I feel like high key is full of light, low key is full of dark for a picture.

This is high key because the background is bright and the light is on the fork. The first thing I saw in this pic is the bright spot on the fork.

This is a pic of a recycle box when I zoom in, I feel like this pic is low key because the pic is almost full of black. There are only two color in the pic and the black is about 80% and the white is about 20%.
