3. The resolution is:

Explanation

The correct answer is the degree of sharpness of a computer-generated image as measured by the number of dots per linear inch. This is known as the resolution of an image. A higher resolution means more dots per inch and therefore a sharper image.

Submit
4. A mask is:

Explanation

A mask in image editing refers to a technique used to protect specific areas of an image from being edited or affected. It is similar to using masking tape while painting a house, where certain areas are covered to prevent them from being painted. In image editing, a mask allows for selective editing or adjustments to be applied only to specific parts of an image, while leaving the rest untouched. It acts as a protective layer, allowing for precise control over the editing process.

6. PPI stands for:

Explanation

PPI stands for "pixels per inch." This term is commonly used to measure the resolution of an image or display device. It refers to the number of pixels that can be displayed per inch, indicating the level of detail and clarity in the image. A higher PPI value generally results in a sharper and more detailed image.

Submit
7. JPG stands for:

Explanation

JPG stands for Joint Photographic Experts Group format. The Joint Photographic Experts Group is a committee that developed the JPEG standard for image compression. This format is widely used for storing and transmitting digital images, as it provides a good balance between image quality and file size. It is not related to Java or any specific programming language, and it does not inherently support transparency.

Submit
8. Grayscale is:

Explanation

Grayscale refers to the color "space" or document type that includes black, white, and all shades of gray. It does not include any other colors. In this color space, the intensity of each pixel is represented by a single value, ranging from 0 (black) to 255 (white). This allows for the representation of images in black and white, as well as various shades of gray, without any other colors present. Grayscale is commonly used in printing, photography, and digital imaging.

Submit
9. RGB stands for:

Explanation

RGB stands for "Red, Green, Blue" and is a color producing mode using "additive primaries". In this mode, the light of the monitor display is added together in varying intensities to create a wide range of colors. By combining different amounts of red, green, and blue light, any color can be produced on the screen. This is the standard color model used in electronic displays such as computer monitors, televisions, and mobile devices.

Submit
10. Line art is:

Explanation

Line art refers to an image that is composed solely of solid areas, without any shading or gradients. It typically consists of black lines on a white background, although it can also be created using other colors. Unlike other types of images, line art does not use varying tones or shades to depict depth or texture. Instead, it focuses on the use of clear and distinct lines to convey the intended image or design.

Submit
11. The GIF file format uses an indexed color compression based on a 512 color palette.

Explanation

The GIF file format uses an indexed color compression based on a 256 color palette, not 512.

Submit
12. DPI stands for:

Explanation

DPI stands for "dots per inch." It is a measurement used to determine the resolution or clarity of an image or printed document. The higher the DPI, the more dots or pixels are present per inch, resulting in a higher quality and more detailed image. DPI is commonly used in printing and digital imaging to ensure that the output matches the desired level of detail and sharpness.

Submit
13. LPI stands for:

Explanation

LPI stands for "lines per inch." This term is commonly used in printing and refers to the number of lines or dots that can be printed within an inch. It is a measure of the resolution or image quality that can be achieved in a printed document. The higher the LPI, the finer and more detailed the print will be.

Submit
14. To "feather" is to:

Explanation

Feathering refers to the process of adjusting the edges of an image to make them appear softer and more blended with the background. This is achieved by gradually reducing the opacity of the pixels along the edge, creating a smoother transition between the image and its surroundings. By making the edges more transparent, the image seamlessly integrates into the background, resulting in a more natural and professional look.

Submit
15. A pixel is:

Explanation

A pixel is the smallest element of an image that can be individually processed in a video display system. It refers to a single point in a digital image, and each pixel contains information about its color and brightness. In a video display system, pixels are arranged in a grid pattern to form the complete image. Each pixel can be individually controlled and manipulated, allowing for precise editing and processing of digital images.

Submit
16. Anti-aliasing is:

Explanation

Anti-aliasing is a technique used to blend bitmap-based images and text in order to reduce the stair-stepping or jagged appearance. It smooths out the edges of the images or text by adding shades of color to the pixels along the edges, creating a more visually pleasing and smoother appearance. This technique is commonly used in digital graphics and typography to improve the overall quality and clarity of the displayed content.

Submit
17. A halftone image is:

Explanation

A halftone image is the result of converting an image into a set of different-sized dots that fool the eye into believing that it sees a continuous tone. This technique is commonly used in printing to reproduce continuous tone images using only black ink or a limited number of ink colors. By varying the size and spacing of the dots, the illusion of different shades and tones is created. This allows for the reproduction of photographs and other complex images using a limited color palette.

Submit
18. A Raw file format is all of the below except:

Explanation

The given answer states that a raw file format is not the native format for Photoshop. This means that Photoshop does not directly support raw files and requires them to be converted into a compatible format before they can be edited in the software. Raw files are typically unprocessed and contain all the data captured by the camera's sensor, making them similar to a photo negative. However, they are not exclusive to Photoshop and can be used with other image editing software as well.

