機身:閃光燈同步,1/125 非原廠外閃指數:32
請問於日間拍攝人像,用外閃作為補光時,該怎樣做呢?
(1)光圈先決:選定光圈,其它交給相機處理.
(2)快門先決:設定快門1/125或更低,其它交給相機處理.
(3)全手動:快門設為1/60,用閃光燈指數除以主體距離,得出的數,作為光圈值.
(晚上是用這方法的,但日間行得通嗎?)
(4)全自動:全交給相機處理.
另:景深處理方面,跟唔用外閃補光有沒有分別呢?
(大光圈,快門高過1/250,能起到補光的作用嗎?)
請多多賜教,謝謝.

你支閃有無auto mode?其實係邊支黎?邊部相機?

[tonytony709]

先謝過回應.
我有三枝閃光燈:
1:TUMAX 320TFZ
2:MINOLTA AUTO 220X
3:MINOLTA PROGRAM 3200i
機身是KM D5D
(但恕我唐突;這設定跟甚麼型號有關嗎?)
後輩唔識野,莫怪.
誠意求教.請多指點.

知用乜器材就可對證下虊,呵呵!

以我所知D5D個閃光燈有效快門最快唔只1/60s,基本1/125s,起碼1/160s都得,呢一點好重要,因為日頭用閃光燈,有效快門越快越好(又係值錢之處).

假設你唔用飛燈( at hotshoe TTL),我會用快門先決測環境光,可能得出iso100,1/160s,f8,之後咪相機用m-mode lock死,對焦,夠掂.

假設你用閃光燈auto mode,咪測光之後用,閃光燈set iso100 f8(假設),對焦,夠掂.

假設你用閃光燈m-mode,測光後對一對閃光燈輸出表(如果無,o向屋企用電腦自己做返個,唔洗下下即時計,好有用,尤其是玩飛燈),閃光燈set iso100 f8(假設),對焦,夠掂.

如果玩飛燈,買返個測光表會好好多.

謝過指點.
話說在前:唔好嬲.
(1)KM D5D HOT SHOE是用CDI既.如想用TTL就要加轉接座.(到時會唔會甚 麼功能都失效呢?)
(2)如果小弟有測光錶的話,就唔會出呢個話題啦.(我會出"各位對東芝的測光表有甚麼評價呢?)
最後,衷心的,誠意的感謝回應.再三地.

o我!最主要問題係,你對你自己o既器材認識了.一般情況都分享過,你自己執生吧!

可能有過來人同你器材及情況差唔多會幫到你呢!

[tonytony709]

係喎:好似好少見到師兄們提及有關測光錶的事喎.
以前就講求甚麼入射式.......
唔知現在進步到點呢?

tonytony709, I am using A100, similar to D5D

your 機身 D5D:閃光燈同步,1/125 非原廠外閃指數:32

ASSUMING ISO 100, GN = f no. * distance in meter
============================================
(1)光圈先決:選定光圈,其它交給相機處理. <==== your shutter speed MUST no exceed 1/125 or 1/160!!!!

which mean YOU HAVE TO ADJECT THE CAMERA TO OBJECT DISTANCE FOR PROPER EXPOSURE!

If the GN 32, for sunny days, u set 1/125, f should be 11 or 16, your object is backlighted, if u want your object proper exposed, your object should be at 2 to 3 m, if your object is also lighted by scattered light, then your object should be 3 to 4 m.

for slightly cloudy days, u set 1/125, f should be 4 to 5.6 & your object is NOT backlighted, if u want your object proper exposed, your object should be at 6 to 8 m => U MUST HAVE A TELEPHOTO LENS

OR u use a tissue paper to cover the flash, then the effective distance should be 2 to 3 m (my experience)

(2)快門先決:設定快門1/125或更低,其它交給相機處理.
similar to (1)
============================================
(3)全手動:快門設為1/60,用閃光燈指數除以主體距離,得出的數,作為光圈值.
(晚上是用這方法的,但日間行得通嗎?)

YES, but SUNNY days, if the f no. is very high, e.g. 16 or 22, your camera to object distance should be 1.5 to 2m
============================================
(4)全自動:全交給相機處理.
另:景深處理方面,跟唔用外閃補光有沒有分別呢?
(大光圈,快門高過1/250,能起到補光的作用嗎?)
NO!!!!!
============================================
I guess u better look for a 2nd hand 3600HS flash to minimize your trouble

回應收到.
謝謝.Obi-Wan.

建議熄左個防震,快門可以去到1/160s,有小小幫助的.

[tonytony709]

誠意感謝各位師兄的指導,令小弟穫益良多.謝謝.

[thaishan]

我的是fz50 閃燈是銀燕全手動
我先選用光圈先決,再参考閃光燈指數做光圈數,
再移動相機到背景位,再按AE-Lock,
再移動相機到正常位置.....

[six_seven]

係!prosumer 機有呢個好處,無段閃光燈有效快門,閃光燈快門去到1/2000s都無問題,DSLR or slr 就有呢個包袱了!

[lmichael]

測光,以前係好重要,因為菲林,唔曬出來,都唔知會點,用閃燈就最易出事,但係現在,數碼機影人像,就簡單好多,我都係用緊手動閃燈,睇完閃燈光圈表,再影兩張,睇睇效果,好快得得到滿意效果,所以現在用數碼的人,都好少帶測光錶.

樓主都係帶番架計數機好D
