用法說明
How is "Aperture" different from similar structures?What usage mistakes are common with "Aperture"?
aperture 與 f-stop
- aperture 是一個物理孔徑，指相機鏡頭中讓光線通過的開口。它是一個具體的、可測量的結構。
- f-stop（或 f-number）是一個數值，表示鏡頭焦距與光圈孔徑直徑的比率（例如 f/2.8, f/8）。它是一個用於量化光圈大小的相對值。
- 簡單來說：aperture 是那個「洞」，而 f-stop 是描述那個「洞有多大」的數字。
- 在攝影中，人們常說「開大光圈」或「縮小光圈」，但實際調整相機設定時，改變的是 f-stop 的數值。
對比範例： EN: A lens with a wide aperture lets in more light. 翻譯: 擁有大光圈的鏡頭能讓更多光線進入。
EN:To achieve a shallow depth of field, set your camera to a low f-stop like f/1.8.
翻譯:要獲得淺景深，請將相機設定為較低的 f 值，例如 f/1.8。
總結建議
在技術討論中，使用 aperture 指光圈的物理概念，而使用 f-stop 或 f-number 來指具體的設定數值。
易混淆對比
What is the difference between "Aperture" and similar words?How to choose "Aperture" vs alternatives?
aperture vs opening
「aperture」通常指一個有控制、有特定功能的開口，如相機光圈或儀器的孔徑；而「opening」則泛指任何類型的開口、洞或開始。
aperture vs hole
「aperture」通常指設計上或功能上精確的開口；「hole」則常指意外產生、破損或單純的洞，可能不具特定功能。
aperture vs gap
「aperture」指一個允許光線或物質通過的「開口」；「gap」則強調兩個物體或部分之間的「間隙」或「空缺」。

引述
當重複或引述他人關於攝影、光學或比喻性「開口」的說法時使用。 EN: He kept going on about "finding the perfect aperture" for the shot. 翻譯: 他一直在說要為這張照片「找到完美的光圈」。
EN:My teacher always says, "Your mind's aperture must be open to new ideas."

EN:The contract has a very narrow aperture for making changes after signing.
翻譯:這份合約在簽署後，允許修改的空間非常狹窄。
停頓填充
在思考如何精確描述一個開口、限制或攝影設定時，作為短暫的停頓用詞。 EN: The light comes through... the aperture... in the ceiling. 翻譯: 光線從...天花板上的...孔洞照進來。
EN:You need to adjust the... uh... aperture to get more light in.
翻譯:你需要調整...呃...光圈來讓更多光線進入。
正式寫作注意：在正式或學術寫作中（如科學論文、技術報告），應避免將 "aperture" 用於上述口語的停頓或隨意引述情境。應直接、精確地定義或使用該術語，例如直接說明「光圈值設定為 f/2.8」或「孔徑直徑為 5 毫米」，以保持專業與清晰度。

常見錯誤
What are common mistakes with "Aperture"?Which "Aperture" sentences look correct but are wrong?
×The aperture of the camera is too dark.
✓The aperture setting is too small, making the image dark.
Aperture itself is not dark or bright; it's the size of the opening. Use 'small/large aperture' or 'aperture setting' to describe its effect on exposure.
×Open the aperture more to get a wider depth of field.
✓Open the aperture more (use a larger f-number) to get a shallower depth of field.
A larger aperture (smaller f-number) actually creates a shallower depth of field (more blurry background), not a wider one. 'Wider depth of field' comes from a smaller aperture (larger f-number).
×I adjusted the aperture to make the photo sharper.
✓I adjusted the aperture to control the exposure/depth of field.
While aperture affects sharpness indirectly (via diffraction at very small apertures), its primary purposes are controlling light intake (exposure) and depth of field. 'Sharper' is usually a result of lens quality, focus, and shutter speed.
×The lens has a good aperture.
✓The lens has a wide maximum aperture (e.g., f/1.4).
Aperture is a variable setting, not a fixed quality. What is often praised is a 'wide' or 'fast' maximum aperture, which allows more light in and enables shooting in low light.
×Please check the aperture in the camera screen.
✓Please check the aperture setting/value on the camera screen.
You cannot see the physical aperture hole on the screen; you see the numerical setting (f-stop). It's more accurate to refer to the 'aperture value' or 'aperture setting' displayed.
