What is commercial photography? People who haven't studied photography may not know. What's the difference between commercial photography and ordinary photography? Let me briefly introduce what commercial photography is to you.

The definition of commercial photography

Commercial photography, also known as entrusted photography, refers to photography activities for commercial purposes. In a broad sense, it includes the production of all images used to sell goods, write events or introduce books, while in a narrow sense, commercial photography usually refers to advertising photography, not only because advertising photography plays an important role in it, but also because of its natural and strong commercial color. In commercial photography, the photographer's photography technology and aesthetics are the key, but without the promotion of shooting concept and management concept, the photos taken are just a bunch of useless films for the parties.

Noun interpretation

At present, the common commercial photography has been divided into fine categories, such as full-time car photographers, people photographers, digital product photographers, cosmetics photographers and so on. , is an indispensable part of the fashion field.

Commercial photography, also known as commissioned photography, was despised in early years. However, as the backbone of applied photography, it has always inspired pioneers to make unremitting efforts to develop new technologies and broaden the artistic field.

In modern times, the cooperation between commercial photography and commercial photo library is a common mode. The photo library will entrust photographers to create photos of a certain theme or commercial photographers to upload their own photos on their own initiative and entrust the photo library to act as an agent. With the advent of the photography era, the role of commercial photography has become more and more prominent, and many commercial photography photo agencies have appeared in China, such as Dajue Color Photography, Oriental IC, IC Creative, 8-unit Photography Network, and Tuwei Media.

Domain characteristics

/commercial photography covers a wide range, even in various industries. Among them, the most obvious commercial photography is product photography, advertising photography, portrait photography, studio photography and other photography works with commercial value, including aviation and space. Moreover, many freelance photographers sell photos as commodities, and many photo agencies sell the photos they buy to people in need.

Now that we know the scope of commercial photography, we should understand the differences between them and master their characteristics.

The photographic characteristics of products are mainly manifested in the photography with products as the main genre. Their photos are used in advertisements, commodities, catalogues, product brochures, pamphlets and similar publications. They are also used for packaging and decoration of posters and exhibition brochures, as well as packaging bags and boxes. The photos introducing the product must be clear and straightforward, and the color, shape, material and structure of the product should be reproduced. Photos used for promotion usually beautify products and give people a hint that they can provide tangible and intangible benefits, which are generally expressed by images.

Most products are photographed in the studio, because the lighting conditions in the studio are completely controllable, and some photos of products are taken on the spot, for example, large products are not easy to move because they need a certain environment. Generally speaking, most of them are done indoors. Photographers of product photography always make a good design in advance, and then complete it according to the artistic guidance of design. Sometimes this design may be a sketch, or a wonderful picture, and then a comprehensive explanation draft. It should be said that product photography is only a kind of still life photography of the product itself. Product photography may use a variety of light sources, and the effect can be continuously tested. As for the quality of shooting, success or failure depends entirely on the photographer's level.

Matters needing attention in commercial photography

As we all know, if a worker wants to do a good job, he must sharpen his tools first. The influence of high-quality equipment on the quality of commercial photography is self-evident, but the important thing is whether you will stick to your choice principle in the face of the high price of high-quality equipment.

Choose a movie

Film is the carrier of images, and its quality directly affects the quality of commercial photographic images. As far as film sensitivity is concerned, because film sensitivity has a certain internal relationship with film's performance such as contrast, latitude, granularity, resolution, haze and preservation, low-sensitivity films have obvious advantages in granularity, resolution and haze, so try to choose low-sensitivity films.

exhaust

Light has two basic functions in commercial photography: one is to make the film sensitive; The second is to make the subject produce different shapes, colors and texture effects. In black and white photography, light is both an energy and a strength. You must know it well to control the shape, texture, tone and artistic conception of the photo. Creative use of light will make ordinary subjects have extraordinary effects!

glass filter

Because commercial photographic filters have different absorption and passing effects on different colors of light, they can effectively improve the contrast and tone of the image and better represent the level of the subject. In the choice of filter screen, we must first choose high-quality filter screen. Because the filter, like the lens, is directly related to the imaging quality. The combination of inferior filters and high-quality lenses is simply a waste of expensive high-quality lenses!

Mood expression

Tone is to commercial photography what tone is to music. Tone has a strong emotional expression, and the lightness or dullness, roughness or delicacy, lightness or depression of black and white commercial photography works are often caused by the tone effect of the picture. In timbre control, learning to imagine is the most important. In black and white photography, any color is abstracted into three tones: black, white and gray. In the process of abstraction, if you don't give full play to your imagination, there is no way to control and express your tone. Of course, for the performance of commercial photography tone, necessary technical measures must be taken, such as the selection of light, intentional overexposure or underexposure, the use of filters, etc., which can all play a role in adjusting tone.

{Photography} Classic photos, don't you need PS for post-production? A business photo is a business photo. Don't tell me that business photos are classics. Classic photos have commercial value, but pure commercial photos are not qualified to judge classics. Commercial photography is aimed at making money. What is the qualification of photography for the purpose of exchanging money compared with the photos bought by those war photographers with their lives?

In a word, there are no classics in commercial photography. Chen Man's photography is commercial photography, not classic photography. No matter how good her lighting and composition are, she can't compare with the fake and inaccurate photo of Capa.

Classic photos can be PS, but they are all PS in color and level, and the skeleton structure of some photos should not be PS.