Submit
19. Vector graphics are:

Explanation

Vector graphics are composed of mathematical descriptions of lines and shapes, allowing them to be scaled and resized without losing quality. Unlike bitmap images, which are made up of individual pixels, vector graphics are based on mathematical equations and can be edited and manipulated easily. This makes them ideal for creating logos, illustrations, and other types of artwork that require precise and scalable graphics.

Submit
20. The page guides are:

Explanation

The correct answer is the invisible lines that can be dragged from the edge of the rulers (horizontal or vertical) to use for alignment or margins. This answer accurately describes the function of page guides, which are used to create precise alignments and margins in a design or layout. These guides are typically represented as non-printing lines that can be dragged from the rulers to establish the desired positioning of elements on a page.

Submit
21. Ths PSD file format is all of the below except:

Explanation

The given answer states that the PSD file format is not a format that supports Photoshop layers. This means that the PSD file format does indeed support Photoshop layers.

Submit
22. A bitmap is:

Explanation

A bitmap is a color "space" or document type that is defined by using either on (white) or off (black) pixels. In other words, it represents an image using a grid of pixels, where each pixel can be either black or white. This allows for the creation of digital images that are composed of solid areas of color, without any gradients or shades.

Submit
23. Color mode is:

Explanation

Color mode refers to the color "space" or document type that determines how colors are structured in a file. It defines the range of colors that can be used and how they are represented. Different color modes, such as RGB or CMYK, have different structures and are used for different purposes. For example, RGB is commonly used for digital displays, while CMYK is used for printing. The color mode affects how colors are combined and displayed in an image, and it is an important consideration when working with digital files.

Submit
24. A raster image is:

Explanation

A raster image is a grid of individual bits in rows and columns called a bitmap. This means that the image is made up of a series of pixels, each represented by a bit, arranged in a grid-like structure. Raster images are commonly used for representing photographs and complex graphics, as they can accurately capture the details and colors of the original image. They are different from vector images, which are composed of mathematical descriptions of lines and shapes. Raster images are also often associated with specific color spaces or document types, including black and white and various shades of gray.

Submit
25. TWAIN is the interface standard for Windows only, that allows imaging hardware devices (such as scanners and digital cameras) to communicate with image processing software.

Explanation

The given statement is false. TWAIN is not limited to Windows only. It is a widely used interface standard that allows imaging hardware devices to communicate with image processing software on multiple operating systems, including Windows, Mac, and Linux.

Submit
26. To rasterize is to:

Explanation

Rasterizing refers to the process of converting a vector image, which is composed of mathematical equations and lines, into a bitmap image, which is made up of individual pixels. This conversion allows the image to be displayed or printed at a specific resolution, as each pixel represents a specific color value. Rasterizing is commonly used when preparing images for digital or print media, as it ensures that the image appears as intended and can be accurately reproduced.

Submit
27. CMYK stands for:

Explanation

CMYK stands for the color "space" or document type which is based on the absorption and reflection of light. This color model is used in printing and refers to the four ink colors used: cyan, magenta, yellow, and key (black). By combining different percentages of these colors, a wide range of colors can be achieved. Unlike RGB, which is an additive color model used for electronic displays, CMYK is a subtractive color model where the colors are subtracted from white light to create the desired color. This is why CMYK is commonly used in printing, as it accurately represents the absorption and reflection of light on paper.

Submit
28. The TIFF file format (Tagged Image File) was created in the 1980's to work acroos several platforms. It provides a way to use small, compressed files.

Explanation

The given statement is false. The TIFF file format was actually created in the 1980's to provide a way to store and exchange high-quality images. It is a flexible format that supports various types of data, including uncompressed and losslessly compressed images. While TIFF files can be compressed, they are generally larger in size compared to other image file formats. Therefore, the statement that TIFF files provide a way to use small, compressed files is incorrect.

Submit
29. Resampling is:

Explanation

Resampling is the command used to increase or decrease the size and/or resolution of a bitmap-based image. This process involves changing the number of pixels in the image, either by adding or removing them, which in turn affects the overall size and clarity of the image. Resampling is commonly used in graphic design and image editing software to adjust the dimensions and resolution of an image to fit specific requirements or to enhance its quality.

Submit
30. Select all the boxes  that apply to a bezier curve.

Explanation

A bezier curve is a curved line or path that is defined by mathematical equations. It is named after Pierre Bezier, a French mathematician and engineer who developed the concept. Most graphics software includes a pen tool specifically designed for drawing paths with bezier curves. The most basic bezier curve consists of two end points and control handles that are attached to each node, allowing for precise control over the shape and direction of the curve.
