Digital Media Quiz - Scanning, Colour And Resolution

Monitors use RGB (Red, Green, Blue) as a color system because they emit light to produce colors. RGB is an additive color model where different combinations of red, green, and blue light create a wide range of colors. Each pixel on a monitor is composed of three subpixels, one for each primary color, and by varying the intensity of each subpixel, the monitor can display different colors. This is why RGB is the standard color system for monitors and other electronic displays.

The term RGB stands for Red Green Blue. It is a color model used in digital imaging and computer graphics, where colors are created by combining different intensities of red, green, and blue light. This model is widely used in electronic displays, such as computer monitors and televisions, as well as in digital cameras and image editing software. By adjusting the intensity of each primary color, a wide range of colors can be achieved, allowing for the accurate representation of images and videos on digital devices.

When two primary colors are mixed together, they create a secondary color. Primary colors are red, blue, and yellow, and when combined in different proportions, they produce secondary colors such as green, purple, and orange. This is because primary colors are the basic building blocks of color, and by mixing them, we can create a wider range of colors. Therefore, the correct answer is a secondary color.

PPI stands for "Pixels per inch." It is a measurement used to describe the pixel density of a display device, such as a monitor or a smartphone screen. PPI indicates the number of pixels that are packed into one inch of the screen's real estate. A higher PPI value generally means a sharper and more detailed image, as there are more pixels available to display the content.

The correct answer is "All of the above" because the question lists three types of scanners: sheet-fed, drum, and sheet-fed. Therefore, the correct answer is that all three types mentioned are types of scanners.

Warm colors, such as red, orange, and yellow, are often associated with high energy, excitement, and intensity. These colors tend to grab attention and create a sense of urgency. They can evoke strong emotions like passion, anger, and enthusiasm. In this context, "aggressive" refers to the bold and assertive nature of warm colors. Therefore, the statement "Warm colors are aggressive" is true as warm colors have a tendency to create a strong visual impact and convey a sense of aggressiveness or intensity.

The three primary colors are red, yellow, and blue. These colors are considered primary because they cannot be created by mixing other colors together. Instead, all other colors can be created by combining different proportions of these three primary colors. This concept is commonly used in art, design, and color theory.

TIFF (Tagged Image File Format) is indeed mostly used for large format print images. This file format supports lossless compression, which means that the image quality is not compromised when saving it in TIFF format. Additionally, TIFF files can store a large amount of color information and can handle high-resolution images, making it suitable for large format prints that require high-quality and detailed images. Therefore, the statement is true.

Warm colors, such as red, orange, and yellow, have shorter wavelengths and higher energy levels compared to cool colors like blue and green. This difference in wavelength and energy causes warm colors to appear closer to the viewer, while cool colors appear further away. This phenomenon is known as color perspective or atmospheric perspective. It is commonly observed in art and photography, where warm colors are often used to create a sense of proximity or to draw attention to certain elements in the composition.

The color orange is considered a warm color because it is associated with feelings of warmth, energy, and enthusiasm. Warm colors are often associated with fire, heat, and sunlight, and they tend to evoke feelings of comfort and coziness. Orange falls into this category as it resembles the warm hues of a sunset or a glowing fire.

CMYK is the correct answer because it is a color system specifically used for print. CMYK stands for cyan, magenta, yellow, and key (black), which are the primary colors used in the printing process. This color model is used to create a wide range of colors by combining different percentages of these four ink colors. Unlike RGB, which is used for digital displays, CMYK is optimized for printing purposes, ensuring accurate color reproduction on paper.

When you mix blue and yellow together, you get the secondary color green. This is because blue and yellow are primary colors, and when they are combined, they create a new color. Green is a mixture of blue and yellow, and it is considered a secondary color on the color wheel.

The given question asks about the property of color. Out of the options provided, "Light" is the only one that can be considered a property of color. Color is a visual perception that is created by the different wavelengths of light. Therefore, light is an essential property of color.

A primary color is a color that cannot be created by mixing other colors together. It is considered one of the fundamental colors that are used to create all other colors in the color spectrum. Primary colors are typically red, blue, and yellow, and they are used as the basis for color mixing in various art forms and color systems.

A 1 BIT file refers to an image or graphic file that only contains two colors, typically black and white. Unlike other file formats that support multiple colors, a 1 BIT file uses a binary system to represent pixels as either black or white. This format is commonly used for simple images, such as logos or line drawings, where only two colors are needed.

A bitmap is a digital image format that is composed of a grid of pixels. Each pixel represents a specific color or shade, and when combined, they create the visual image. The bitmap itself does not have a physical size until the height and width are specified. This means that the number of pixels in the bitmap is fixed, but the actual physical dimensions can vary depending on how the image is displayed or printed. Therefore, the statement "A bitmap has no physical size until you specify the height and width" is true.

White light is made up of all colors. This is because white light is a combination of different wavelengths of light, which correspond to different colors. When all these colors are combined together, they form white light. This can be observed when white light passes through a prism and gets dispersed into a spectrum of colors, known as a rainbow. Therefore, the correct answer is "All Colours".

JPEG is a lossy compression format developed by the Joint Photographic Experts Group. It allows for extreme compression, making it suitable for reducing file sizes without significant loss of quality. Additionally, JPEG supports various color models, including grayscale, RGB, and CMYK. Therefore, the correct answer is "All of the above."

Printer resolution is measured in DPI, which stands for Dots Per Inch. DPI refers to the number of dots that a printer can produce per inch of paper. A higher DPI means that the printer can produce more dots per inch, resulting in a higher quality and more detailed printout. DPI is commonly used to describe the resolution of both inkjet and laser printers.

A contone image refers to a continuous tone image. Unlike binary images that only have two colors (black and white), contone images have a wide range of colors and tones. They can represent various shades and gradients, allowing for more detailed and realistic representations of images. Therefore, the correct answer is "continuous tone image."

A flat-bed scanner is suitable for scanning reflective artwork because it allows the artwork to be placed flat on the scanning surface. This ensures that the artwork remains in focus and prevents any distortion or blurring that may occur with other types of scanners. Additionally, the flat-bed scanner provides a consistent and even lighting across the artwork, resulting in accurate color reproduction and capturing fine details.

The term HUE refers to the actual color selected. Hue is one of the main properties of color and refers to the specific wavelength of light that is reflected or emitted by an object. It is what differentiates one color from another on the color spectrum. The brightness of color refers to how light or dark a color appears, and the saturation of a color refers to its intensity or purity. However, in this case, the correct answer is the actual color selected.

Halftones are measured in LPI, which stands for Lines Per Inch. LPI refers to the number of lines or dots per inch used to create a halftone image. A higher LPI value results in a finer and more detailed halftone image, while a lower LPI value produces a coarser and less detailed image. LPI is commonly used in printing processes to determine the quality and resolution of the halftone reproduction.

GIGO stands for "Garbage in Garbage Out." This term is commonly used in computer science and refers to the concept that if you input incorrect or low-quality data into a computer system, the output or results will also be incorrect or of low quality. In other words, the quality of the output is directly dependent on the quality of the input. This principle highlights the importance of ensuring accurate and reliable data input to obtain meaningful and accurate results from computer systems.

This statement is false. Bit-mapped files, also known as raster files, are usually larger than vector files. Bit-mapped files store information about each individual pixel in an image, resulting in larger file sizes. On the other hand, vector files use mathematical equations to define shapes and lines, resulting in smaller file sizes as they only need to store the instructions for rendering the image.
