問題係正本無咁既精度, 又點樣出一張咁既解像既副本. 要留意, 4000dpi 係未經處理前既實際解像. 如果經PS 真係可以張實際解像提高, 4000dpi 既scanner 都一樣係多餘, 用2400dpi 再插值處理咪得囉. 其實PS 比你睇到唔你好左, 只係更加合人既眼緣組.

There are 2 issues here. Film resolution, and scanned quality. Some said 5000dpi is the max resolution of film, I don't know. But it takes some very high end drum scans to pull the true details from films. The consumer scanners that we are using are no where near that quality, not even the most expensive Nikon. However, I had a 20x30" traditional print done by a professional lab in Australia many years ago. The film was Kodak Gold 200. The print shows good detail, but grain is a problem.

The idea of resampling is to increase the print size, not the details. |

How about dynamic range?
I don't think any DC/Scanner have a dynamic range near to the cheapest slides, not mentioning the extreme case of Kodachrome.
Moreover, how about color depth? |

問題係菲林同鏡頭既解像極限, 24Mp scan 出來當然唔可以同24Mp 既DSLR 影出來比, 因為係scanner 係 copy 菲林出來的. DSLR 係影實物. 如果真係要比較到, 菲林既解像起碼要係scanner 既兩至三倍先可能有相似效果, 另外CCD/CMOS 距離24Mp 仲有很大, 另外有好多菲林比KODAK GOLD 200 更幼細的. 而且正片就比負片更要好上許多.
另外 24Mp DSLR, 24Mp 係已經插值後既解像, 只可以做一次, 再做個grain 一樣唔得.

菲林 vs DC/DSLR 基本上是 film scanner Vs sensor
都是 digital vs digital
CCD/CMOS 技術不斷改進, 同樣 film scanner 及菲林也在進步
暫時仍然是互相角力中 (先別談那一方現在較佔優)
我想最重要一點是廠商的方針, 只有他們一天還未放棄菲林/scanner, 這課題依然是沒完沒了
別忘了廠商廠商是向錢看的, 當大部人都重視 DC/DSLR, 投放在研發的資源只會愈來愈多 |

"傳統攝影"及"數碼攝影"兩個terms根本就有問題.
攝影是一連串影像製作及重現程序,隨著科技進步
和普及,攝影這個set漸漸被拓大(span).給製作者
及受者多點選擇，提昇效率.民用相機加了Sensor
成為DC只是extend了攝影的領域,不必是用來取締
前者,兩者不能互相取代是也. 如果有部相機同時
具備兩者功能,這不是取代底片相機,是跟它合併！
盲拳要打死老師傅要睇condition,如果鬥測光,
傻瓜拿著AE機遲早會打死用人肉測光o既老手,皆因
人有好多限制,但AE永遠有改良空間. 說穿了就是
電子技術簡化了從前煩瑣的工作,突破人o既限制.

我仲未明打乜? 攝影又變成人與人爭鬥的工具.....!
影相變成做生意就唔同, 幾大都要打贏!

問題是DC甚麼時候會取代傳統SLR? |

quote:
sinar已經有22mpix機背, 24mpix指日可待....
sinar 出的是中片幅機背,
比135 大很多,
要出到24mpix 當然指日可待,
但要135size 出到22mpix,
相信都要一段時間. |

I think the question in discussion is off track ....
First of all, - 問題是DC甚麼時候會取代傳統SLR - Even DC can be SLR as in EOS 10D etc.... SLR is a technology of the viewing system, not the media, whenever there's a need for this technology in the setup, the SLR will still be implemented ( eg. Macro, Landscape etc..... )
As to whether Digital will replace Film, its another mis-question. Just as stated. its up to the photographer not the technology to decide which is best for a particular shoot. Much like 35mm did not replace 120 film format of which Medium film format did not replace Large Format. Its just that newer technology usually breed new media that suit even more people and in cases like 35mm, 1 hr. Lab, Color Film, Digital Camera, create and fulfill mass need better and thus are far more wide spread in use.
Ultimately Digital capturing might fulfill the need and the quality demanded for even the most strigent, but as of the near future, Film is here to stay, and likely so for a while. Different setup is catered for different people.
I remember way back the same kind of argument about Paperless Office when the Computer come of age, and the freedom to explore and shop when Internet Hype is high. So what do we have now ..... Make you reflect on that right !!!

傳統機，快狠準，聽聲已爽，手感佳(有dslr另計)
dc，隨便用隨便影，練習構圖取景記錄日常生活點滴，都係正。我諗dc只係取代了好多傻瓜機lor。
見過好多人去旅行淨用dc，番來張卡壞左，喊到無謂啦。菲林安全感都係大d。 |

有朋友去旅行, 去到邊沖晒到邊, 佢話有時貴成倍都值, 旅行不竟要洗錢,
菲林當地沖晒少一次X光, 又可以睇O下當地沖晒水準、用料(相簿、片套)及操作習慣.
上次上貴州都有試過係當地酒店沖SLIDE, YEN19咋, 仲沖得幾好, 順手試埋相機有冇壞.

"問題是DC甚麼時候會取代傳統SLR?”
DC = 135 P&S (in product nature)
135 P&S never replaced the SLR
ANS: DC will never replaced the SLR (the DSLR is another story)

番來張卡壞左，喊到無謂啦。~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
喱個籍口最基本,SLR.有人問睇相就話影正片.
得閒想睇正片就話沖壞,慳錢.又無減底影相興趣.兼吹水..... |

ccd技術而家仲未成熟
如果真係要玩數碼機
咁就最好買單鏡數碼機啦
可惜而家選擇太少同埋仲有好多缺點 |

點先叫成熟? 菲林技術成熟左未?
