A small raster photo is enlarged for a poster. Which result should you expect?

A
It captures new detail because the image has more pixels.
B
It estimates additional pixels without creating newly captured detail.
C
It increases the original sensor's bit depth.
D
It changes the image's color model to RGB.

You have an image with a fixed pixel count and want to print it larger. Which statement best describes the role of PPI?

A
It describes how many color channels each pixel stores.
B
It determines how many pixels are added to the image.
C
It describes pixel density for the printed size.
D
It specifies the physical print size without reference to pixels.

You are exporting a graphic with crisp edges and a transparent background. Which format is the best fit among these choices?

A
JPEG, because it is designed to retain transparency with lossless compression.
B
PNG, because it retains pixel data and supports transparency.
C
TIFF, because it always uses lossy compression.
D
JPEG, because it preserves every pixel exactly.

An editor wants smoother tonal changes and more flexibility when adjusting color. Which image property is most directly relevant?

A
It describes how many possible values each color channel can store.
B
It describes the physical width and height of a print.
C
It determines how many pixels are in the image grid.
D
It specifies how many times an image has been compressed.

Which workflow best protects an image while allowing edits to be revised later?

A
Overwrite the only copy and flatten all changes immediately.
B
Repeatedly save the same lossy-compressed file to preserve editability.
C
Keep an untouched original and make revisable changes in a working copy.
D
Increase PPI before editing so the original pixels cannot change.

Before exporting an image for a particular screen or print size, which dimension check is most useful for judging whether its stored detail is suitable?

A
Check only the PPI value; it guarantees enough image detail for any output size.
B
Check whether the pixel width and height suit the intended screen or print size.
C
Check only the file name; it determines the displayed dimensions.
D
Check whether the file uses RGB; that guarantees a suitable pixel count.

You need a version for continued editing and another version optimized for a website. Which workflow best meets both needs?

A
Retain a master file and export a separate delivery copy suited to the destination.
B
Replace the master with a smaller JPEG so every future use has the same settings.
C
Discard the editable version once a delivery copy has been exported.
D
Use the same compressed delivery file as both the master and every future export.

Before exporting a print image, you must meet a specified print-size requirement, use a particular color workflow, and retain creator metadata. Which export checks directly address those requirements? Select all that apply.

A
Check that the pixel dimensions suit the required print size.
B
Check that the color mode and embedded color profile suit the workflow.
C
Check whether descriptive metadata, such as the creator, should be retained.
D
Check only whether the image looks correct on screen; the other requirements need no checks.
E
Choose the strongest compression available, regardless of the required format.
