  1. To transfer drawings from one surface to another

  2. To create multiple copies of a drawing

  3. To enhance the visibility of details

  4. To correct mistakes in a drawing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A lightbox or tracing table is used in botanical drawing to transfer drawings from one surface to another, allowing for accurate reproduction of the original artwork.

Multiple choice

What is the purpose of a histogram in photography?

  1. To show the distribution of tones in an image

  2. To show the color balance of an image

  3. To show the sharpness of an image

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A histogram in photography shows the distribution of tones in an image, from the darkest to the lightest. It helps photographers to assess the exposure and tonal range of their images.

Multiple choice

What is the role of leading lines in architectural photography?

  1. To draw the viewer's attention to a specific architectural element.

  2. To create a sense of depth and perspective.

  3. To emphasize the symmetry or asymmetry of a building.

  4. All of the above
