到dpreview找了張lx3和ep1的藍天晴空照
ep1
LX3

實在是覺得片幅二倍大LX3的優點還未被充份表現...
ep1顆粒太大了

追加一張fuji天空的純淨度
f200

不知道問題出在哪？還是olympus對影像補正這件是還是新手？

E-P1 在 FNAC 體驗會上，olddo 說過 dpreview 的 E-P1 Sample 好像都是用 灰階 = 自動 拍攝的，所以才會出現低 ISO 的雜訊，我也覺得應該等上市後，更多的測試會比較正確。

原廠建議灰階設定值為 NORMAL 而非AUTO

好像所謂AUTO並非自動判別始否需要調整 而是幫您自動調整了
而設定Normal 才是需調整才調整

請參考 www.biofos.com for Olympus colletors & users

how to set up/customize your new camera

節錄如下
>NORMAL - No (or very little and/or subtle) effect on output.

>AUTO - As indicated the automatic application of slight exposure compensation to protect the highlights and gentle lifting of the shadows in processing. As with other E-System cameras with this facility, the E-620 result of the AUTO setting between base ISO and ISO400 is acceptable; over ISO400 leads to heightened noise in the shadow areas to the point where it is obvious and intrusive. At ISO800 for instance the results of the shadow noise generated by AUTO gradation become obtrusive. I'd recommend you use AUTO with care.

照這麼說來, Olympus 把預設值設 AUTO 不是自找麻煩 ? 隨便那個剛入 O 家的人拿預設值到餐廳室內調高 ISO 一照, 不被 ISO800 以上的雜訊嚇死才奇怪勒.

不過這也解釋了一件事, 常久以來我都把灰階設成 low or normal, 難過 ISO 1200 我都覺得還能接受, 而我朋友一直都百思不得其解, 原來是灰階的影響喔 ...
