Photoshop Quiz Digital Image

1. What is a pixel?

A small, woodland creature when captured grants you one wish

A picture element that is one tiny square

An 8 bit depth image

A million megapixels

A pixel is a picture element that is represented as a tiny square in digital images. It is the smallest unit of a digital image and contains information about color and brightness. Multiple pixels together form an image by combining different colors and shades.

2. What is a digital image?

A two dimensional mapping of pixels that are themselves made out of bits.

A three dimensional mapping of depth color and resolution over a grid of dpi

A tiny square of color and light

A JPEG

A digital image is a representation of visual information in a digital form. It consists of a two-dimensional grid of pixels, which are the smallest units of the image. Each pixel is made up of bits, which determine its color or intensity. Therefore, a digital image can be described as a two-dimensional mapping of pixels that are themselves made out of bits.

3. How many megapixels would I need to produce an awesome 8x12 print?

12.7

10.5

12.4

18.6

To produce an awesome 8x12 print, you would need a camera with at least 12.4 megapixels. This is because the resolution of the image needs to be high enough to capture the fine details and ensure a sharp and clear print at that size. A higher megapixel count allows for more information to be captured, resulting in better image quality and detail.

4. Which answer best describes the file format Portable Network Graphics (PNG)?

Very large, not transparent, 8 bit color depth

Very large, not transparent, 24 bit color depth

Small file size, usually associated with a scanned image

Small file, transparent, 24 and 8 bit color depth

The correct answer describes the file format PNG as a small file that is transparent and supports both 24 and 8 bit color depth. PNG files are commonly used for images that require transparency, such as logos or graphics with a transparent background. The file size of PNG images is generally smaller compared to other formats like JPEG, while still maintaining good image quality. Additionally, PNG supports both 24-bit true color and 8-bit indexed color, providing flexibility in terms of color depth.
