成日聽到話p記用高iso 影好多nose...
想請問一下,影夜景係唔係一定要用好高iso??
如果用低iso 影出黎有咩唔同??
咁點解p記要露出自己較弱的方面??

點解影夜景要用高iso 呢??
用低唔得咩??

新手問............~.~

低 iso, 得,
如果用腳架長時間曝光

[iphilip]

因為高ISO可以令曝光時間短d, 手震既時間都都知d.

至於係咪弱點, 就見仁見至, 因為一係就影到清晰但粗粒(noise)既相, 一係就影到幼滑但濛查查既相.

所以好多camera 公司研究 optical anti-shake 技術...... try to 露出少D their 弱的方面..... high NOISE...

so far only Fuji dare not to have their DC has optical anti-shake... their noise control is really good so far....

[wlachan]

Not exactly. Fuji achieve lower noise by applying aggressive noise reduction. It results in overprocessed pictures. Noise & resolution must be balanced properly to achieve optimal image quality. Their so-called anti-shake is just a marketing hype.

wlachan, 冇錯, 其實fuji點解比較low noise都係因為NR overprocess...


除左Fujifilm, 仲有Casio, Olympus, Samsung冇光學防震...

什麽是NR OVERPROCESS, 本人是FUJI用家，謝謝

OVERPROCESS???

有冇相睇睇比較o下?

[Banon]

唔記得講, 本人係Fuji F11用家.

For static night scene photos, there is no need to use high ISO. Using tripod with lower ISO will generally be better than high ISO.

For moving low light photos, you may:
- use high ISO to freeze action (but may result in higher noise as stated by iphilip)
- use flash (with combination of your choice of shutter speed) to freeze the moving subjects or show movement;
- use low ISO to blur the action;
- use low ISO and pan the camera for the movement

>>什?是NR OVERPROCESS

Noise reduction is a trade-off of noise vs details. Overprocessed NR photo will suffer severe loss of details -- however, it's a subjective issue IMHO. I don't want to comment if Fuji cameras over-process their noise. If you print your photos and they look fine to you, you don't need to worry about it.

Personally, I would clean noise myself so that I have more control of noise and details. Therefore support of RAW format is important for my selection of cameras. (Even if I shoot JPG, I will also shut off or set the noise reduction / sharpening etc. to low...)

影夜景緊係用低iso啦
不過如果想質素好都係用菲林機

[iphilip]

唔知DSLR會唔會有相反則不軌?

>>唔知DSLR會唔會有相反則不軌?

No.

[sofiakai]

原來我打錯左個 ' noise " wor .........

我都明明地高iso 既原理


唔該晒咁多位 ^^
