各位師兄, 我試過用兩部 DC影同一magic hour, 結果如下:
DC(1) ccd size 1/1.6", 用f2.8, 1" 已經好夠光, 影出來好靚,
DC(2) ccd size 1/1.7", 用f7.1, 15"影, 出來好暗, 唔靚

請問點解差咁遠呢?咁我應該用邊個作準呢?

假使同iso, 請問digital機測光同菲林機測光係咪好唔同?.

ｉｓｏ是電子模擬飛林感光，每部相機不盡相同，不過都是聽講，５知對不對

＞＞＞DC(2) ccd size 1/1.7", 用f7.1, 15"影, 出來好暗, 唔靚

請問是甚麽相機，爆光１５秒應該好多ｎｏｉｓｅ

should be the same.

it's should be nothing to do with ccd size, iso, aperture or whatsoever
after all, there is only one formula for such calculation

there are too many ways that can cause your problem; but it's up to you who decide how to remedy

for example, diff setting of exposure metering, like multi or centre can give a huge difference: multi will look at the whole/larger area for 測光 while centre will just look at centre

and it's a photographer's experience that when shooting Bright object just as sunset/snow field, you should +2 or +1 EV, while shooting at dark object you should make it -1 or 2 EV, see what effect you want

it's because camera is always right, making it 12% grey, and as a result, bright objects tend to underexposed while dark objects would overexposed, that's why the need of EV adjustment

Nailimixam,
同樣環境, 同樣影法, 但分別就好大

oly750,
15' 多noise都冇辦法, 問題係唔夠光.

d2c,
係呀, 我都試過, 分別好大, 點解呢?

我而家諗緊到底係DC(1) 定係DC(2) 比較準

[Nailimixam]

I think you focus on the wrong problem...

For me if you using DC1 then use the DC1's way to take pic, DC2 then use the DC2's way

anyway, just check if your exposure meter setting is the same for both DC

and see if you are using the same ISO. don't need to tell you that auto ISO will keep changing i guess...

2.8同7.1都差左幾級光圈, 1秒同15秒都係差左幾級快門, 當打和囉

唔同牌測光取向有出生入, iso定義都有出生入, 睇最終結果好d

just curious, so.....it's pointless to use a light meter on DC? coz the result can't be use like the film camera?

by whose definition.....

by definition 88th floor should be counted from G/F to 87/F...

唔好講DC. 正片同負片, 同1牌子, ISO100都有出入
