When painting a portrait of a face in proportion, it is important to do all of the following, except

A. to keep the size of the ear the same as the size of the eye.

B. to keep the corners of the mouth lined up with the center of the eyes.

C. to keep the width of the nose the same as the width of the eye.

D. to keep the location of the eyes in the center of the head.

The correct answer is A. to keep the size of the ear the same as the size of the eye.

The correct answer is A - to keep the size of the ear the same as the size of the eye.

When painting a portrait of a face in proportion, it is important to do the following:

B. to keep the corners of the mouth lined up with the center of the eyes.

C. to keep the width of the nose the same as the width of the eye.

D. to keep the location of the eyes in the center of the head.

However, it is not necessary to keep the size of the ear the same as the size of the eye. The size of the ear may vary depending on the individual's facial features and proportions.

To answer this question, we need to identify the option that does not belong to the set of important factors when painting a portrait of a face in proportion. Let's go through each option and determine its validity:

A. To keep the size of the ear the same as the size of the eye: This is an important aspect of proportion when painting a face. The size of the ear should generally be proportionate to the size of the eye to maintain a realistic representation.

B. To keep the corners of the mouth lined up with the center of the eyes: This is another crucial guideline in facial proportion. By aligning the corners of the mouth with the center of the eyes, the artist can maintain balance and achieve a more accurate representation of a face.

C. To keep the width of the nose the same as the width of the eye: This is also an important factor. The width of the nose should ideally be proportionate to the width of the eye to maintain realistic proportions.

D. To keep the location of the eyes in the center of the head: This is a fundamental rule when depicting the features of a face. The eyes should be positioned in the center of the head to maintain the correct proportions and achieve a realistic likeness.

After considering all the options, we can conclude that the answer to the question is A. To keep the size of the ear the same as the size of the eye. This is the odd one out, as it does not reflect an important aspect of facial proportion when painting a portrait.
