Technology-based art uses computers and digital tools to create and manipulate images rather than traditional materials like paint and brushes. It includes digital photography, digital painting, computer-generated images, and videos created on computers, phones, or tablets. Many popular apps allow artists to edit photos, create collages, add effects, and combine images and text on a range of devices. Computer-generated images are now very common due to widespread computer use, though minor edits to images may not qualify them as fully computer-generated. Digital photography also allows various points of view and techniques like using the rule of thirds.
