Why is the location wedding photo taken by the studio so clear without processing? I can't get the same effect with the same machine. How did they adjust?

Generally speaking, there are two aspects.

1, parameter setting

Saturation, chroma, clarity, etc.

2.ISO settings

Set the sensitivity of coms element. The lower the sensitivity, the higher the definition.

3. Aperture control

Is to control the amount of light, the greater the amount of light, the better the gray level, but easy to expose. In this way, it is a difficult problem to determine the light environment and maximize the aperture.

These are roughly the aspects.
