如果只以晒4R or 5R size的相計

500百萬與700百萬有分別嗎?
（細緻度、解像度等......）


請高手們指點一下!

[老叟]

完全無分別!!

[Philippe]

4R只需要300百萬像素,再多都冇分別.

[dawnlai]

如果影的主體大小相同,做剪裁時,700萬會比500萬像素保留多一點細節。

[bolie]

我也想問...

610萬像,最大可以晒到多少size的相???

"完全無分別!! "

This is completely wrong, for the same image size, higher pixels reserves more details. I am not talking about developing 3R or 4R photos.

[tam_dominic]

" 晒4R or 5R size的相 " 只要 2 百萬像素 !

500百萬像素的相機 must be a large format digital camera ;^)

[man1492]

" 晒4R or 5R size的相 " 只要 2 百萬像素 !


I supposed the optimal size for 2M pixels picture is 3R.

"I am not talking about developing 3R or 4R photos"...........
但係.....man1492，人地係問緊晒3R or 4R photos喎...........
500百萬與700百萬晒3R or 4R photos係完全無分別........
老叟is completely correct........

可否詳細些少講解下你的意見呢?

我post問這個問題其實係因為去買相機，d sales成日話無分別
但有時睇d測試報告又話甚麼"800、700萬解像力強d"

To：All

不必計著我的問題
最緊要話我知像素與質素的關係

[yzcat]

For fixed dpi (dot-per-inch) printing, 7M gives 18% larger area than 5M.
This 18% gives you the flexibility to "剪裁" your photos and, at the same time, keeps your required resolution unchanged.

Do you do post-processing after taking photo? If not, forget it!

"但有時睇d測試報告又話甚麼"800、700萬解像力強d""

It is very simple, using MORE physical pixels (cells) to show the same thing.

你是指用printer print相嗎?

那麼到晒相鋪晒相又如何?

7mm....要清楚你個問題先可以準確咁答你架嘛...如果唔係..人地答既野根本唔係你想聽既野，晒你自己時間之餘亦晒其他答你既人既時間.......

講番先，如果你影完之後立即走去晒，咁500百萬與700百萬o係細緻度、解像度等方面都冇分別..........
但係500萬可以crop相既空間就細d........
晒4r只要300萬像，700萬像你可以crop走400萬像都唔會影響出既個質素，但係500像素而又要出黎既質素唔會受影響呢，就會只有200萬crop既空間喇........
咁明唔明白？

[ousi]

如果枝鏡唔正就唔同咁話.

e.g.
z750 vs w5 or even 5700/f717/a1

我就話5700同f717同a1都比架z750好好多la.

到時真係crop, z750可crop而仍保留okay resolution的空間其實也不多
