Future Prospect of Photography Technology

Photography, usually called photography, uses a camera as a tool to draw pictures with light. A camera is a photographer's creative tool. Photography is essentially a collection of technology and visual observation, and it is a combination of technology and art. Traditional photography refers to a photography method with traditional cameras and films as its main features, which is to take pictures and develop them in a dark room. Traditional photography is a photochemical process. Images are stored on film in order to preserve the photographic effect with negative film. Traditional photography has gone through a long historical process.

Digital photography refers to a new type of photography characterized by a digital camera, which is shot with a digital camera, processed by a computer, and then output with printing equipment or digital color printing equipment. He is a revolution in photography technology and tools. A new method of recording, storing, processing and transmitting visual images by electronic means instead of traditional chemical media.

From the original pinhole camera to the professional digital SLR camera, it has experienced a historical change of nearly 170 years. Modern cameras widely use high technology, which greatly simplifies the operation of photography technology. With the improvement of people's material and cultural life, cameras have entered thousands of households, and "being able to take pictures" has become people's demand and fashion, just like "being able to surf the Internet". At present, the world is in the era of information explosion, and graphic information has the characteristics of image, intuition and vividness, and its role in production and life is no less than that of text symbols. Today's world is also called "the era of reading pictures". Langford, a British photographer and educator, once predicted: "Photography will be as profound as words or music sooner or later, and become an art for people to express their thoughts.

Compared with traditional photography, modern digital photography has undergone earth-shaking changes. The process of digital photography is very similar to traditional photography. Cameras are used to capture images, but negatives are replaced by a magnetic storage device, such as a hard disk or a magnetic disk on a computer. The reason why digital photography almost replaces traditional photography lies in its advantages: from the cost point of view, digital cameras do not need to spend extra money to take pictures, and they can be used repeatedly after purchasing digital cameras, memory cards and batteries. In terms of quality: the images obtained by digital cameras exist in digital form and can be transmitted by various devices. There are many applications in the world today, and there is no loss of image quality during transmission. In terms of operation: the digital camera can immediately see your photos on the display screen. When the effect is not good, you can take another photo, leaving only the photo you like and deleting other photos. In terms of preservation and arrangement: digital camera photo backup is extremely simple, and photos can be copied to CD. A CD can store thousands of photos, and photos can also be placed in various free homepage spaces. It is very simple to organize, store and find photos by digital means. Put them in the computer, so that you can see hundreds of photos displayed as thumbnails at a time in the simplest way, and you can find the photos you want immediately. In terms of * * * enjoyment and transmission: digital photos can be directly sent to friends and customers by e-mail, or directly placed on the web page. When traveling, if you want to send photos home, you just need to find a computer, download photos from the camera and send them to friends and family by email.

Although modern digital photography has made great progress and breakthrough, its development prospect is still very broad. Now we look forward to the development and prospect of digital photography.

Perfect combination of digital photography and computer: If photographers are computer experts or professionals, they have a unique technical advantage in using digital cameras. On the computer, you can do whatever you want.

Processing digital photos, browsing, enlarging, reducing, copying and deleting points at will, and learning a little image processing software, such as Ps and AI, can easily handle the brightness, contrast and cropping of photos, and beautify and repair photos. Nowadays, wedding photography basically uses computers to process digital photos. This will be the future development direction, using special software to process digital photos.

Micro hard disk storage:

Just as the floppy disk of personal computer is replaced by U disk, it is also a development trend that the memory card of digital camera is replaced by micro hard disk with larger storage capacity.

There are two core imaging components of digital cameras: one is widely used CCD (Charge Coupled Device); Charge coupled element; The other is CMOS (complementary metal oxide conductor) element. Their function in digital cameras is to convert the optical signals of images into electrical signals, register them separately, transmit them under the action of external scanning signals, and finally convert them into electronic files of images through various operations. The advantage of CCD lies in its good imaging quality. However, due to the complex manufacturing process, only a few manufacturers can master it, which leads to high manufacturing cost, especially for large CCD. . 、

The color reproduction of digital camera is completely based on the designer's software programming method to simulate the original scene information. CCD image sensor uses photosensitive unit to receive light, but it has no ability to identify the color of light (if a new photoelectric sensing device can be used to detect the wavelength and intensity of light, then the digital camera will be completely transformed).
