Do you have to save photos when taking photos with a camera 1 years ago?

you must. 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. It is an optical instrument used for photography. Ten years ago, there was no printing technology without saving, so it was necessary to save and print at the place where the photos were printed. The earliest camera structure was very simple, including only the black box, lens and photosensitive materials.
