How to remove burrs in photography

First of all, I am not an expert, but an amateur. I hope my nonsense is useful to you.

Have you ever heard of the phrase "make up the deficiency in advance"? This is a common photography method, especially commercial photography.

First of all, in terms of color, the first and third photos are comfortable but distorted, so I judge that these two photos are post-processed. If you want to know whether your Sony camera can directly capture this effect, I find it difficult.

The second and fourth pictures have also been retouched, but only the saturation and sharpness have been enhanced, and the grinding sample of the original film has been basically maintained, so it gives people a stiff feeling.

Nowadays, camera manufacturers are trying their best to make their cameras have higher definition and more restored colors. If the photos come out like the first and third photos, they will become beautiful artifacts.

Don't doubt that Lycra and Sony will be very different in photos. The quality of photos depends largely on people and your understanding of good photos and beauty.

The picture below was taken by the Leica camera I found online. How do you feel about your Sony compared with yours?
