Which description explains how a daguerreotype differs from a digital image file?
- A negative used to print matching plates
- A digital file copied without changing data
- One plate image made without a negative
What makes up a raster image, such as a digital photograph?
- Pixels with stored colour values
- Brush marks on a physical canvas
- Light-sensitive silver on a plate
A photo edit can leave no obvious visible mark even though the image data has changed.
Circle one: True False
Which choices can a person make when using an image model?
- Determining every pixel before the model runs
- Only choosing the colour of a finished frame
- Choosing a subject, prompt and outputs
Why can an image model show a gadget that has never been built?
- It photographs an object hidden in a factory
- It generates pictures from learned patterns
- It retrieves a camera record of every object
A generated poster closely imitates a living artist's style. Which response addresses consent?
- Seek permission for the use and respect a refusal
- Add the artist's name and treat that credit as permission
- Label it generated and treat that disclosure as permission
A gallery says a print belongs to an artist-approved edition because its file matches a copy online. What can you conclude from file identity alone?
- Every print must be the same object if the files match
- Identical files prove that no person made the image
- File identity alone does not establish print status
An image claims that a company has built a surprising new gadget. Which approach gives useful evidence before sharing that claim?
- Trust several accounts sharing the same first post
- Trace the source and compare independent evidence
- Treat realistic lighting as proof the product exists

One plate image made without a negative · A daguerreotype forms directly on a plate and has no printing negative. It can still be reproduced by photographing the plate.
Pixels with stored colour values · A raster image stores colour values at positions in a pixel grid. Paint and silver plates are different image materials.
True · Removing an object can look smooth to a viewer. That does not mean the edit is impossible to detect or that the image data stayed unchanged.
Choosing a subject, prompt and outputs · A person can choose the subject, shape the prompt and select outputs. The model also shapes the result, so the person does not directly determine every pixel.
It generates pictures from learned patterns · Generation uses learned patterns to produce an image. It does not require a camera record of the pictured gadget.
Seek permission for the use and respect a refusal · Consent concerns permission for the planned use. Credit and a generated label provide information, but neither establishes the artist's permission.
File identity alone does not establish print status · Identical files establish matching data, not an artist's approval of a physical edition. Prints remain separate objects, and copying does not erase the maker.
Trace the source and compare independent evidence · Tracing the source, comparing independent reports and checking the company's statements can provide evidence. Reposts and realistic appearance do not establish the claim.
