攝影｜閃燈的功能
前幾天在拍攝活動的時候，有好友詢問我在這樣的場地燈光下，為什麼還要再放置閃光燈在舞台兩旁？
A few days ago during the event shoot, a friend asked me why we still needed to place flashlights on both sides of the stage under this kind of lighting environment.
拍攝的方式有很多種，每個人拍攝風格和方式都不同，我在這場活動這樣做的原因是我想要讓我想要拍攝的主體還有背景能達到我想要的亮度，兩者的亮度也不要相差太多。另一個原因就是我想要矯正室內LED燈光發出的綠色。
There are many ways to capture a photo, and each person has their own style and approach. The reason I did it this way during this event is because I wanted to achieve the desired brightness for both the subject I wanted to capture and the background, without a significant difference in brightness between them. Another reason is that I wanted to correct the green color emitted by the indoor LED lights.
通常我們在對比攝影師用閃燈的同時，是用自己眼睛看到的亮度來做對比標準，這其實會有很大的誤差和誤會。人體的眼睛能看到的光線和和明亮對比，相較於現在大眾手上的相機來說，太過於強大或者說現在的相機還有很長的一條路要走，還有很多的技術要克服。一般人不常操作相機當然也不能理解相機能做到什麼程度的拍攝，這時候攝影師聽到這類言論其實都蠻苦惱的。苦惱的點在於要怎麼描述才能讓站在面前的人理解到眼睛和相機的差距。
你說：直接拿相機拍到的畫面給他看就好。可是在拍攝的時候，我已經把畫面控制到我覺得跟眼睛看到的畫面差不多。我的意思就是只是看相機內的畫面其實不太準，相機有些還內建濾鏡，比較好的做法是把拍攝好的原始檔案放到電腦上展示，在所有參數都沒有調整的情形下，比較容易看出差異感。
In general, when comparing photographers using flash, we often rely on the brightness seen with our own eyes as a reference, which can lead to significant errors and misunderstandings.
The human eye’s ability to see light and contrast is much more powerful compared to the cameras available to the general public today. Cameras still have a long way to go and many technical challenges to overcome.
Ordinary people who don’t often use cameras naturally can’t understand the extent of what a camera can achieve. This is where photographers feel quite troubled when hearing such opinions. The trouble lies in how to describe in order to make the person in front of them understand the difference between the eyes and a camera.
You say: Just show him the footage captured by the camera. However, during the shooting, I have already adjusted the visuals to be similar to what I see with my eyes.
What I mean is that simply looking at the camera’s screen isn’t very accurate. Some cameras have built-in filters. The best approach is to transfer the captured raw files to a computer for viewing. In a situation where no parameters have been adjusted, it is easier to perceive the differences.
所以，通常聽到這樣的言論，我只能再補充說明第二點，我想要矯正室內燈光的顏色。
So, typically when I hear such comments, I can only add that I want to correct the color of indoor lighting.
顏色是我認為影響比較大的一點，當然這也是我自己拍攝的風格跟方式的關係。我會希望整體顏色都要盡可能接近眼睛看到的顏色，甚至是印象中正常的顏色。最明顯的地方就是人的皮膚顏色。畢竟，人像整體佔最大畫面就是皮膚，所以只要畫面裡皮膚顏色不太符合我自己要求的話，我就會感到不太舒服。
Color is a significant factor that I believe has a big influence, as it is also related to my personal shooting style and approach. I would prefer the overall colors to be as close as possible to what the eyes see, or even the normal impression of colors.
The most obvious aspect is the person’s skin color. After all, the skin occupies the largest portion of the frame, so if the skin color in the image doesn’t meet my own expectations, I feel uncomfortable.
這次活動在室內使用的燈光是LED燈管，由於在當天之前有施工更換過，所以，我自己是覺得對比以前同樣場地下顏色跟亮度有更好的轉變，但是顏色還是會偏向綠色。有時候，閃燈沒有照射到的那一瞬間畫面，我還是可以進修圖軟體處理到顏色不會偏色太誇張，不過，我的想法是：如果能在按下快門前就可以避免問題的產生，對我之後處理照片是更方便也會更快速。
而想法就會產生行動，我的作法就是在不干擾活動、人群走動的前提下，把我所有閃燈燈光範圍覆蓋全場或者重點範圍。
The lights used for this event indoors were LED light tubes. Since they had been replaced before the event, I personally felt that there was a better transition in terms of color and brightness compared to before. However, the color still tended to be green.
Sometimes, if the flash doesn’t capture the moment, I can still use photo editing software to adjust the colors and ensure they don’t look too exaggerated. However, my idea is that if I can avoid the problem before pressing the shutter, it would be even more convenient and faster for me to process the photos later.
And ideas will generate actions. My approach is to cover the entire venue or key areas with my flashlight, without disturbing activities or the movement of people.
以上就是我認為要使用閃光燈的原因。
Above is my belief in the reasons for using a flash.
題外話：跟好友的聊天過程，另一位好友其實也幫腔替我說道：攝影師總是有他自己的堅持。這是一句我覺得很棒的恭維，不只是替攝影師說話，也讓攝影師感到暖心。有第三人幫忙附和的時候，也同時在為攝影師的言論做一個贊同，也讓攝影師的話更有公信力。
這一點只要是人跟人之間的相處都可以用得上。
Sidebar: During a conversation with a friend, another friend chimed in and said, Photographers always have their own beliefs.
This is a compliment that I think is great. It not only speaks for the photographer but also warms their heart. When there is a third person helping to agree, it simultaneously adds credibility to the photographer’s words.
This is applicable in any human interaction.
