Image Editing Essentials 1 — Questions and Answers
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?
- 2080
- 256
- 1024 (Correct answer)
- 1086
Correct answer: 1024
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?
- PTG.ai (Correct answer)
- PTG.bmp
- PTG.gif
- PTG.jpg
Correct answer: PTG.ai
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?
- Multiplicity
- 3D
- Layers (Correct answer)
- Feathering
Correct answer: Layers
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?
- Copying
- Pasting
- Layering
- Cloning (Correct answer)
Correct answer: Cloning
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?
- Anti-aliasing
- Gradients
- Patterns
- Transparency (Correct answer)
Correct answer: Transparency
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.
Question 6: Which of the following names relates to ready-made raster or vector graphics found online and in various software packages?
- Clip art (Correct answer)
- Photographs
- Art work
- Digital art
Correct answer: Clip art
Clip art refers to pre-made images or illustrations that are available for use in documents, presentations, or digital projects. These ready-to-use graphics, which can be either raster or vector, are typically provided in software packages or found online. They offer a convenient way to add visual elements without creating them from scratch.
Question 7: Jake used a digital camera to photograph the wedding event. The image resolution would be measured in what?
- DPI
- LPI
- PPI (Correct answer)
- SPI
Correct answer: PPI
For digital images displayed on screens or captured by digital cameras, resolution is typically measured in Pixels Per Inch (PPI). PPI indicates the density of pixels within a given inch of the image, directly affecting its clarity and detail when viewed digitally. DPI (Dots Per Inch) is used for print, and LPI (Lines Per Inch) for halftone screens.
