Underwater full HD video-graphy inside my home Aquarium using my Sony Xperia Z. If you guyz also want to try underwater video-graphy with Xperia Z, follow these steps:
a) Put your Camera mode to Video. Set HDR as the scene mode (optional).
b) Click on Video recording.
c) Take the camera down inside water. ( Please note: You cannot turn on the touch switches inside water).
d) Take as much video as you want ( till 25 mins - though the official guidelines tell 30 mins)
e) Bring the Camera out.
f) Dry it with plain cloth. Do not jerk the phone inside water or outside it.
g) Remember not to hold the camera over the MIC or you will lose all audio.
In case you are facing any difficulty shooting underwater, write to me @ tridib.ghosh[at]gmail.com.
