我想問晚上如在尖咀海旁影人應要怎樣setting?怎樣可以令到人同影都可以一樣..唔會一邊光一邊暗?

用腳架+後簾閃燈。

慢快門同步。

後簾閃做咩？

[fokkp]

負快門要後簾閃燈。

慢快門 / 快快門亦可用後簾閃燈。

我想問..400 d 有冇後廉的............

後簾閃燈唔係必須﹐無佢都得﹐可能仲好。

先要搵一個少受現場光o既地方﹐避開街燈﹐盡可能令背景比人物光。

之後﹐對背景測光。
如得出o既快門太慢﹐可以諗下加 iso 好﹐定係落腳。
加 iso﹐noise 自然多o的。
落腳唔怕手震﹐不過攝影對象係長時間曝光下可以會移位。
如無腳﹐可以加 iso﹐令快門唔慢到手震。
就係咁﹐背景就搞掂。

到個人﹐就靠閃燈。
只要人物係閃燈有效範圍內就搞掂。
如閃燈輸出唔太準﹐自己修正一下吧。

再 advanced o的﹐可以加 gel 紙改閃燈色溫﹐不過一步步o稷﹐先搞掂基本。


至於前/後簾﹐只係閃燈係剛開快門﹐定係剛關快門時啟示o既分別﹐對於一o的唔會走唔會跑o既主體﹐跟本一o的分別都無﹐對於夜景人像係毫無用處。
btw﹐你開o左佢﹐如非太長曝光時間﹐否則又無咩害o既。

快快門亦可用後簾閃燈？

咁有咩效果？

400 d 有冇後廉的...........

canon叫次簾同步。自己睇下說明書。不過可能無。

[micros]

影企定定o既人物就無分別﹐即係後簾係無作用﹐就算 400d 無都無所謂。
主體會行會走先會有分別:

(canon 都一樣﹐拎 nikon 做例子o者。)

You can try shooting in M-Mode,

first of all, take a picture in A-Mode, with Exposure compensation in +0.7 value, this will make your background appear in a desirable result, (pls choose appropriate metering method, as results will be very different, I would choose Averaged metering)

now check what Aperture and shutter speed you have for the good result you just shot, and change from A-mode to M-mode,

copy values of Aperture and Shutter speed, now take a shot in M-mode and you will see result that is the same as taking the above picture in A-mode,
now use flash (pop up or external) to fill light in for your model, (remember to use TTL flash for easy operations, M-mode flash will require constant adjustments when your model moves to a longer or shorter distance from you)

Remember this:
1) use shutter speed to control how bright your background is ( because your flash wont be able to fill light in for far objects in background anyway),
2) use flash to light up fore-ground, in this case your model, be mindful of distance between you and your model, as your pop up flash will need at least 5 feet to have good result, as you wont be able to adjust bounce flash,
2a) in case you use external flash, use flash compensation to adjust amount of light, less if model is very close, point flash away as well, test and see results, try to get a value and results that matches with your background,

if you are still confused, contact by e-mail. further explain to you

400D 有後廉同步.

不過 micros 既做法會有好d效果. 特別係加 gel 紙.

在低iso情況下.. 後廉同步還是會有快門慢主體矇既缺點存在.

想高iso又少noise? 50D / 5D MII 啦 XDDDD (暴走)
