想問下如果用 slr o既 b 制如果曝光時間太長...係咪都會好似 dc b 制咁爆晒架???

人地 b 到 30 秒o個d其實對我黎講真係好神秘.....

仲有就係 slr 個 iso (25 - 1600) 多數會點用??? dc 我就永遠都係 100...但係 slr 應該點玩先好呢??? 係咪菲林係 200 就 200, 400 就 400 咁架.....如果我想玩到油畫咁o既效果 (粗微粒)...係咪應該去到 1600 呀???

有勞有勞......

用b門唔代表會爆, 爆光係因為過曝, 同你用SLR定DC冇關係.......
同埋冇話幾多粆快門就一定會爆光, 完全係睇環境.....

用SLR, 正常就跟筒菲林黎set ISO, 當然想玩效果可以調高或調低iso值, 再係沖片是配合便可....

要粗微粒, 可以選用ISO較高的菲林, 如800或1600, 或者將低iso值既菲林迫沖都可以.....

印象中,淨係正片先可以迫沖,負片唔得.

傳統沖晒負片也可迫沖，
數碼沖晒機就無得迫沖(機器無得SET)，

上次去一間傳統沖晒店，女沖晒員問返我轉頭：「迫沖，咩0黎0架？」

DC 用 PS tune 光佢羅.

有時去 d 細間的晒相鋪.. 連 slide 都唔知係物. >_<

[smartlam]

通常我叫(迫沖)係(谷沖)多。而家好多沖印店請好多後生仔女,佢地都係冇咩經驗0既! 我試過好多次拎菲林去沖 4P 全景相片 , 講左好耐幾個店員完全唔知我講咩! 要射印緊0既老細起身招呼我先掂。我仲遇過有 d 我問鏡後柔焦0既價錢,竟然冇人話知係咩! 吹脹~

"人地 b 到 30 秒o個d其實對我黎講真係好神秘....."

菲林相機同DC 光圈的分別
好多時菲林機的光圈都可以收到去F22 F32
而DC 就多數係F8
在同一情況之下菲林機用B 快門時曝光時間可以比DC曝光時間更長

sorry 呀，我係新手o黎o架，我都知咩係鏡後柔焦同迫沖呀，可以話我知嗎?
同埋我想問邊度有講多o的攝影o既名詞同技巧，因為冇睇呢個post都唔知有o的咁o既野，我好想學多o的呢o的，可以話我知嗎?
thank you !^^

唔該晒....其實我係應該自己試下影先o既...不過又唔想亂咁試浪費菲林...有勞有勞....

[south_south]

nereid1229 :

點都要試下，菲林尼D 野慳唔到
試過後知道發生問題，下次改善就唔會再犯，咁試驗的菲林就會值回票價呢

買D 平D 的菲林試 ^.^

咁係咪好似 dc 咁...用 100 菲林黎 b 係好 d 架??? 睇過呢度 d forum 話 dc 用 iso 100 黎長時間曝光係會靚仔 d 架麻...??? 好似話 iso 越細越好架麻...

咁 135 黎講係咪都係咁架?? 我用 100 菲林但係 set 個 iso 去 25 會點呢???又或者去到 iso 1600 可唔可以做到油畫咁o既效果呢??? 其實我個人黎講唔係咁想加後期制作...即係晒相先"逼沖"...假設菲林有生命...咁逼佢法真係冇乜幸福喎....

我都開始覺得我真係好多問題...其實我真係會去試...不過想有個心理準備先...心急麻....有勞有勞.....

nereid1229:

ISO 值就係菲林的敏感度...
通常越低的ISO 值敏感度越低，但微粒會幼D
而高ISO 的菲林則相反

而DC 用低ISO 因為可以令雜訊無咁多

如果你將100菲林 格硬set 到去 iso 25
出來的相就會over幾級
基本上你用甚麼菲林就要set 番好正確的ISO值俾相機知
唔係數碼機話set 就set


但多數依家相鋪都經過電腦先再出相紙，同埋會有一順手幫你執一執(如果D 相 Under or Over)
小弟識的野有限...有錯請指導下我

When you're doing long exposures with Film(regardless of -ve/+ve) , you should beware of the reciprocity failure , please refer to the film you use.

(to nereid1229)
If you wanna do push processing , most probably you should inform the guys to push the film to a certain level. However the pushing ability varies from film to film. For instance , Kodak claims that their TMAX400 can be pushed to EI1600(2 extra stops) while P3200TMAX can be pushed to EI25000(3 extra stops).

About printing...uh , I'm not sure whether you can "push" underexposed film image on printing paper , nevertheless it looks like printing papers(and well , so do films? not sure again) DO have a significant level of exposure error tolerance.

About Digital , hmm..... A low ISO setting could surely use a longer exposure time in contrast to that of a higher ISO setting. However in my opinion , a marvellous night scene does not necessarily involve using a low ISO sensitivity.

If you wanna do painting effects , the current issue of "photo magazine" has a short article about it. It's all about multiple exposures.

ahhh I've forgotten something , I'm a newbie , plx flame my mistakes :P
