“Negative space isn’t the absence of space but rather the space that defines the positive space.” [link]
This is my Aunt Bibi’s bird. It’s all about negative space. The sweep of the neck and the curve of the back enhance image.
As a former scientist, I’m fascinated with biological design and tend to do a lot of macro photography. For macro shots, there’s a trade off between zooming in for detail and zooming out to improve the composition of the picture. I posted this flower a couple weeks ago. The close up (with minimal negative space) shows textures and the play of light through the petals.
Backing off the flower increases the negative space and gives a sense of the wider world of the garden.
It's a trade off.
