遮光罩有甚麼用處?
在黃燈下用閃光燈會令到相片變白色, 沒有現場感, 用遮光罩可以改善嗎?

遮光罩係用來放止如側射的太陽光進入快門影響相片.
黃燈下想保持現場氣氛最好關閉閃光燈用長快門,不過記得要用腳架或用其他方法固定相機.此方法另一好處是背景會很清楚,不會像用閃光燈般只影到人.

1) To shield the glasses from unwanted light in order to cut down flare.
2) For protection.

No, it has nothing to do with lens hood.

1) If you DC has night mode, you can use night mode with flash when doing indoor or night photography with people as subjects. However, the shutter speed could be very slow and you might need a tripod.

2) If not, you can try ISO400, f2.8, 1/30-60s with auto flash. This might or might not work depends on your DC.

閃燈加顏色膠紙得唔得？

Thanks, 但我其實是想問在外置閃燈上那一個白色的磨沙膠蓋有甚麼用? (我以為它叫遮光罩ar)

To soften the flash light

如果室內光源夠的話,特別在燈泡光源下,強烈建議不要用閃光燈.相機內置的閃光燈加長快門模式雖然可以乜都影晒,但會面對前後色溫不一致的問題而引致人物是閃光燈的泠色調而背景嚴重偏黃.
