Conference Room Faces: Illuminating Faces for Video Conferencing

A video conference room with special attention to vertical illuminance. In addition to general desk lighting, above the wall facing the camera, there is a row of soft front lights directed towards the participants, illuminating the faces of those sitting at the table from the front. Skin tones are natural, eye sockets have no dark shadows, and expressions are clear. The background wall for the camera has uniform wall-washing light, with brightness slightly lower than the faces, preventing people from becoming silhouettes. Ceiling luminaires are not directly above people, avoiding bright tops of heads and dark faces. A corner of the image shows a comparison with an incorrect state: only ceiling downlights are used, resulting in dark shadows in the eye sockets and under the chins of people, making them look tired. Avoid: both states looking identical, the background being brighter than faces, installing downlights directly above people, using low color rendering index light sources.

一間視訊會議室,照明特別處理垂直照度。除了桌面的一般照明之外,面對攝影機的那一側牆面上方設有一排朝向與會者的柔和面光,把坐在桌邊的人的臉正面照亮,膚色自然、眼窩沒有黑影、表情清楚。攝影機的背景牆有均勻的洗牆光,亮度略低於人臉,不會讓人變成剪影。天花的燈具不直接在人的正上方,避免頭頂亮、臉部暗。畫面一角以錯誤狀態對照:只有天花下照燈,人臉的眼窩與下巴出現黑影,看起來疲憊。避免:兩種狀態看起來相同、讓背景比人臉亮、在人的正上方裝下照燈、使用低演色性的光源。
