Hello Ching,

請教為何用5 D Mark II 拍 Jpeg + Raw 的相片,

很明顯 Jpeg 的相比較明亮,可以不用去執相都得,

但 Raw 的相就明顯比較暗,要用軟件去處理. 才比較好些

請問是否正常或是部相機有問題

同時影 Raw 的相,是否一定要執?

This is my first time to take raw photos, so...........

Tks

JPEG係已經被處理的相，相機會有所調整
RAW係直出，完全係原始影像

[聖戰熊]

正常情況，部機無問題。
RAW 檔無不加任何修飾嘅原始資料，
如果唔想執相，用 jpg 就夠晒。

All Ching,

Tks for the informations & understood

我也有類似問題，那是否用raw影完後轉jpeg,質數與影jpeg直出一樣呢? Thanks!

[dichomate7]

唔係。
搞清楚先，JPEG係一種格式，唔係一個專有名詞

相機影左張相之後，會自動調整相片
出黎ge制成品就係一張以JPEG作格式的相
而相機影完出黎而未經"執相"的相片就係RAW

如果將RAW人手convert做JPEG格式，張相就會同RAW一樣

RAW 係原始DATA, 佢唔係一張相, 要經轉換軟件如最簡單既DPP 套用各種參數後輸出成各種電腦可以直接觀看既圖像格式. 在此你可以隨意調整基本設定如光暗(當然仍然有限度但比JPEG 大得多), 色溫, 色飽對比等. 而唔會損害個RAW圖檔

簡單如一張UNDER相, RAW推光2級暗部保留到既細節已經同一張由機身JPEG唔一樣, 更甚用PS 作大幅調整, RAW 都可以保留最自然順滑既層次過渡, 但JPEG 做相同動作就會出現顏色斷層. 影RAW 可以任你自由創作想要既效果作無限調整無限輸出而唔會損害RAW 本身存有既資料. JPEG 則只有機身直接輸出成圖檔方便作即時沖洗或上傳, 分享, 觀看之用, 或唔願執相既人使用.

想理解多D 可以去睇下D 入門攝影書或上網搜尋.

仲有, 數碼世界裏好難界定直唔直出, 就算影JPEG 都可以事前用各種PICTURE STYLES 再作細部微調, 就算唔郁D 設定,
相機每個PICTURE STYLE 事前同你拉過CURVE 輸出黎既一張相, 仲認為佢叫直出? 比你搵到架機真正直出既相, 張相都嚇死你.

besides the technical difference of Raw and Jpeg. user will find the biggest difference is MORE TIME in dealing with RAW.
converting, editing, post processing........ part of the RAW.
yes, I use RAW always with 7D. Yes,
I normally will not post process every photo. I snapped a lot, then delete a lot and only pick 3 to 4 better photos ( among around 100) and use RAW and photoshop to edit it. then Jpeg to friends or web.

Defniitely, RAW give me the best option; I never worry about wrong white balance again!!
especially with photoshop, you can do anything as far as you have time.

so, don't think that photsohop is only commercial photographer can afford or need it. Comparing with the high price of a L lens, what photoshop give you is worth many times of the penny. 用得盡,就超值!!

thanks siusun ching, but still a bit confuse.

leesunghojason ching, based on your explanation, may I further ask :

If I set picture style 'vivid', use RAW, then output in RAW, is the photo still have 'vivid' picture style?

Thanks
