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！

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。

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。

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。

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。
