According to the article:

The image was captured by Martin Gray at Gyran on Tuesday morning, who described the sight as "amazing".

He said: "I'm used to seeing double rainbows, but this was a really weird-looking thing."

[...]

"I quickly snapped a few photos. It was extremely bright, and odd looking - all odd angles. "But I didn't even notice the faint fourth arc until I carefully looked at my photographs."

BBC weatherman Simon King said it was an "impressive" photograph. "It's a really impressive double reflected rainbow," he said. He said the photographer had a loch behind him at the time.

As a result, sunlight had bounced off the loch before reaching the water droplets from a rain shower in front of him. The sunlight was then bent and reflected inside the droplet back to the photographer.

Question: I've annotated the image and numbered each of the arcs. Is it possible to sort out what's going on and which phenomenon are responsible for each of them?

The lighting outside the secondary is the natural lighting level.

One way of looking at rainbows is that they transfer some of the light that would normally fall between the primary and secondary to inside the primary, and that this transference changes a bit with frequency.
