Grade Details - All Questions

Question 1. Question : Contrast between light and dark establishes edges or boundaries between forms, how dark or light an object is compared to the object or space next to it. Student Answer:  True  (Colors can be translated to dark or light value, absorbing and reflecting different amounts of light. Dark colors will absorb more light so value changes won’t be as apparent as on light or white objects, which will reflect more light.)  False Points Received: 3 of 3 Comments: Question 2. Question : Which of these is the softest grade of graphite pencil? Student Answer:  4B (Reflected light is the light bouncing off of another surface onto the shadowed side of an object. This usually appears as a thin line of faint or subtle light near the base of an object just above the cast shadow.)  2H  2B  B Points Received: 3 of 3 Comments: Question 3. Question : When a single light source is present, shadows will fall to the same sides of objects in a set-up. Student Answer:  True  (When there is one light source on a set-up, the cast shadows will be on the same sides of the objects opposite the light source and the highlights. This is important for consistency and realism in shading.)  False Points Received: 3 of 3 Comments: Question 4. Question : Compressed charcoal and vine charcoal will give the same types of dark values. Student Answer:  True  False  (Vine charcoal is the softest and most versatile form of charcoal. It is easy to apply, blend, and erase; however, it can be difficult to achieve dark, even, black tones and it does not adhere to the paper as well as compressed charcoal. Compressed charcoal is sold in sticks and blocks. It is very dark and does not erase easily.) Points Received: 3 of 3 Comments: Question 5. Question : To begin developing shading in a drawing once the basic shapes, composition, and proportions are established, block in the darkest values across the scene first. Student Answer:  True  (To begin developing a drawing, start with a gesture sketch, then block in your objects as geometric shapes using sighting, take a moment to step back and assess the perspective and proportions, and then systematically establish the darkest shadow areas first to describe a consistent light source. Everything opposite the light should be a darker value, everything closest to the light is a highlight, and everything in between these two extremes is a transitional tone.)  False Points Received: 3 of 3 Comments: Question 6. Question : Edges or boundaries of objects and spaces are defined by the contrast of values, light against dark, rather than outlines. Student Answer:  True  (Contrast between light and dark establishes edges or boundaries between forms, how dark or light an object is compared to the object or space next to it. Location in course lectures: Logical Flow of Light & Shadow, interactive tutorial with eggs.)  False Points Received: 3 of 3 Comments: Question 7. Question : What is reflected light? Student Answer:  The lightest part of an object  The effect of light on an object caused by light bouncing off a surface plane (Reflected light is the light bouncing off of another surface onto the shadowed side of an object. This usually appears as a thin line of faint or subtle light near the base of an object just above the cast shadow.)  Light values around an object  Light passing through a transparent surface Points Received: 3 of 3 Comments: Question 8. Question : Which condition is important to consider for realistic shading in a drawing? Student Answer:  Light direction  Surface texture and color  The directions, proportions and relative values of shadows  All of the above (Study the direction of the light source on the scene, and how this determines the directions, sizes and relative values of shadows and cast shadows. The surface texture and color of an object will also affect the amount of contrast. Colors will absorb light while light or white surfaces will have more intense highlights.) Points Received: 3 of 3 Comments: Question 9. Question : The values between the lightest and darkest values in a scene are called what? Student Answer:  Middle values  Highlights  Shadows  Transitional tones (Transitional tones refer to the way a value becomes darker or lighter across a form or space. These are most apparent on rounded forms, where the change from dark to light is often smooth and more gradual than on angular geometric forms, where the change can be more distinct between surface planes.) Points Received: 3 of 3 Comments: Question 10. Question : An effective way to see values and value relationships in a scene is to squint at the subject. Student Answer:  True  (Squinting helps to see the essential shapes and positions of the main areas of light and dark in a set-up or scene.)  False Points Received: 3 of 3 Comments:
