During this photo I was going for a cool harmony but my camera was focusing and blurred the background and the gray/brown neutral colors really stood out with my tan waterbottle. So after seeing that I began taking photos for a neautral harmony which I intinaily planned too.
I like this photo because the sky is a perfect balance between the red boat and blue water, and ther are all part of the same section of the color wheel making this analogous.
I was out on a run, and saw this toy truck that reminded me of a toy I had when I was young and sent a picture of it to my grandma to remind her. Then I noticed I like the leading lines next to it and took a couple of more to get this cool harmony photo.
