即係張相remove左hot pixel,淨低d noise~

下次我用ISO50/100~~^^

o個o的其實都係noise黎..不過唔係hot pixel

菲林才有微粒，ccd那些也是叫noise...

如果是用 ISO 200, 咁出來的效果算係咁的了.... 因為拍夜景, 想靚就用 ISO 50 啦. ^_^

這些是粒微粒... 唔係 noise 來的, 所以應該唔關 NR 事.

CANON機入面，當快門時間長而開o既nr

係用黎remove hot pixel的...

唔係remove 高iso o既noise...

唔如唔係，咁佢一定會係咪都開nr啦..

你地覺得NR有問題嗎?

I agree with digiboy , because I am also Canon user

under ISO 200 ever 400 the DC with NR works automatically.

You should send you DC back to canon and check what is the problem. I am going post another photo which

was produced under ISO 400, you may take it for reference.

ISO200 F8.0 4"

Which ISO did you choice.
