Understanding Digital Image Files
Digital image files are files that contain digital representations of images. These files can be created using various devices, such as cameras, scanners, and smartphones. The primary purpose of these files is to store, transmit, and display images in a digital format.
When you capture an image using a camera or smartphone, the device converts the light that enters the lens into a digital signal. This signal is then processed and saved as a digital image file. These files can be stored on various devices, such as computers, smartphones, and external hard drives.
