I hate straight lines. They are boring, plain, uninteresting and over rated. They route you in one side of a scene or picture, and then right out the other.
Just look at our buildings. For the most part they are boxes. And why; I suspect that in part it is dictated by custom, materials at hand and familiarity. And or possibly a lack of imagination.
Don’t get me wrong, straight has its place. It is just that it is highly overrated, overused and unimagetive.
The eye loves round. It softens a shape, it flows and allows the eye to dwell in one space. It can linger and rest there. It can reside in one spot and refuse to leave. Just gaze around you in Nature. Straight is highly outnumbered by well rounded lines. Take the time to observe and you will find it relaxing and rewarding.
Look at these two top pics and notice how the eye automatically follows the curve of the water and the path. You are lead into the scene and wonder what lays around the bend.
When you look at these pics, the eye wants to dwell there and check out all the details.
Arches, domes, and many other curved structures of the past still abound today due to their strength, endurance, and design. Take a tour of Europe or Asia and many of these features will be evident. They will leave you in awe and wonderment as to their durability. Cheers.
