What is the advantage of using first generation film negative or slide images for scanning?

For every photographic generation, a small portion of the integrity or sharpness and tone quality of the original is lost.

What are masks?

Semitransparent devices that allow the user of an image manipulation program to isolate and protect areas of an image while applying color changes, filters, or other effects to the rest of the image.

Is the principal feature of something in analog format is that it is continuous. An image in analog format has smooth, continuous gradations of tone from light to dark.

analog format

Is the number of bits of color or grayscale information that can be recorded per pixel. The greater the bit depth, the more colors or grayscales can be represented.

bit depth

Is data stored with measured values and distinct points or positions. A digital image is stored with distinct points of varying brightness and color, which are recorded as pixels.

digital format

Is a feature of image manipulation programs used to apply special effects to images, such as textures and patterns.

filter

A(n) _______ is a horizontal display of pixel information in an image capture file.

histogram

Is a graphic display of highlight, midtone, and shadow values that correspond to the number of pixels affected in each part of the tonal scale.

histogram

Layers and filters are two common tools used to edit images in a(n) _______ program.

image manipulation

Is a feature of image editing programs that creates multiple, editable levels of a single piece of artwork.

layers

Is a feature of image editing programs that protects a specified area of an image form changes, filters, and other effects applied to the rest of the image.

mask

Is a feature of image manipulation programs that contains manipulation programs that contains several tools that allow the user to create and color images.

paint effects

Is tools used in image manipulation programs to modify images in ways similar to methods used in darkroom photography.

retouching tools

Is the ability of a digital imaging device to address data in horizontal and vertical dimensions.

spatial resolution

________ resolution refers to the capability of a digital imaging device to address data in two dimensions, horizontal and vertical. _______ resolution is the number of bits of color or grayscale information that can be recorded per pixel.

spatial resolution/tonal resolution

Is the number of bits of color or grayscale information that can be recorded per pixel. The greater the bit depth, the more colors or grayscales can be represented.

tonal resolution

What are the three most common types of USB plugs.

type A, B, and Mini-B

An 8-bit color image is comprised of ____ colors.

256

Describe the difference between an analog image and a digital image.

Analog image is an image in analog format that has smooth, continuous gradations of tone from light to dark and digital image is a digital image stored with distinct points of varying brightness and color, which are recorded as pixels.
