The simpliest method is to meter off the orange sky near but excluding the Sun. Use spot or centre-weighted meter and slides. However, everything else might appear dark so beware. |

Peolle always ask why need to learn the Zone System ...... here is the answer.
The answer is ...... spot meter + Zone System + bracketing exposure. |

wlachan提議既方法已經好夠用.
ps:得閒就睇多句~~"一般反射式測光錶是以18%的灰調作為曝光的標準".

spot meter好蝦人用, 唔識用就好易「香晒」.....
我用平均測光, 因為日落不單止是紅雲, 仲有好多前景、中景、遠景同埋太陽...
人眼都係平均測光o家.....嘻嘻...

不同光度的相片有不同味道－－一句講晒：bracket啦！
BTW, zone system同bracketing似乎是對立的啊。 |

如果天空同下面既曝光時間差太多
可以試下用黑卡+重曝~~

彩色Zone system 定 黑白ZS 先? 彩色要實踐, 會..... haha~~~ Adams 過左身啦喎, 同埋點計D max 同 D min 先 RGB grains / color film (我指家用或小型用), 再自己放大計算出黎? Zone system 不單是film exposure 啊 ^_^~~ ----------------------- BTW, spot meter is good method, 加上用多某種film, 了解其特性, 可用經驗"大慨"知道film exposure 級數, (eg, some normal film is between 5 stops, over/under 5 stops, not good expose) ^_^ http://www.paulkcy.com/sunset05.jpg |

>haha~~~ Adams 過左身啦喎,
即使他未過世，看見新一代攝影人用tone curve用得出神入化，睇怕會非常無癮。 |

I think bracketing is good as a fail-safe backup for slides (say 1 or 2 extra exposures +/- either way), but hardly the solution. It is kind of silly to bracket like crazy when the photographer had no idea what he was doing or what the approximate correct exposure setting was. Even with digital, the time spent on choosing and deleting useless exposures afterward in the field is tiresome. |

如果無Zone System既概念, 點用spot meter測光? 起碼都要明白Place and Fall ......
我同意彩色係要經驗, 但我用得好好!
kcy_kwok兄, "The Negative" 本書入面已經提到點樣應用Zone System o係Color Slide度!
Peter Lo兄, 我用Curves就真係出神入化左10年8年, 皆因讀過Sensitometry, 概念讀左唔會哂既,
智識係自己既 ......
我唔係Ansel Adams既信徒, 我只係應用我讀書讀返黎既Sensitometry同Zone System既概念,
用Zone System既概念去影相都咁多人唔滿意? 世界變 ......
乜呢度好多人好憎Ansel Adams? 我唔識佢個喎!
我主要係讀Sensitometry, 順便睇埋Zone System咋喎 ...... |

Color slide涉及黑白顯影，當然可用zone system。
咁煩，讓我選擇的話，我都係選用tone curve。 |

agree with wlachan again.
I think that 日落 is too contrasty
to use bracketing effectively without
choosing an appropriate point for metering FIRST,
whether you use spot or CW.
Reading with and without the sun being measured
can give a 4~7EV difference. How many bracketing shots
are enough to cover that large range? I need over 20~30 brackets
to cover with 1/4EV per step.
Back to basic (principle of exposure) and keep it simple and stupid (KISS):
choose a mid-tone area (without sun) for metering is the first step.
then, use bracketing if you like. Personally, I do not use braketing even with slide. If you really want to take the challenge, after taking the reading ask yourself " to what extend the area that I used for measuring EV match 18% grey?" and "whether I want to keep the picture a bit darker to retain the atmosphere?". If an overly bright area is used for metering, add some ev (why?). If an overly dark area is used, minus the ev a bit (how much?). 18%gray is an important criteria for helping you judge and use the reading effectively. If you make the appropriate judegement and adjustment, a single shot is enough even with slide. |

嘻...Peter....
讓我選擇的話，我都係選用photoshop 既 curve 算數啦 (^_^) 笑~
Cloudy君~
唔駛勞氣, 其實無人質疑你既諗法.
只是大家講出自己心得同疑問~~
開開心心討論嘛 ^_^ |

---------
why without the sun?
(1) the sun is too contrasty, much more brighter than the environment.
(2) camera light meter is reflectance meter, it assumes that the reflectance of normal things as 18%. It works fine when things are within 10~25% reflectance. If you use a reflectance meter with the sun included, you are using a "reflectant" meter to measure "incidence" light! You got wrong readings. That"s why "superman" mentions that it is not appropriate to use such metering in the link listed above.

其實點解我唔教 Anthony18 點測日落呢?
係因為佢既描述其實無乜幫助, 日落難既地方唔係用邊種反射式測光錶 (不過一定要反射式), 或者測邊個位, 而係:
1. Local (Subject) Contrast 每次都唔同 (e.g. 有霧無霧都唔同)
2. 我地影日落唔係做reproduction, 而係要影出氣氛
所以, 實踐同bracketing係一定要既 ...... 我知超人兄之前o係第2條thread都提過類似既野, 不過我都補充一下!
P.S. Arthur塗夫, 我都信你可以唔bracketing (因為有左經驗的確可以), 我上面果D野係寫俾其他人睇, 唔係唔信你! |

冇所謂,用咩方法都好,影到想要既野最緊要.
人人風格唔同,我鍾意慢慢來,一擊即中個感覺. |

re: Cloudy
When someone asked for a quick and simple solution, I offered one. Your opinions are contructive and useful though we have different shooting styles. Some people love bracketing, some don"t, but I can see no critism towards you so far, so just enjoy the discussion peacefully. :-) |
