Nerd Mode Activated 宅男的攝影模式

##### I've always wanted to do water droplet photography after seeing the cool images online taken by others. Today I would like to share with you my first serious attempt at water droplet photography! ##### 自從在網路上看到許多水滴攝影的作品之後，自己也一直想來試試看。今天我就來分享我第一次認真拍水滴的一些作品及過程吧！ # ![_MG_8380.jpg](https://steemitimages.com/DQmU3nnFYkqmoChL4CLtZyBUvyoMgHsPg4qxRLJ7RymfmNT/_MG_8380.jpg) ^{1 s | f/11 | ISO 400} ##### To control the water drops, I used an Arduino hooked up to a simple circuit that opens and closes a solenoid valve automatically at regular intervals. ##### 我用了一塊Arduino配上簡單的電路去控制一顆電磁閥開關，達成自動滴水裝置。 # *** ## The Code 程式 #

##### The code is very simple: set pin 13 to output mode, then toggle it on for 250 ms, then off for 1500 ms, and repeat. ##### 程式非常簡單：設定pin 13為輸出，然後開250 ms，接著關1500 ms，重複開關。 *** ![_MG_8376.jpg](https://steemitimages.com/DQme6H3vvWC15cnZY2Fg6iD1qTgmc1NcKQaazxRsahJc8YL/_MG_8376.jpg) ^{1 s | f/11 | ISO 400} *** ## The Circuit 電路 #

##### The circuit consists of an Arduino connected to a TLP250 optocoupler which is used to drive a 24-volt solenoid valve. ##### 電路基本上是一塊Arduino連接到一顆TLP250光偶合IC來驅動一個24伏特的電磁閥。 *** ![_MG_8399.jpg](https://steemitimages.com/DQmTaryL5zq8GhWXm8ia5oxP94Z3QGwdd7oGrhV4JHbh4WJ/_MG_8399.jpg) ^{2 s | f/11 | ISO 400} *** ## The Setup 架設方式 ##### With the electronics ready, the rest is just setting up the valve with a reservoir raised above a pan full of water used to catch the drops. A flash and reflector is placed at the pan to light the image. ##### 電子的部分搞定後，剩下的就是把電磁閥及水槽放置在一個接水盤的上方，讓後在接水盤旁邊架設閃光燈及反光板。 # ![setup1.jpg](https://steemitimages.com/DQmXMAHNC6PzQnx73LdS788tikGWoy4dKfmNJZ4yDgist5j/setup1.jpg) ![setup2.jpg](https://steemitimages.com/DQme8NpwyBjUjFXVfhZ43NdXYQNUJjiHD6q2ptvjyv7iUTR/setup2.jpg) *** ![_MG_8402.jpg](https://steemitimages.com/DQmcmGqcq8KxXPUJZttKYE5LGAmF78PGdWmqvxKzwziWRyv/_MG_8402.jpg) ^{2 s | f/11 | ISO 400} *** ## Taking The Photo 拍照方法 ##### I set the camera to 1~2 seconds exposure, f/11 at ISO 400. The flash is set to 1/8 power. With the lights turned on and the water dripping into the pan, I pre-focused the camera at the location of the water drop. Then I turned off the lights in the room except for a dim lamp. For each shot, I start the exposure, then I fire the flash manually when I see the water droplet hit the surface of the water in the pan. The short flash duration is what captures the images. ##### 我將設定調成1~2秒曝光時間、f/11、ISO 400、閃光輸出1/8，厨房燈開著時把對焦設在水滴打到接水盤的位置。拍攝前先把燈關掉，留下一盞小夜燈開著。拍攝每一張照片是先按快門，然後看著接水盤，當水滴掉落時手動觸發閃光燈。照片其實是透過閃光燈短暫的一閃來捕捉一瞬間的影像。 *** ![_MG_8416.jpg](https://steemitimages.com/DQmVJ677WaEgBrhUiievXAf7W5QZh91hcwUUKv55np6UfEL/_MG_8416.jpg) ^{2 s | f/11 | ISO 400} ![_MG_8427.jpg](https://steemitimages.com/DQmUJBmdbpuMtvSpev2xTSnxGFECi3mpfmnbRh61QckJqtH/_MG_8427.jpg) ^{2 s | f/11 | ISO 400} *** ## Equipment Used / 使用攝影器材 - Camera: Canon EOS M - Lens: Canon EF 100mm f/2.8 - Flash: Canon Speedlite 430EX II - Software: Adobe Lightroom
