i am a newbie, i have read the "人像焦距應用（上集）" provided here, the words "透視感" is too abstract [抽象] for me, does anyone help to explain or give some examples? thank you very much and sorry that i dont know input chinese.

要知到一張相其實係一張紙，一張紙何來透視感或立體感？就要作者運用攝影技巧去表達。

簡單的透視感例如影一條火車路，在畫面中間一直向前去到無限遠，作用把觀賞者的視線由面前帶到無限遠。

Yes, 透視感 is too abstract because the word "感"

透視(perspective) is not abstract at all.

It is very easy to understand, just find basic books of
素描 and flipp a few pages.

Happy shooting !

簡單點說，在平面(相紙、畫紙或畫布)上展示物件(一件或多件)由近至遠的感覺，如近端大及遠端小。又或以陰影顯示物件的立體形狀。

有錯請指正。

understood, thank you all !!!

==> We take photos thru the lens of a camera.
Each lens is built on a fixed (eg. 28mm) or variable focal length (eg 70-300mm zoom)

The focal length decide the perspective in the photo.
eg. 28mm lens has a closer vanishing point
300mm lens has a farther vanishing point.

影響透視感o既唔係焦距﹐係攝距。
名位置唔同焦距得出o既透視感係一樣o既。

micro 兄,

"同位置唔同焦距得出o既透視感係一樣o既。"

閣下的看法在攝影圈很流行
但與我念 立體設計中的 透視 不同.

可否介紹些 出版了 的典籍
給小人研習嗎 ?

謝謝 .....

[tam_dominic]

micro 兄,

你是對的.
透視與焦距無關, 與攝距有關.

剛才小人說錯了, 請各大人見諒.

Happy shooting !

我無正式讀設計 ...... 立體設計中o既透視又係點o既呢﹖
我o既理解係於 2D 上表達 3D﹐即係前後距離o既關係。
