    Which bicubic resampling method is best if enlarging an image from 300 pixels wide to 800 pixels wide?

    Explanation
    Bicubic resampling method is the best for enlarging an image from 300 pixels wide to 800 pixels wide. Bicubic interpolation uses a weighted average of 16 neighboring pixels to calculate the color value of a new pixel. This method produces smoother and more accurate results compared to other resampling methods, making it ideal for enlarging images while preserving details and minimizing artifacts.

    If the resolution of an image is 72 dpi and the image is 8 inches wide by 10 inches tall, how many pixels wide is the image?

    Explanation
    The resolution of an image refers to the number of dots per inch (dpi) that the image contains. In this case, the image has a resolution of 72 dpi. The width of the image is given as 8 inches, so to find the number of pixels wide, we can multiply the width by the resolution: 8 inches * 72 dpi = 576 pixels. Therefore, the image is 576 pixels wide.

    Which font design is generally thought to instill trust in the reader?

    Explanation
    Sans serif fonts are generally thought to instill trust in the reader. This is because sans serif fonts have a clean and modern appearance, which can convey a sense of professionalism and reliability. The absence of decorative strokes on the characters also makes the text easier to read, enhancing comprehension and trustworthiness. Additionally, sans serif fonts are commonly used in formal and business settings, further associating them with trust and credibility.

    Types of images composed of lines, curves and fills are called vectors?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Images composed of lines, curves, and fills are called vector images. Vector images are created using mathematical equations and can be scaled to any size without losing quality. They are resolution-independent and can be easily edited and manipulated. Unlike raster images, which are made up of pixels and can become pixelated when resized, vector images maintain their sharpness and clarity. Therefore, the statement "Types of images composed of lines, curves, and fills are called vectors" is true.

    Which color model is used for commercial printing of a magazine?

    • RGB

    • CYMK

    • JPEG

    • BItmaps

    Correct Answer
    A. CYMK
    Explanation
    The CYMK color model is used for commercial printing of a magazine because it stands for Cyan, Yellow, Magenta, and Key (black), which are the primary colors used in the printing process. This color model is specifically designed for printing purposes and ensures accurate color reproduction on paper. RGB, JPEG, and Bitmaps are not suitable for commercial printing as they are primarily used for digital displays and do not provide the same level of color accuracy and detail required for print.

    What RGB color bit depth is needed to create 256 colors?

    • 16 bit

    • 12 bit

    • 8 bit

    • 80 bit

    Correct Answer
    A. 8 bit
    Explanation
    The RGB color model uses a combination of red, green, and blue channels to create different colors. In this question, the requirement is to create 256 colors. To achieve this, we need a bit depth that can represent 256 different values. The bit depth determines the number of possible values for each channel. In this case, an 8-bit color depth provides 256 (2^8) different values for each channel, allowing us to create a total of 256 colors. Therefore, the correct answer is 8 bit.

    Which color model is used by computer monitors?

    • RGB

    • CMYK

    • Bitmap

    • All of the above

    Correct Answer
    A. RGB
    Explanation
    Computer monitors use the RGB color model. RGB stands for Red, Green, and Blue, which are the primary colors of light. In this model, different intensities of these three colors are combined to create a wide range of colors on the screen. Each pixel on the monitor is made up of tiny red, green, and blue subpixels, and their varying intensities determine the color displayed. This color model is widely used in digital displays, including computer monitors, televisions, and mobile devices. CMYK is primarily used in printing, and bitmap refers to a specific file format, so they are not the correct color models for computer monitors.

    Explain what happens when a image contains a color that is undefined in a web browser.The Image is ____________, and the software creates a color through _________. 

    Correct Answer
    dithering
    interpolation
    Explanation
    When an image contains a color that is undefined in a web browser, the software uses dithering to create a color that closely approximates the undefined color. Dithering is a technique that adds noise or patterns to the image in order to create the illusion of a color that is not actually present. This helps to maintain the overall visual quality of the image. Interpolation, on the other hand, is a technique used to estimate values between known data points. In the context of this question, interpolation is not directly related to the creation of a color for an undefined color in an image.

    What are the two aspects of optimizing a raster image for use on a website or handheld device?

    • Applying the correct crop to the image.

    • Applying a resolution of 72 and png.

    • Apply a resolution like the other ones on the internet.

    • Applying the most appropriate resolution and file compression.

    Correct Answer
    A. Applying the most appropriate resolution and file compression.
    Explanation
    The two aspects of optimizing a raster image for use on a website or handheld device are applying the most appropriate resolution and file compression. By choosing the right resolution, the image can be displayed clearly without taking up excessive space. File compression reduces the file size without significantly affecting the image quality, allowing for faster loading times and better user experience.

    How can an uncompressed RAW image file type be obtained?

    • Download it from a website with good images.

    • Download it from a cellphone.

    • Download it from a digital SLR camera.

    • Download it from a digital phone camera.

    Correct Answer
    A. Download it from a digital SLR camera.
    Explanation
    An uncompressed RAW image file type can be obtained by downloading it from a digital SLR camera. Digital SLR cameras are capable of capturing images in RAW format, which preserves all the original data captured by the camera's sensor without any compression or processing. This allows for greater flexibility in post-processing, as RAW files retain more detail and provide more latitude for adjustments compared to compressed image formats.

    The process of converting a vector image into a raster image is called bitmap tracing.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Bitmap tracing is the process of converting a vector image, which is composed of mathematical equations and lines, into a raster image, which is made up of individual pixels. This involves tracing the outlines of the vector image and converting them into a grid of pixels. Therefore, the statement that the process of converting a vector image into a raster image is called bitmap tracing is true.
