，連續拍攝是可以使用慢快門的。

可以嗎??
但到了如1,2秒快門時他連拍的logo打了一個交叉(x)

我沒有這方面的問題!

In small sensor (CCD) the electric signal is very low especially in this almost dark situation. It is therefore the Noise to Signal level very high.
The red and blue are the noise (ie signal not coming from the light source)

In software, you may select those total dark area and set the brightness to minimum.

Happy shooting !
