請問200萬像素晒4R有無問題?

[chanchan316]

理論上應該冇問題

[Canon Man]

in 90% of cases, no problem. also depends on the compression amount. if your 2MP image is about 1MP or bigger, u can get film quality print already.

4R 4"x6" 要最少 900 x 600 成像 = 一百五萬像

Many cheap 2M DC do not have a good lens. The photo colour and sharpness are not good.

If use a 4M DC and store the photo as a 2M photo. OK.

200萬像素晒4R夠哂，放心。

但好似出面晒相都係300dpi.200萬好似都唔係好夠.如果以200dpi去晒.就夠.但我都想問下.300dpi同埋200dpi相差幾多呢.
或者用"極佳"."佳"去影相.晒出黎4r會相差大唔大呀.睇落會唔會差好多呀

[oldcrazy]

如果照用300dpi去除，200百萬像可以晒4"x5.33"，佢唔會問你用幾多dpi去晒的，300dpi只係一個參考數，我覺得最好搵ｄ相去晒o下，你覺得ok就得啦，而家晒相咁平。

我之前用a40晒4R相，絕對無問題，我仲覺得好好tim。我覺得好多人話200萬像的相機晒4R相有問題是因為很多200萬像素的相機都屬低檔相機，無論鏡頭及其他地方都不太好，所以形成200萬像的相機晒4r相唔好的錯覺。

如果你仲想玩埋DV的話可以考慮買CANON部MVX10i有220萬像素一機兩用不過要成$9000左右

唔係咁計既..

200萬像,當係1600x1200啦, 其實幾大同print quality 無真接關係,因為DC係optimized for screen viewing, 而windows 係96ppi (pixel per inch, Mac機係72ppi, 呢個一向係industrial standard) 1600/1200除 72, 大約得出最佳screen size 係22.2寸x16.7寸既mon.

轉做dpi (dots per inch)又係另一回事, 如果用300dpi 黎print, 咁300/72大約係4, 即係用4x4=16個dot去print一個pixel, 考慮到printer既色比screen少,好多時要用幾個甚至十幾個色點去表現一個色,16dot per pixel就唔夠啦. 解決方法係將圖像compress 4倍, 即係print 出黎係5.5寸x4.175寸, 4R係6x4,200萬像夠啦

講錯既話,請高手指正

補充,影既時候用fine/normal 等,係mon睇係無分乜別的
但係print出黎就當然係fine好啦
