The camera takes a macro shot of reflective objects, such as an egg-shaped polished surface. Sometimes there seems to be a layer of fog on the surface of the photo (the surface is not very clear and sharp). Is this the diffraction of the light source? Non-metal can be equipped with polarizer to eliminate reflection, and metal must adjust the angle of light source until the reflection seen in eyepiece is acceptable for shooting (including tinfoil and other items).

A layer of fog can't be judged to be caused by reflection. The so-called reflection is the appearance of extremely high aurora (if the light ratio is too large, the dark part will be accurately exposed, and the highlight is dead white, so there should be no fog feeling) and the unnecessary reflection image will be reflected. Only in this way can you adjust the light distribution or add polarizers.

The foggy feeling is mostly because the light ratio is small, which just shows that the exposure is accurate and should be a good film. There is no built-in post-major, even if some curves are built-in, they are general curves implanted for in-machine conversion to JPG (you can download the curves and implant them yourself if you want to go straight out, but it is not recommended to go straight out for the product piece). When shooting products with professional cameras, RAW files must be output and post-processed in professional software (mostly PS) to get the desired effect.
