Is photography an additive art?

Photography is an art and has nothing to do with addition and subtraction.

Introduction to photography: The word photography comes from Greek Φ Φ Φ Phos (light) and γ ρ α γραχgraphics (painting and sketch) or γ ρ α η graph η, which together means "painting with light". Refers to the process of recording images with some special equipment. Generally, we take pictures with mechanical cameras or digital cameras.

Sometimes photography is also called photography, that is, the process of exposing the photosensitive medium by using the light reflected by the object. Someone once said an incisive language: the photographer's ability is to transform the fleeting ordinary things in daily life into immortal visual images.

Photography, commonly known as photography, is to use a camera to image the negative, and print the negative into a single photo, which is permanently preserved one by one. But the image of the photo is static and silent, just to let people watch its characters and artistic conception, and then understand its meaning. Today, the earliest existing photos in the world can be traced back to 1827, which was taken by the Frenchman Joseph Nipps.

Generally speaking, people take pictures with visible light, and cameras are the most commonly used. Because of different scenes and uses, cameras have many classifications. Generally speaking, a camera must have several basic components to ensure the exposure process, including: photosensitive medium, imaging lens, exposure time control mechanism, film cassette and storage medium.
