What happens after rendering?

Could you please elaborate on what occurs following the rendering process? I'm quite curious to know the subsequent steps involved and how they contribute to the overall outcome. Does the rendered image undergo any further modifications or enhancements? Are there any specific checks or validations that take place? I'm also interested in understanding how the rendering phase fits into the broader workflow of the project. Could you provide some insights into the sequence of events that follow rendering and their significance in the overall process?
