請高手們指教
我係用500D影的
有用腳架
M MODE
快門10"
光圈F8
ISO 100

點解影出黎都會有雜訊?
係我相機問題還是設定問題?
請高手們指教

長曝會有noise 係正常喎.

[rankinelo]

suggest you to check for the long exposure ISO reduction for this kind of photo in your 500D

因為你部係"digital" SLR
長曝一定有noise,
同埋你部係APSC, noise一定俾其他ching 用FF多,
你可以開左menu入面個長曝NR,
又或者影raw, 用software 執執佢就好.

多謝各位CHING指教

if 開左高光優先
黑色位係比冇開多d noise

Absolutely true and inevitable nowadays.....
for very long exposure say more than 5 mins, use film would be much easier.

长时间曝光，传感器发热，导致噪点。
