相機CMOS感應器清潔(The Camera Sensor cleaning)

 

本篇介紹有關簡單的相機CMOS感應器清潔方法,很多攝影人一直以來都很困擾的問題就是如何清潔相機的CMOS感應器而不會損壞感應器,尤其在戶外頻繁更換鏡頭後經常在CMOS感應器上附著許多的髒污顆粒,一些較大肉眼可見的顆粒可用橡膠噴嘴將其噴除,但一些肉眼無法發現的微小顆粒即無法去除,因此後製時,在有淺色天空的影像上會有明顯的黑點,增加後製工作的困難及時間,一般人此時都會將相機送去代理商代為清潔,但如果只是要清除一些看不見的微小顆粒,其實只要有適當的工具可以在家輕鬆的DIY將之清除。

Today I like to talk about the simple and not complicated way of cleaning of the camera sensor, to clean the sensor by yourself is always a kind of headache to many photographers, one of the most is afraid of damaging the sensor, when you change frequently the lens on location, there are always some tiny dirt on the sensor, normally we can remove the dirt which can be seen, but not those can’t be examine by the eyes, on the post-processing you will see the spot dirt on the image with light sky on the pc, which will be more troublesome and time consuming, then many people will send the camera to the shop for cleaning, but for just those tiny dirt you are able to do the DIY cleaning with suitable tools.

以下是個人DIY清除CMOS感應器的一些經驗分享,主要資訊是來自紐約知名攝影師Neil Van Niekerk的啟發:

I will share my experience the following about how to do the DIY of cleaning the sensor, and it is inspired by the noted NY photographer Neil Van Niekerk:

器材(Gears):可自Amazon或B&H採購(Can be found on Amazon and B&H)

  1. 凝膠棒(Sensor Gel Stick)
  2. 相機感應器放大鏡(Camera Sensor Magnifier)

相機設定(setting)應先檢查相機有足夠的電力以防工作中反光鏡因電力不足而覆蓋。

Before the cleaning steps, you have to check the camera power is full to support your cleaning job against the fall off of the reflecting mirror.

在清潔前找一白色背景,以相機拍攝一張影像輸入電腦後放大檢視污點的狀況,清潔前應先了解有關相機”手動清潔感應器”的說明,在選項中選擇”手動清潔”,當反光鏡揚啟後即可進行工作,先用橡膠噴嘴將相機開口內的可見髒污噴除,再將感應器放大鏡置入相機的開口,轉動放大鏡鏡頭直到能看到清楚的感應器表面,此時將放大鏡頭移到一邊,用凝膠棒輕輕的接觸感應器表面將微細的顆粒粘除,要清除附著在凝膠棒上的髒污顆粒,可利用廠商隨器材附上的特殊粘紙來清潔,將清潔後的感應器再拍一張白色背景圖像輸入電腦放大檢查,反復此項工作直到完全清潔為止。

Firstly, take a photo of the white wall or paper and check it on the pc to see the situation of the spot dirt on it, find out the manual of the camera on “manual cleaning sensor” instruction, starting the DIY cleaning when the reflecting mirror is up, first clean the sensor chamber by rubber blower, then fitting the “Camera Sensor Magnifier” into the chamber, turn the magnifying lens until you can see clearly the sensor surface, move the  magnifying lens to the side and use the “Sensor Gel Stick” gently touching the surface of the sensor to stick the dirt away, to clean the head of the “Sensor Gel Stick” by using the sticking paper equipped, to repeat the steps above until you can’t see the spot dirt.

注意事項

  1. 以上的說明只限於輕微的感應器污點,如是嚴重的污染情形還是建議送去代理商處理。
  2. 以凝膠棒沾粘感應器表面時應控制力道以免損壞感應器表面,器材廠商將不負過度用力或其他不正確使用而造成損壞的責任。

Be noticed:

  1. The explanation above on the DIY cleaning of the camera sensor is belong to the easy cleaning situation, but not suitable to the serious dirty sensor, it is then recommended to send to the concerning shop for the professional care.
  2. It should be very gently when using “Sensor Gel Stick” to touch the sensor surface, the manufacturer will not be responsible for any damage caused by impropriate operating which not following the manual stated.
