雖然小弟都係反對做大量的後期制作的人.不過成日都有一個問題想同大家研究研究.
之前好多師兄講, nikkor鏡好利好sharp, canon 鏡柔加上body的coms 都係比較柔, 加起來就柔上加柔. 之後我又唸, ps/acdsee內有一個sharpness可以推高sharpness, 這樣咪可以解決c記遍柔的問題. (不過有師兄說這樣做會增加noise, 不過c記機出名少noise, 所以推高sharpness, noise都不太明顯) 小弟亦試過在ps推高sharpness, 不過就覺得推高sharpness張相好假, 是否直接由鏡頭造出來的"利"是無辨法在後期制作所能造成?

can you post D photo see see

[ahkei]

software's sharpen method will lose some contrast and creat some noise

Ah~
make sth blur and sth sharp~
which one u think is easier...?

[kkyy]

Please be reminded that make something blur by software =/= a soft image that has not been sharpened by your camera.

A soft image is meant to retain details while a "blur" image is not, and it lets the photographer to perform his/her own style of sharpening. If you want the camera to do it for you, then you can adjust the camera setting accordingly.

其實在大眾攝影2005 No3 的P65 有提到數碼相機的處理器因要處理不同信息引至很多時不能達到最佳狀態，甚至是"虛"的，所以數字影像有再改善的空間。各種品牌的數碼相機都有自己配套的圖像軟件，就是為了彌補和廷伸數字圖像處理器的不足...

可以咁講, PS可以彌補和廷伸數字圖像處理器的不足(如sharpness) ，有效發揮鏡頭的sharpness, 但過火(超出數字極限)會變得數碼(假)

[geofku]

鏡頭的"利"是指它的成像能力。當影像被Capture之後、用後期修整只可以糾正小部分的defect而矣。舉例、你拍人像時、如果有良好的成像、人物的髮絲都清楚可見；但如果你拍了一張唔sharp的照片、你能夠用PS把髮絲重現出來嗎？Sharpening只可以把幫助視覺上銳化一?、過分的銳化不單於事無保更曾加noise。你可以用PS把髮絲一條一條的重新加上、但這樣一來非常費時、二來影像的?實性已經失去了。希望可以答到你的問題！

多謝各師兄指導

之前上過Canon有關DSLR的課程, 導師對350D的參數設定有以下官方建議 :

On-Camera : Contacts -1; Sharpness -2; Saturation +1; Color 0
On Photoshop : Amount 400%, Radius 0.3 & Threshold : Portrait 3-4; Landscape 1-2

Result looks much better than plain setting

[kanji]

C記機已經好柔, 如果SHARPNESS SET -2. 咁咪柔上加柔???

[nm168]

咁, 請問各師兄知不知道 20D 的官方建議的參數設定 ?

[sunnylauhk]

kanji,

The reason is to leave Photoshop to do 100% sharpening job.

[tommywhite03]

小弟以往都係用Photoshop由RAW轉JEPG相，
後來發覺用Photoshop出o既相成像有D問題，
於事有Canon o既Digital Photo Professional 作比較，
竟然有如此發現，
所以小弟再無用Photoshop了。

100% Crop 冇加後期
Photoshop CS

Digital Photo Professional
