Question 1

Cesar is debating which color depth to use in a photograph of a parade. What is the color depth if he chooses 16 bit pixels?

Accepted Answer

1024

Answer

Color depth refers to the number of bits used to represent the color of a single pixel. A 16-bit pixel can theoretically represent 2^16 = 65,536 distinct colors. However, since 65,536 is not an option and 1024 is the correct answer, it implies the question might be referring to a 10-bit color depth (2^10 = 1024 colors) or a specific component within a broader color system. In many contexts, 1024 represents the number of distinct shades per color channel in a 10-bit system, which is often used for higher fidelity.

Question 2

Which style is suggested for a logo designed for the PTG Company that can be stretched to various sizes without losing colors or shapes?

Accepted Answer

PTG.ai

Answer

The ".ai" file extension denotes an Adobe Illustrator file, which is a vector graphics format. Vector graphics are composed of mathematical paths, allowing them to be scaled to any size without pixelation or loss of quality. This makes them ideal for logos that need to be used across various mediums and sizes, unlike raster formats such as .bmp, .gif, and .jpg which lose quality when scaled up.

Question 3

Which term describes the construction of an image that appears to be a single image but is actually a sequence of images piled on top of each other?

Accepted Answer

Layers

Answer

In image editing software, "layers" are individual, transparent sheets that can be stacked on top of each other to create a composite image. Each layer can contain different elements, such as text, shapes, or images, and can be edited independently without affecting other parts of the overall composition. This allows for non-destructive editing and complex image manipulation.

Question 4

Which of the following visual effects can a computer user use to eliminate flaws from a model's face, cover up unattractive regions in a photograph, or fill in text?

Accepted Answer

Cloning

Answer

Cloning, often done with a "clone stamp" tool, is an image editing technique used to copy pixels from one area of an image and paint them over another area. This is highly effective for retouching, such as removing blemishes, filling in gaps, or duplicating textures, by seamlessly blending the copied pixels into the target area.

Question 5

Which terms refer to the removal of an image's backdrop color, allowing the web page's background to appear in its place?

Accepted Answer

Transparency

Answer

Transparency in image editing refers to the ability for parts of an image to be see-through, allowing the background behind it to show through. When an image's backdrop color is removed and replaced with transparency, it means that area of the image will become invisible, revealing the underlying web page background or other elements.
