How do photographers make profits for themselves?

I've heard that some people keep investing money, time and energy in pursuit of photography, asking for nothing in return, or even losing everything, and their wives and children live apart. However, social understanding is often called "dedication to art". Photographers are "edified" in this traditional atmosphere, which leads to the opposite understanding of "art" and "money" and the distorted concept, as if they are "real artists" only if they don't ask for anything in return and don't talk about economy. In fact, this idealized "real artist" is extremely rare. I believe that most photographers want their photos to be elegant when they have a "fever" to a certain extent. As you can imagine, you must feel very proud when your photos are made public by the media. Although hobbies don't necessarily depend on photography for a living, it's not a bad thing to cultivate hobbies through "photography" and earn income by submitting articles or participating in photography competitions. Why not create value for society and wealth for yourself? Agents sell photos, and the photos that can be sold are not necessarily top photos, but at least they are good photos that conform to the "three principles". It also depends on market demand. It is said that there are too many photos of human landscape in the photo market, which is almost saturated, while creative portraits are better to sell. The so-called creativity is not necessarily a unique perspective. Sometimes a chair or a window is a good theme. As commercial advertising material, this kind of picture requires uniform and flat lighting. Of course, if you want to shoot a creative portrait, you need to pay a model fee to hire a model. I guess it was difficult at first. If you pay more attention to the things around you and shoot people and things around you, it is still possible to raise your hobbies with photography. Let's say it's better to take "photography" as a hobby or take part in a local photography competition. If the property needs to be promoted, photographers' associations should be invited to assist in the photo contest. The first prize is 3000.00 to 5000.00, and the finalist prize is 50.00 to 100.00. Further emancipate the mind and renew ideas. As long as you are willing to spend more time in competitions, you will have a chance to create benefits. Let photographers know how to use photography to cultivate their hobbies instead of burning money and poisoning blindly.
