The Platypod is a mini holder for the camera that allows you to get these low angles. If nothing else that provides a different perspective.
The crew of our ship would wash the decks with hoses each morning. Because I have a habit of waking up before dawn, I’d see them and then use the Platypod to take photos like this. I guess we can call these types of shots low angle studies.
There are a lot of things to take pictures of on a ship, but after a while, I was wracking my brain for something new. Once I discovered this little trick, I made a ton of these studies. Eventually, it got old, and so the next time I go on a cruise, I’ll be looking for something else to keep me interested.
