In approaching this project I have tried to find 4 very different curved lines formed in distinctive ways. The first image is a street light found on Ludwig Strasse in Munich. Trying a few different angles, I found that the backlit image below had the strongest impact as only the outline of the street light is visible emphasizing the shape rather than any detail
5D2, 400mm, f/5.6, 1/8000, ISO 800
The next image is quite the opposite, strongly lit it emphases the contrast of the terracotta tiles with the blue sky in the background, but also reflected in the circular skylight. An example of a curve used in architecture
5D2, 300mm, f/4, 1/1000, ISO 100
The third image comprises two separate curves, both formed partly by nature and partly by design. The jets from the fountain are curving over as gravity pulls the water into a parabolic curve. The spray from a larger water jet, just out of frame, is catching the late afternoon sun and casting a rainbow as the light is diffracted by the water.

My final image is a natural wooded scene with a sinuous S curve snaking through it, a picture of harmony. Not quite true, the path has been created through the forest to provide excitement for the local kids riding their mountain bikes at great speed down the hill. Impressive to watch, but not very peaceful, particularly if you do not know what the intent is. This image is compositionally balanced, but I find it rather flat, I suspect it would be better photographed with stronger sunlight to produce stronger shadows and bring out the shapes

Whilst working on this project I took quite a few images in the subway system where the tunnels force the use of curves in much of the construction. I am thinking about using the subway system as a subject for one of the assignments later in the course and so whilst I was not happy with the images for this project I keeping this in mind for later. Here are a few images
One aspect of curves that I did not use in this project was the human body, I think this would work well, but the images would need careful planning and lighting, so perhaps not ideal for this current activity.
