Is there any difference between a commercial photographer and a portrait photographer?

Whether it's good or not depends on your opinion. There is no distinction between good and bad.

As far as I understand it, let me talk about their characteristics:

First of all, commercial photography is a relatively high threshold in photography. Generally speaking, photography skills without a few years or even 10 years are not qualified for this job.

Secondly, commercial photographers are not only photographers, but also top digital engineers. They can also be called retouchers or artists, and they need to be proficient in PS, LR and other software.

The equipment in the field of commercial photography is also more complicated and expensive than general photography. Because you have to shoot all kinds of big themes often, you have higher requirements for pictures and pixels. Cameras usually use Quan Huafu or even medium format, and the lowest is Quan Huafu. The relatively high-end cameras are basically medium format cameras with pixels around 5000W W W.

Let's talk about portrait photographers first:

1. Portrait photographer is also a kind of commercial photography, which is equivalent to subdivision. The photographic equipment is basically Canon, the better one is 5D3 or 1DX, and the lenses are mostly fixed focus. Not as complicated as the scene of commercial photography.
