What do you think is meant by “Abstract photography” can be defined as capturing images in which the subject isn’t the most interesting element”?

I believe this statement means how abstract photography could be taking photographs of anything around you using the help of a variety of different abstract materials. In other words, meaning how the original subject of the photo may not be the most interesting element but abstract photographers are able to use perspective, movement, and light to transform the world we see into an unexpected, often unrecognizable image, which adds a layer of mystery and deeper meanings presented to the audience.
