因為我的中文寫作技巧是有限公司, 讓我從互聯網上引用一非常簡單的文章，以解釋倫勃朗照明人像攝影用光.

倫勃朗是世界著名的荷蘭畫家。倫勃朗式用光是一種專門用於拍攝人像的特殊用光技術。拍摄时，被摄者脸部阴影一侧对着相机，灯光照亮脸部的四分之三。拍攝時，被攝者臉部陰影一側對著相機，燈光照亮臉部的四分之三。以这种用光方法拍摄的人像酷似伦勃朗的人物肖像绘画，因而得名。以這種用光方法拍攝的人像酷似倫勃朗的人物肖像繪畫，因而得名。

倫勃朗式用光技術是依靠強烈的側光照明使被攝者臉部的任意一側呈現出三角形的陰影。它可以把被攝者的臉部一分為二，而又使臉部的兩側看上去各不相同。如果用均勻的整體照明，就會使被攝者的臉部兩側顯得一樣了。

這種用光技術相當有效，因為它突出了每副面孔上的微妙之處，即臉部的兩側是各不相同的。其用光效果還可根據攝影者的意願用輔助光任意調節：雖然倫勃朗式用光的高反差形式令人感興趣，但適當運用反光板和輔助光，盡量減少反差，能取得加強整個肖像的效果，從而拍出不同凡響的作品。一般採用倫勃朗式用光需要兩盞燈照明，經過改進後再加用第三盞燈用以調節反差。

·攝影入門須知倫勃朗式人像攝影用光兩盞照明燈中，一盞650瓦的石英主燈(A)置於攝影師左上方，直接照在被攝者臉部的右邊，就像他正面的一盞柔光輔助燈(B)一樣。它能把一些光線反射到臉部沒有照明的一例。而頭髮燈(C)能通過反光板把光射到被攝者的臉上，削弱了明顯的倫勃朗三角，並加亮了肖像的總體色調。而背景燈（D）則是起到打亮背景的作用。

具體拍攝時，先打開650瓦的石英主燈(A)，並調節其角度，使倫勃朗三角光投在被攝者臉部的暗側。然后打开正面主要的柔光灯(B)，直接对着被摄者脸部的亮侧。它能照亮被摄者的脸部并增加深度，但此时三角状的亮光区域仍很明显。设法使被摄者转动头部，直到伦勃朗三角光能恰到好处地照在他的面颊上为止。設法使被攝者轉動頭部，直到倫勃朗三角光能恰到好處地照在他的面頰上為止。并要被摄者的下巴下倾。並要被攝者的下巴下傾。接下来就是测光及选择相机的光圈与快门组合。接下來就是測光及選擇相機的光圈與快門組合。最後再檢查一下背景，看一下頭髮燈是否會在背景上留下亮點及在相機鏡頭中引起暈光。

開始拍攝時可同被攝者輕鬆地交談，以使他放鬆並面帶笑容，這一步也是很關鍵的。須記住，在人像攝影中重要的是不要讓一種技巧的作用超過了被攝者臉部的表現力。

Hoping this will be of some help...!!

Well, depends on which model la. even with the most experience model, it is always very important ...

多謝芬龍兄教。
我看相時問自己，點解影正面都冇"大面砵"呢?
初時以為系化妝，跟住再睇光暗位置，唔似化妝做成，
所以有此一問。

setting up Rembrandt lighting for Ladies with high ( strong is a better word) Cheekbones are a little tricky and involves some trial and error to get it right.

The preferred set up would be call Paramont or Butterfly Lighting. The term, "Butterfly Lighting," comes from a characteristic butterfly shaped shadow beneath the subject's nose.
If you want to use butterfly lighting you should line your Main Light up along your subject's nose axis and then raise the light until you see the characteristic shadow. This style of lighting is also known as glamour lighting because it was used extensively by the great Hollywood portrait photographers of the '20s, '30s and '40s. Although light placement is identical for butterfly and glamour lighting, photographers such as George Hurrell gave it a special look by using a spotlight as the Main Light rather than a softer light source. If you move your Main Light a little to the left or right, you will change your lighting style into a modified butterfly pattern.
Paramount Lighting, sometimes called Butterfly Lighting for the shape of the shadow it forms under the nose, is a female glamour lighting style. It works best for women with strong cheek bones and good skin. This lighting is not typically used with male subjects.

The key light is placed high with the fill light directly under it. Keeping the light close to the subject, watch for the butterfly shaped shadow to form under the nose. Be careful not to place their eyes in shadow.
The fill light is placed at roughly head height and can be accompanied or replaced by a reflector under the face to lighten the shadows under the chin and lower cheek.
