想同大家分享一下個主題, 更加想話比大家知, 其實 Nikon.com 上面有很多資源. 有時自己肯花時間睇下 manual, 在 internet search 下, 買機時又有 lesson, 會學得仲多.

=================================
很多人認為數碼相機的像素愈高，影像質素便愈好，因此他們在選購買數碼相機時都首要考慮高像素型號。但像素是甚麼？為何這樣重要？簡單來說現在的數碼影像均由很多顏色點所組成，而像素正是該些顏色點，例如一千萬像素就意味著該張影像檔案是由一千萬個顏色點所組成。而當像素愈大，可輸出的影像面積也可較大，因此職業攝影師都會追求較大像素的數碼相機以便製作較大型的廣告宣傳品。雖然像素對於輸出較大面積相片有正面的幫助，但高像素並不代表擁有高質素的影像。除了像素外，鏡頭的銳利度、感光元件面積、以致影像處理器輸出的位元數都直接影響著影像的質素，因此我們不能夠單看像素而片面地定奪哪一部相機擁有較高質素。對於普羅用家而言，並無追求高像素的必要，皆因「一闊三大」，高像素便需要較大容量的記憶卡及硬碟以儲存足夠數量的影像。其實大家只要依據自己慣常輸出相片的面積，便可選擇合適自己的數碼相機，以下便列出像素與輸出比率圖表供大家參考。

像素
可輸出最大面積

　一百萬像素
　2R相片
　二百萬像素 　4R相片/A6面積
　三百萬像素 　5R相片/A5面積
　六百萬像素 　8R相片/A4面積
　八百萬像素 　12R相片
　一千二萬像素 　A3面積

明白自已要什麼的人又有幾多人
最重要是要　”威”要　”貴　”要　”型”．

其實一直都覺得家用既話8佰到一千萬左右已經差唔多,講真有幾何會晒12R丫?!
不過高像素嚮裁相既時候真係有須要, 如果得2佰萬既裁得兩裁到時連2R都晒唔出.
所以千二到千伍萬左右家用真係好夠.
不過, 鐘意聞相同聞MON人仕除外~~~

高像素0係 crop 方面着數好多

[snoopybee]

同意 crop 相係方便左. 我會從第二個角度睇, 如果我按個快門前已經做好 "功課", 根本就沒有需要去 crop 相.

我都有時會 crop 相, 但係唔會 "因為我要 crop 相", 而去用 high res.

Just my 2c

[hkraymondccm]

snoopybee 師兄，其實我好同意你提出0既觀點，不過舉個例，好似打飛緊既雀，邊有得話構圖，咪只有用 crop ，我相信有好多打雀0既靚相都係 crop 。
反正有多就點都好過想要個陣發覺唔夠，好似 $$$ 咁......^_^ !!!

This is interesting.

IMHO, it is because some cameras have already provided 20M+ resolution. Being the consumers, they want to spend their money to get all the latest functions / features.

I can't speak for the others but myself only. For me, I don't know why DSLR needed to provide video recording?

For example the body is 7xx g + the lens with large aperture 6xx g. It is over 1kg. How long you can hold the camera to taking the video?

Back to the question, how many ppl will upload the file size > 20M+ into the online album? Assuming you got the plenty of space in your online album, the upload speed is still slow when comparing with the download speed.

My 2 cents..

I have a a4 size photo printed from 3 mp image years ago still look great.

See the canon advertisements why camera need to build-in video capture function。I think the general camera technology almost reach the limit. Do not have any practical, useful, powerful stuff can be improve. That’s why need to find someway to earn money.

Gimmick, promotion, give you try the capture video fun, then you will buy the Video Cam. I’m worry too many rubbish will appear at our world. Electronics Products, once outdate… meaning less worthless at all.


Megapixal... hahaha many people just happy to read the SPEC only. But donot spend more time to watch the result & truths.

[snoopybee]

Ramond bro, agree with you that under certain situations, it is impossible to frame the picture good enough. That's why I would also crop pics occasssionally.

Another point raising this post is to introduce Nikon's website and to make good use of the internet, rather than just posting many basic questions and expecting others to reply (aka shortcut).

還要計算COMS OR CCD有幾大. 好像Canon 30D磈COMS 己經大過40D 同50D.

[fathoz]

就算真係專業做商業野既攝影師, 都未必用得曬個千九幾萬像素啦......d file size 大到嘔, 買卡都買窮你.......

不過最緊要"靚 正 型 勁 貴", 始終有人去買......

[tkoalbert]

很多人在社會生活上得不到滿足,沒有認同.就會由其他途徑尋求滿足感.比如有些人會大吃大渴,不停買東西,高買尋找刺激..
攝影人最容易找到不同滿足感
影相靚有人認同,影相不靚買貴器材不會用也好看,影相不靚又無錢還可以吹水.....真是什麼人都有..
snoopybee兄
會去影相的人5百萬像素已經很好用,一班人出來影相,想信只有5%是認認真真.最近去社區中心教了幾堂,真是使人失望.年青人多是用來溝女.一定要型,要威,要貴啦

[mclarenkuen]

哈哈~變曬做器材"勞"
最緊要拎部機出黎要型比人睇(夠貴,夠型,夠新)
