Composition: The placement or arrangement of visual elements or ingredients
Layers: Photoshop layers are like tracing sheets. You can see through transparent areas of a layer to the layers below. You move a layer to position the content on the layer, like sliding a tracing sheet in a stack. You can also change the opacity of a layer to make content partially transparent.
.PNG: PNG (Portrable Network Graphics) is a image file format that has a transparent background.
.PSD: Photoshop Document is the default format that Photoshop uses for saving data. This allows you to save your work to keep working on for later.
.JPEG/.JPG: JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.
.GIF: a movin image.
Gradient: A gradual change in color from one tone into another. Two common types of gradients are the linear gradient where each color sits on opposite sides of the frame, and a radial gradient where one color sits in the middle, and another at the edge.
Alignment: The lining up of elements to achieve balance, order, and a more logical layout. There are also four common types of typographical alignment – center, left, right, and justified, each with their own time and place for application.
Opacity: The degree of transparency an element has. The lower the opacity, the more transparent an element is.
Resolution: The amount of detail an image has. Generally speaking, the higher your resolution, the better your images appear, and the more detail is rendered. Whereas lower resolution images or graphic tend to appear blurry, pixelated or muddy.
Contrast: The degree of difference between two juxtaposed elements. Some other common types of contrast are dark vs. light, thick vs. thin, rough vs. smooth, etc.
Saturation: The degree of intensity and vividness of a color. For example, a low-saturation color may appear pale and faded, whereas a more heavily saturated color may appear more vibrant and colorful.
Rule of thirds: Rule of Thirds is a theory that if you divide your image with two vertical and two horizontal lines, the areas where your lines intersect will become focal points of your design.
Scale: The change of size of an object while keeping its shape and proportions intact. Large scale can create drama, and smaller scale can create fine detail.
Razter: Raster images, are comprised of individual pixels of color.
Vector: Vector graphics are made up of paths, each with a mathematical formula (vector) that tells the path how it is shaped and what color it is bordered with or filled by.
Typography: The artistic arrangement of type in a readable and visually appealing way. Typography usually concerns the design and use of various typefaces in a way that helps to better visually communicate ideas.
Display Type: Type that is designed with the objective of attracting attention. Think of movie titles on posters, article titles in magazines, newspaper headlines, etc
Hierarchy: The visual arrangement of design elements in a way that signifies importance. For example, you might make a title big and bold to ensure it attracts more attention than a small, lightly colored image caption.
