Which aperture setting will bring the maximum area into acceptable focus before and after the primary point of focus?
Karo-lina-s [1.5K]

Answer:

F11

Explanation:

Much of what determines the sharpness in a photo comes from your camera's aperture. If you want everything in the photo be sharp and “in focus”, you will need to select a very closed aperture like F11. As you increase your aperture number, the subjects closer and further away from the subject in focus become sharper.

In an artwork using perspective, at which point do the orthogonal lines in the work merge?
ser-zykov [4K]
The orthogonal lines in the work merge at the vanishing point. In a perspective drawing, the artist uses parallel diagonal lines which meet and diminish to a vanishing point. These lines are called orthogonal and create the perspective and a more realistic view. The vanishing point offers the painting a three-dimensional look.
