The difference between apple camera portrait and photo.

The difference between Apple camera portrait and photo: portrait will be clearer.

Both iPhone 12 and iPhone 12 mini have dual-lens cameras, and the camera technology is the main difference between the iPhone series standard models and the iPhone 12 Pro models.

There is a super wide-angle camera with12 million pixels, f/2.4 aperture, 120 degree field of view and 13mm focal length, which is very suitable for landscape shooting and unique artistic shooting with super wide-angle field of view. Apple has added a lens correction function to eliminate any distortion caused by super wide angle.

The ultra-wide camera comes with a standard12 million pixel wide camera with a focal length of 26mm and an aperture of f/ 1.6, which is 27% more than the aperture of f/1camera of iPhone1.8. This is a new 7-element lens, which is an upgraded version of iPhone 1 1 medium12 megapixel lens.

IPhone 12 Pro also has wide-angle and ultra-wide-angle cameras, and the third telephoto lens that iPhone12 lacks. In addition, iPhone 12 model supports 5x digital zoom and 2x optical zoom (using super wide-angle lens), but does not support optical magnification, which is a disadvantage.

A camera is a kind of equipment that uses the principle of optical imaging to form an image and records the image with a negative. This is an optical instrument used for photography. In modern social life, there are many devices that can record images, all of which have the characteristics of cameras, such as medical imaging equipment and astronomical observation equipment.

After the light reflected by the shot scene is focused by the camera lens and the shutter that controls the exposure, the shot scene forms a latent image on the photosensitive material in the camera box, and forms a permanent image after being developed and fixed. This technology is called photography, which is divided into general photography and professional photography.

The earliest camera structure was very simple, including only a black box, a lens and photosensitive materials. Modern cameras are complex, including lens, aperture, shutter, ranging, framing, photometry, film transmission, counting, self-timer, focusing, zooming and other systems. Modern camera is a complex product integrating optics, precision machinery, electronic technology and chemistry.

1550, Italian cardano put the lenticular lens in the original pinhole position, and the image effect is brighter and clearer than the black box.

1558, the Italian Barbaro added an aperture to the device in cardano, which greatly improved the imaging clarity. 1665, John Zhang, a German monk, designed and made a small portable single-lens reflex camera box, which could only be used for painting because there was no photosensitive material at that time.
