Even though digital images are rendered using an ideal thin lens, people often go back and add artifacts associated with real lenses (lens flares, chromatic aberration, bloom, etc.). Would this make the image seem more realistic to us, since it would more closely resemble an actual photograph? I wonder if most people would actually prefer an image from a real lens to an image generated using thin lens mathematics, since these small imperfections are likely why a lot of people prefer photos taken by old vintage cameras to cleaner photos taken by digital cameras.

From this slide, we see that real lenses are complex, consisting of multiple optical elements and are designed to correct for various aberrations. However, they can't converge light rays perfectly due to imperfections. In contrast, ideal thin lenses are a theoretical construct that simplifies calculations by assuming that all rays refract at a single plane and converge to a single point, which helps us quickly understand the basic principles of imaging. This side-by-side comparison is crucial for understanding why lenses behave the way they do in real-world scenarios versus ideal conditions.
