Is photography good for primary composition or secondary composition?

The so-called secondary composition is to cut off the original film, which is chaotic and has nothing to do with the theme. This is a remedy and an immature ingredient.

Secondary composition is also a kind of re-creation, which can remove the original wrong things, re-express the theme or express a new theme.

Cropping will lose pixels and make the photo smaller.

Documentary photography, due to various situations, emergencies are fleeting, and photographers have to consider composition and exposure. Often improvise and have no time to think. This kind of film is excusable for a second creation. Such as wedding dresses, advertisements, artistic photography, landscapes, etc. It is best not to write a second composition.
