你講得都很對,唯獨.....樓主那種調性,應該是日本比較常用的,歐美對比不是更強烈嗎?

最後,我還是強調,色階圖沒在看什麼DR值的~真是誤導~我們是在拍照,從事影像創作,更不是做數學題~拜託!!
至於powerslide大師的言論,是他的自由,我只是覺得,身為技職人員或得獎大師,說話論述,還是低調和緩些,畢竟~要有眾人的欣賞,才能成就我們的工作及創作口碑~
P.s得獎是榮譽與肯定,但不是拿來批判別人的工具~

又一個自曝其短的

麻煩您,把以下紅色標示的文字看清楚再來斬釘截鐵地說色階圖沒在看什麼DR的

(你以為gamma值是幹什麼用的)


"Dynamic Range and Bit-Depth

Converting a high-quality scan into an 8-bit linear (gamma=1.0) space value would truncate the dynamic range, since it is physically impossible to store more than DMax 2.4 in an 8-bit integer. However after using gamma encoding it is theoretically possible to store a dynamic range of (log(255^2.2))=5.30. In reality the "sparse" data in the lower extreme of
any 8-bit non-linear (gamma encoded) space considerably limits it's useful range.


那個數學公式就是在證明此點

糾正一下powerslide誤導入門者的謬誤~歹勢
看色階圖是參考依據~不是絕對~
它是用來判斷一張照片的階調在什麼位置有多少的色素在其中罷了!
從業十多年來,階調的分佈會依拍攝環境條件而有所不同~
如果一昧的要求準確分佈反而是種"病態"~
色階表的功能是在紀錄0~255階中,相機所記錄的RGB光量的多寡,所以在photo中,分別為RGB及R,G,B四種不同的色譜!
如果照powerslide大師的說法,會有很大的誤導~


噗哈哈哈

也麻煩您去糾正一下這個阿朵啊的說法吧

他的說明可是大大地打了您一巴掌



This histogram shows an almost perfect distribution of tones covering about a 4 stop dynamic range — from deep shadows on the left to just short of bright highlights on the right. This fits comfortably within the approximately 5 stop dynamic range capability of most digital imaging chips.

What Histogram shows


Histogram can tell you many things about the image, about the processing already done on the image and also about the device (digital camera, scanner ...etc). First look at the x axis. This represent the dynamic range 0-255 (dark-light). The wider is the histogram , the better is the dynamic range and that means also image with better contrast.


















Dull Image 







 


Narrow histogram - small dynamic range means low contrast and
flat image





Normal Image 






 


Wide histogram, great dynamic range means also good contrast

powerslide大師~真是名符其實的硬體狂~到底是拍照還是算數的啊~要比劍,就亮出你的作品給大家瞧瞧~拿黑時期的階調曲線出來論述~會不會洗黑白啊!!
看國外數據,數學公式,重點是你到底拍了些什麼東東,指正別人的謬誤,請用眾人看得懂的論述方式~~得獎又怎樣~不會做人,來商界比比~看你怎麼活!!
藝術本無罪,就你這種人不進步~枉害後進不知路~~前輩不是這樣搞的,你知要眾人服,人不服你枉為師,學著點!!

噗哈哈哈哈
要秀照片是吧
我已經很久沒秀照片了
只怕我一秀出來就讓您下不了台啊

對付您這種程度
我肯用技術資料跟您談已經算很禮遇您了
還不乖乖地多學點技術
談什麼藝術,您還不夠格呢!!!!

(國外的技術資料多讀讀,不要只逛國內的網站,這才叫長進,懂嗎?)

哈~終於有圖了~
來來來~~大伙別客氣,評一下大師的"藝術創作"吧!!!

咦?

不是接下來閣下要秀圖嗎?

從業十多年,該不會連件像樣的作品都沒有吧!

不是您要图的嗎?
怎麽自己不先奌評?

哈~轉檔中~小弟是拍商的!稍等一下~~
好精彩喔,期待期待。兩位大大應該都是超級強手:)
