點樣可以做到個景深深d.個景又清d?/

如果用f8+1/2+iso800拍出來都係吾清...

光圈再大d又會blur左.......


點樣先可以做到景深深d，同dc仔一樣呢？

hihi~
你都知...我都冇野可以教你= =
不過我想問...點解要用iso800ga?.?
dc同單反我諗都應該有落腳架...............................掛~.~

[intouch]

大家討論學到好多野…



我用iso800既原因係因為...吾夠光

f8+1/2

用f8.因為光圈細d.景深可以深d
用1/2秒快門.已經去到好儘.想光d..(.因為再快門慢，人會模湖左)

f8+1/2如果iso100根本就影吾清維港..(影風景時要f11+6秒左右先正常曝光)
所以一定要推高iso..iso800係我可接受既範圍所以就會做到

f8+1/2+iso800+閃

吾知甘樣推理岩吾岩.請指正



但做出來既效果.吾及我用f30 ...1/2秒+f2.8+iso400+閃,所以先想問下.維港幫人影相果d師兄係點幫人影既

[233062306]

我睇流左人像2個字............哈哈

如果係普通dc(我指唔係長炮果d)
就算2.8都唔會太blur...

如果人像正面冇光的話...
後廉閃佢應該就得...
1張相要10秒...個人係前面9.999陣都唔係好大影響...係閃果下就sharp~
當然唔會用10秒= =..我講下姐...
不過冇光射人像...用慢快門都ok...掛...
就好似用30秒影街...會影唔到d人...

如果有光正面射到人的話...我會放棄背景...開大個光圈= =...

我都唔係好識...等人打救我地吧啦...

i don't see whats the problem?

if you use flash and if its powerful enough, your model should have sufficient light to fix image on CCD

and then you can use 10 sec or even 20 sec for the background to exposure...

我哩張用400d 影... iso 200... F/8... 2S... 後廉閃... 係兩次閃之間盡量hold 住不動... 我覺得人同景都ok 清...

good example of 後廉
多謝指點

用dslr可以m mode, 2秒, f7左右該影到清維港, 之後企個主角埋去, 對好af之後即刻set去手動, 自己手持閃燈, 用10秒時間制, 聽到快門開左, 心算數一秒, 手動按閃燈test制

10秒內行去唔同位可控制埋閃燈角度, 如果係自拍, 唯有插機頂用後簾

聽到快門開左, 心算數一秒, 手動按閃燈test制

=====================================
咁其實係唔係人手版後簾 ?

kingkonghk:

幾好玩喎...! 不過我無外閃... 唔知搵第部dc 打燈得唔得呢...?

[kingkonghk]

>>咁其實係唔係人手版後簾 ?

係.. 不過好處係閃燈角度靈活好多, 唔駛直射, 燈多仲可以機身閃或機頂插一支, 左手右手各渣一支添, 好玩好多

"後廉閃佢應該就得..."

前廉: shutter開 -> 閃 ->影人->人震 (冇閃, 影唔淸) ->shutter關
後廉: shutter開 -> 人震 (冇閃, 影唔淸) ->(almost) shutter關-> 閃 ->影人> shutter關

我未try, but what is the difference to the 前廉 & 後廉 photos?

[233062306]

人震 (冇閃, 影唔淸)
==========================
我ga經驗有2個情況...
好似上面講...
如果冇光射到人像ga話...冇問題

不過如果有就...

hizaku,

For this type of photo,

1) first curtain, the flash will flash at the opening of the first curtain then usually people will consider the photo has been taken and move away, but in fact the exposure is still in progress (2s, in this case) so motion blur will appear for the people.

2) second curtain, the flash only flash at the closing of the second curtain and people normally won't move until they see the flash and consider the photo is taken, in this case the early exposure will not be affect as people will not move. When the flash light the photo is completed and motion blur can be avoided.

For taking car with light trail the second curtain flash will make the light trail after the car otherwise the light trail will be in front of the car.

我這張用機仔影, ISO400, F/32., 快門1/15, 後廉同步閃燈.
