In this image there are a few horizontal lines. The obvious one is the coastline towards the back of the image but there is also a line suggested by the boats in two rows.
Here there is one strong vertical line. It divides the frame in 2 down the middle and has an overpowering sense giving the image an uneasy feel.
This image feels more balanced than the last with lines formed by the fork.
Here another vertical line in the form of a shadow. The composition here feels more balanced than the last vertical.
Here horizontal lines suggested by the horizon and shorelines.
Horizontal lines here are actually 'lines' of text. They work well to lead your eye to the in focus text.
Here there are many vertical lines formed by the tree trunks. The two main trunks balance the image by being on thirds.
Another strong vertical line here separates the frame in 2. This has the same effect as mentioned previously.
