師兄

附失敗照片1張，請指教下面 2個 問題：

1. 用 wide鏡 影相時，時常天一半，地一半，上/下 曝光可能相差要1.5 級，
以我呢張相嘅情況，如果我假設上半OK (因我喜歡那個星茫 及 氣氛)
咁我點樣做可以另下半部額外多1.5級補光？

2. 又假如前面企個人，咁係咪要用閃燈壓光？
但閃燈高速同步快門只得1/250，咁個背景豈不是會過度曝光？

此照片於正午約4時影，光圈 F/13，快門 1/4000，ISO 100



請師兄教路！

Thanks !!!!

1) you need a graduated ND filter (e.g. Cokin / Lee)
2) you need an external flash with FP flash function (high speed sync)

[nw1]

師兄

1) graduated ND filter = 漸變 filter 嗎？
其實我都有聽過 漸變藍 filter，但有無平靚正介紹？

2) FP flash 是什麼？430EXII有無？

Thanks !!!

nw1 大大,

1) 可以試用鴨記貨...

[rankinelo]

1) graduated ND filter = 漸變 filter <- yes. I use Cokin one since it is cheap. Lee one is better but much more expensive. Many of my scenary photos in my dcfever album uses Cokin filter. If you think that it is acceptable then you can go for it

2) 430EXII有無 <- yes of cox. it is in the mode "H". Please read the manual fo 430 EXII.

Hope that it helps

rankinelo 兄

Thanks for the information. It's very useful.

For the question 2
Does the camera need to support the FP flash too? How about the 60D?

Furthermore, if there has FP flash function,
why we say the 閃燈高速同步 is 1/250?

Thanks again !!!

[rankinelo]

nw1 CHing,

>>camera need to support the FP flash
almost all EOS camera (in the market now) supports FP flash, so you need not worry. When the FP mode in the flash is on, 60D supports this function automatically.

>>why we say the 閃燈高速同步 is 1/250?
This is a technical problem. to make it simple,
閃"一下"的話, 快門最快的速度係1/250... bottleneck係機身
但係其實for閃燈, 閃"一下"出現的時間係大約1/10000... 所以如果佢"係咁閃", 就算快門唔係全開, 拼番埋的相都係一樣光

再唔明請google一下

你試下用HDR
即影幾張相同合成或用raw做
不過我試過, 有時出來的感覺係怪怪地, 可能我ev +-得太多, 始終唔太自然

rankinelo 兄

哈哈！一陳約咗位師兄交收 430EXII，到時就有manual 睇！

咁即係唔駛理 1/250 呢個問題啦！

另你話 <<<閃"一下"出現的時間係大約1/10000... 所以如果佢"係咁閃">>>
咁 580EXII 個 multi flash 係咪又是另一樣嘢？
字眼上咁相似嘅？

Thanks !!!

What camera u use? if your camera has FEL it will much better

[rankinelo]

"multi flash" is another function

e.g.
580 可以set 1秒內閃4次, 但係4次都係快門全開間的事,
通常玩一張相有幾個影用.

FP flash係快門不能全開時, 係咁閃令到成張相都有flash light, 係破解max XSync speed的方法

[nw1]

wolfwolf3D 兄

I am using 60D for 6 days only.
Does FEL can only use one fixed 曝光設定 for a whole photo?
could not have upper part with less exposure than the lower part?

Please correct if I am wrong !!

[nw1]

Thanks all 師兄

你地幫我破解了個大迷團！

[nw1]

呀！師兄！

還有一個問題，
咁閃燈點解唔長著 "H" mode？

Thanks

[怪俠]

ps 唸會唔會好d？試試先..
