I was able to capture this macro photo of my eye by using the Smart Remote Control app which allows me to check the focus on a smartphone while facing the camera. I set the lens to its minimum focusing distance and to manual focus, I then moved my head back and forth until the eye was in focus and took the shot. I had to place a strong diffused light source close to my eye to bring out the details in the iris.

我透過了Sony的Smart Remote Control app來拍攝這張自拍微距，它讓我可以透過手機來控制相機還有確認焦是否有對到。對焦有點困難：將鏡頭設為手動對焦並且轉到最近對焦距離，然後稍微在鏡頭前移動我頭的位置直到手機上看起來是準焦。拍攝中才發現需要足夠的光才能將眼裡的細節顯示出來，因此我用了一盞強燈配上柔光罩，距離貼近眼睛的位置打光。
