• Count - A function used to count the cells with content in a range.
• Sum - A function used to compute the summation of the number of a range
• • Average - A function used to compute the average of the number of a range.
• • COUNTIF - a function used to count the cells with a specified content within a range.
• • SUMIF - A function used to compute for the summation of a range if a certain condition is met.
• • AVERAGEIF - A function used to compute for the average of a range if a certain condition is met.
• • RANGE - The range of cells where you want to look for the criteria.
• • CRITERIA - Defines the condition that tells the function which cells to count.
• Balance in design is the distribution of the visual weight of objects, colors, texture, and space, making a design feel stable.
• Symmetrical balance in design is when the elements used on one side of the design are similar to those on the other side.
• Asymmetrical balance in design is when the sides are different but still look balanced.
• Radial balance in design is when the elements are arranged around a central point and may be similar.
• Emphasis in design is a concept that involves giving special attention to a specific element or area within a design.
• Contrast in design is one of the techniques used to achieve emphasis.
• Movement in design is the path the viewer’s eye takes through the work of art, often to focal areas.
• Pattern in design is the repeating of an object or symbol all over the work of art, creating a group of elements or motifs that repeat in a recurring and predictable manner.
• Repetition in design is the use of repeating design elements (colors, shapes, patterns) throughout a graphic to create consistency and reinforce branding.
• Unity in design is the feeling of unity created when all parts (sizes, amounts, or numbers) relate well with each other.
• Proportion in design is the feeling of unity created when all parts (sizes, amounts, or numbers) relate well with each other.
• Rhythm in design is created when one or more elements of design are used repeatedly to create a feeling of organized movement.
• Rhythm in design creates a mood like music or dancing.
• Rhythm in design can be achieved through the arrangement of elements and use of lines or patterns.
• Harmony in design is about ensuring that elements complement each other and create a pleasing balance between different visual aspects like color, shape, size, and spacing.
• Changing Background in image manipulation involves replacing the original background of an image with a different one, commonly used to alter the environment or setting in a photograph, creating a new context or mood.
• Compression in image manipulation is the process of reducing the file size of an image while attempting to maintain acceptable image quality.
• Cloning in image manipulation is the process of duplicating or copying a specific area or object within an image and then pasting that duplicate in another part of the image.
• Variety in design is the use of several elements to hold the viewer's attention and guide the viewer's eye through and around the work of art.
• Unity in design refers to the overall sense of oneness and coherence in a design, creating a sense of completeness and ensuring that everything in the design looks like it belongs and fits well together.
• Color Balance in image manipulation is the adjustment of colors within an image to ensure that they appear accurate, natural, and visually pleasing, considering factors like the ambiance and the tone of light of the picture (e.g., warm or cool light).
• Cropping in image manipulation is the process of removing a portion of an image to frame or focus on a specific area or subject within it, used to eliminate unwanted or extraneous parts of an image and highlight the desired content.
• Filters in image manipulation refer to predefined image processing effects or adjustments that can be applied to an image to change its appearance, often used to enhance, stylize, or transform images in various ways.
• Brightness and Contrast in image manipulation allow you to control the overall luminance (brightness) and the differentiation between light and dark areas (contrast) in an image.
• Resizing an image involves changing its dimensions, either by making it larger or smaller.
