Photos of Coral Beach

I went out to Coral Beach near Carraroe yesterday, and while I was out there I snapped some photos. That isn’t sand you’re looking at, it’s pieces of coral! Or more correctly, coralline algae. But still, it’s beautiful even on a rain day…

How far would you go to get a good photo?

Would you think of taking them from a slightly differnt angle? Would you think of leaning over a cliff? Or would you spend however many millions to put a 15 tonne telescope in the back of a 747?

This one works in the infra-red, which is a problem for ground-based telescopes because water vapour absorbs some of it – and it’s already found something nobody else has spotted. From the article above:

thanks to the vision of Sofia’s Forcast instrument, it has become clear that something else is shining bright in the region, deep in the infrared

They also snapped some photos of the Orion Nebula, and found an molecule made of just one atom each of hydrogen and sulphur – apparently, this doesn’t happen on Earth. Either way, try carrying that telescope around!

Raindrops in the lab

My next experiment for the next three weeks is to examine how water droplets interact when they hit a surface of water. The idea here is that a beaker of water acts as a droplet of infinite radius, and if the smaller droplets hit the surface of the water at a critical angle, they will not bounce off the surface, but will merge with it (aka coalescence).

The apparatus I have is a canister of compressed air, connected to a jar of water which in turn is connected to a pump. The pump’s wired up to a frequency generator that allows the droplets through at an adjustable frequency. I have a strobe light fixed on the beaker of water (not a good idea if somebody has epilepsy, which I fortunately don’t), and if I correctly adjust the frequency and the height of the beaker above the table, it looks as though the droplets are standing still in mid-air, or even travelling backwards! How cool is that?

The really cool part, from my point of view, is that I have to take photos of this happening! A camera is provided, but I’ll probably bring my own in anyway to try and snap some videos of the droplets moving “in reverse”. If I can, I’ll upload them here. Watch this space!

New Camera!

Myself and my Dad went into our local MediaWorld and bought a new camera. It’s a FujiFilm S3200, with a 24x optical zoom and 14 megapixels – the zoom being the priority. We also got a case and an 8GB memory card, which should come in handy for snapping photos around Galway!

Can you break the “Rule of Thirds”?

In photography, the Rule of Thirds is a rule of thumb for composition which states that an image should be divided into nine equal parts to maintain interest and/or tension. That said, it’s just a rule of thumb.Here is a post I found on when and how to bend or even break it.
