Ootdty Door Lid Cover Case For Nikon D50 D70 D80 D90

Digital Still Camera (DSC), abbreviated as Digital Camera (DC), is the abbreviation of digital camera, also known as Digital Camera. A digital camera is a camera that uses electronic sensors to convert optical images into electronic data.
Classified by purpose: DSLR cameras, mirrorless cameras, card cameras, telephoto cameras, and home cameras. The principle of using chemical changes of silver bromide to record images on film is different between digital cameras and ordinary cameras. The sensor of digital cameras is a photosensitive charge coupled device (CCD) or complementary metal oxide semiconductor (CMOS). Before transferring images to a computer, they are usually stored in digital storage devices (usually using flash memory; floppy disks and rewritable discs (CD-RW) are rarely used in digital camera devices).
Digital cameras are products that integrate optics, mechanics, and electronics. It integrates components such as image information conversion, storage, and transmission, with digital access mode, interactive processing with computers, and real-time shooting characteristics. Light enters the camera through the lens or lens assembly, and is converted into digital signals through digital camera imaging components. The digital signals are stored in storage devices through image processing chips. The imaging element of a digital camera is CCD or CMOS. The characteristic of this imaging element is that when light passes through, it can be converted into electronic signals according to the different types of light. Digital cameras first appeared in the United States. More than 20 years ago, the United States used them to transmit photos to the ground through satellites. Later, digital photography became civilian and continuously expanded its application range.
advantage
1. After taking a photo, you can immediately see the image, which provides the possibility of immediately retaking unsatisfactory works and reduces the occurrence of regrets.
2. Just pay for the photos you want to develop, and other unwanted photos can be deleted.
3. Color restoration and color range no longer rely on the quality of the film.
4. The sensitivity is no longer fixed by the film, and the photoelectric conversion can provide multiple sensitivity options.
5. The product structure is relatively simple, the appearance is more exquisite, and the product is becoming more and more portable.
6. The operation of digital cameras is simple, clear, and easy to get started with.
shortcoming
1. Due to the conversion between imaging components and image processing chips, the imaging quality lacks a sense of hierarchy compared to optical cameras.
2. Due to the different image processing technologies of various manufacturers, the colors displayed in imaging photos may differ from the actual objects.
3. The maintenance cost is relatively high.
