How to paraphrase these sentences?

There are prominent circles of confusion and halation around highlights or light-valued areas of objects in front of the principal plane of focus. The effect of a principal plane of focus on the formation of circles of confusion is conspicuous in the treatment of the chandelier in A Painter in His Studio; here the circles of confusion become extremely large in contrast to the much smaller circle formed at the far wall which defines that principal plane. The highlights spread into small circle, and in such images the solidity of the form of a barge for example is disintegrated in a way that is very close to the well-known effect of light reflected as a point from an object in nature pes through a lens and is not revolved.
