End result

Image or screen detail is quantified by resolution. Higher resolution results in clearer and more detailed images. Pictures displayed on a screen are measured in pixels per inch (ppi), whereas those printed off are measured in dots per inch (dpi). Because higher resolution results in smaller pixels, more information may be displayed per unit area. The picture is clearer and more precise.

Shade Progression

A picture’s or monitor’s color depth dictates the number of colors it can display. Limited color depths of 8 or 16 bits give images a grainy appearance. With 24 or 32 bits, millions of colors are used to create photorealistic visuals that are smooth. Subtle changes are achieved by using more colors.

Formats for Files

Regarding picture quality and file size, every file format for archiving and compressing digital photos has its advantages and disadvantages. Some examples of image formats are JPG, PNG, and TIFF. Many people use EPS, PDF, and AI as their print styles. A few examples of good web graphics are GIF and SVG. Pick a format that works with images.

Animation

Animation on a computer typically consists of a rapid succession of still images, or frames. Gradual frame shifts are used to represent movement in basic animation. Keyframes, tweening, and motion pathways are the building blocks of complex animation, which generates realistic effects and motion. Many fields use animation, including media, education, entertainment, science, and more.

Learn the fundamentals of computer graphics, including how to work with animation, color depth, file formats, and resolution. Advanced modeling, rendering, and picture editing skills will be yours to acquire thereafter. The options are endless!
