a700高ISO小秘技

ahshing

我諗咁樣既質素，唔好話縮圖擺上網，直出曬大相都應該冇乜問題

Click小圖可看大圖

a700 v4,Helios 44M-4
ISO3200


ISO6400


放大圖時，記得留意HI-C個C字下面既水珠...

秘技就係...
ISO NR:High
DR+
Creative style: Standard,Saturation+1,Sharpness+1,Brightness-2,Zone-1
另外最好用返Standard同Neutral既Creative style，sharpness既調整都會影響到noise明唔明顯，用+1就o岩o岩好

The details are all gone in ISO6400.

ISO3200 is still acceptable.

noise is removed as well as the detail...
can obviously see NR is done on it...
one more thing... if the photo is bright, the noise is not that obvious...
please try to shoot something at night and try again. Thanks!

我比較懶,如果唔係,機身NR off,然後放落電腦noise ninja一下,效果一樣好

我諗a700咁既質素,同D300,50D比,已經相當稱職

唔講咁遠,就用D300黎比,所謂detail lost,係事實?還是偏見?

我呢度既現場環鏡一d都唔光,只係我加左曝光補償
低光攝影,都唔係完全冇光源走去影丫
黑媽媽光線唔靚既相,俾我覺得唔影也擺
如果你話低光試鏡+聞相,我係有做過,不過我覺得平時冇咁既必要咯...

a700 v4 / sigma 15-30 / 手持 / 防手震 on / 12mp xfine jpg / 原相resize後直出
除#2指明nr off外，其他都係nr low
如果用raw轉jpg相信質素更高

i was talking about the area of low light in the picture would show the noise more obviously
what i mean is that if you shoot one with lower ev value... to retain the mood of darkness, say, in a pub, i don't think you shoot so bright, right?... you will see how horrible the noise is... i am not just talking about sony/km but also other system...
noise is more obvious in low light part...
