One of my favourite places to photograph is along the Grand Canal in Dublin's city centre. I used to work near there and I used to pass it every day on my way two and from work. I've shot lots of photos there over the years and it's great for capturing everything from nature (by the side of the canal) to urban decay (some of the graffiti either side of it) to even street photography as people walk to and from their work to the tram stop nearby.
There's a stretch of walkway that runs along by the canal that has a regular metal railing. The position of this fence is such that in the morning, when the sun is shining you get really strong shadows of the bars on the bright concrete slabs that make up the walkway. It's great for taking abstract shots, even if it is a bit of a cliché. I was passing by the walkway earlier today, and it was a beautiful bright sunny day, and the shadows were particularly strong, so I thought I'd have a bit of fun with the shadows and see what interesting shapes I could capture with the parallel and diagonal lines.
All of these were shot on the iPhone and edited using VSCO Cam.
