I hired a photographer. He said three points for photography and seven points for later.

Just comparing the previous works with the post-processing works with the naked eye, you may have the above idea.

But apart from what you see on the surface, the work done in the early stage is largely to pave the way for the later stage.

Give the simplest example:

Pre-exposure: slight overexposure. After the adjustment, many people may think: thanks to the adjustment.

In fact: the photographer deliberately overexposed, because in the digital age, especially Canon's cameras, the color below neutral gray will be very dirty. Expose it to the right as far as possible under the acceptable premise, and then pull it back later. This is a more reliable way.

Therefore, individuals can only say that the late stage and the early stage together constitute photography, which is equally important and inseparable.

Every reliable photographer should be based on: do better in the early stage and save effort in the later stage.

Most of the late dependence is irresponsible and inefficient.

In addition, your question below refers to still life photography. If I regard it as advertising photography, this category has a larger proportion than any other category in the early stage.

Apart from some creative elements, it can be said that 80% of them are based on careful work in the early stage. Very time-consuming and labor-intensive.
