What are the two most important elements that create the illusion of depth on a flat surface?

Perspective and color

Explanation:

The two techniques that help in creating an illusion of depth on a flat surface are perspective and color.

Perspective can be defined as an art of creating three-dimensional objects on a two-dimensional surface. This technique in drawing helps to create a realistic painting on a piece of paper or canvas (two-dimensional). It helps in creating an illusion of space and depth in a painting or drawing.

Color is the other technique used to create an illusion of depth on a flat surface. Depth can be created depending upon the color of the background. Cool colors such as blue, green, etc will appear farther and warm colors such as red, yellow, orange, closer on a black background. On the other hand, on white background, cool colors appear near and warm colors farther.

So, the correct answer is perspective and color.

sorry. my computer broke down and i had about 3 doctor's appointments. i'm just catching up now after reinstalling a router.

i think you best answer to this is d. some film directors were very picky about roles and lighting and and which side of the face the camera should catch. they were also picky about sound and background noise and chatter and music and all sorts of what we would consider trivial things. a stage director has to have all this ironed out before the curtain goes up. if he doesn't he better do it soon. if he doesn't notice, critics soon will, and they are not a very nice bunch.

e: both have the power to ask for rewrites. theater directors are always yammering about act 2.

c is true. both can ask for any number of things during rehearsals. the reason i wouldn't pick c is because a film director can make changes anytime during shooting, including when he thinks they ought to be done shooting.

b i didn't know what blocking was and i can't find a good description. if you have one and think b is true, go for it.

a a film director quite frequency chooses the leading lady or man. he may not have the final word, but he chooses. sometimes a theater director has no choice. a is generally not true.
