Perception of Light and Shadow

Perception of Light and Shadow

This skill is very important because it allows an artist to make objects and space look three-dimensional with the use of “shading.” Value is understood as darkness and brightness, and it is key to observe the differences in tones of light and dark within whatever space you are drawing. Pale, light tones are said to be “high” in value and dark tones are “low” in value.

Value, Light, and Shadow



The conversion from color to a different shade of gray is called value, therefore, every
color has value. Both shadow and value are sued by designers to act as the basis for making any rendering look realistic. Without these values, a drawing has no depth or basic three-dimensional form. The objects would appear flat and uninteresting.

A highlight is known as the brightest light and appears where light form the source falls most directly on the object. A cast shadow is when an object blocks light rays and creates the darkest shadow. On the other hand, a crest shadow is any shadow on the crest of a rounded form, typically between the highlight and reflected light. These are very difficult to distinguish, but it is the key to round out the object in a three-dimensional form. Reflect light, as briefly mentioned, is when light is reflected back onto the object from the surface around the object. The surfaces of an object that do not receive direct light rays are in shade. Typically, a reflected light is on a shaded surface.

Creating Contrast on an Object

Contrast on an object is very important in showing the sense of depth and three-dimensional form. Contrast means to show different values on two surfaces using values not close on the value bar. A strong contrast means that two values are further apart on the value bar, whereas soft contrast means that two values are closer together on the value bar. If there is not contrast of value in a drawing, then the space and/or object looks flat and lacks a sense of three-dimensional form and depth.

    Again, I appreciate how you set up your blog, it is both aesthetic and easy to read. Also, I liked how you put a picture to help with understanding of shadows and then also proceeded to describe the picture

Proportion and Details

Image
  Proportion and Details When it comes to hand rendering, we have learned – a great deal – that marker, pencils, and often Sharpies, make up the best medias. Within these medias, however, there are certain ways to effectively communicate texture, volume, color and light, and the overall color scheme within a render. How one goes about achieving these details is shown through their technique. Texture and Volume The texture plays a large role in rendering because it shows the realism of an object or  environment. When using appropriate techniques such as differing line qualities, the contrast within a space is more readily defined and obvious. When it comes to volume, the size and position of an object is equally relative, in addition to the proportion. By displaying different values, the sense of volume greatly increases. Line qualities can equally affect an objects texture or value based on the lighting within the space. This can also create a sense of distance and volum...

Texture

  Texture When it comes to hand rendering, especially interior spaces, it is critical to display the correct texture of a surface or object. Without this, all surface and objects can easily be portrayed as solid and smooth when, however, that is not always the case. Learning how to resemble different textures with different mediums and techniques is as equally vital for an interior designer. Texture with Pencil When drawing with pencil it is best to keep your hand light and hold your pencil a bit further from the tip than usual. Pencil allows an artist to build value and complexity within a drawing over time. The more times you go over something, obviously, the darker it will become – with pencils. Take windows, for instance, and how adding details creates interest within these features. Due to the fact that pencil is the chosen medium, it is good to understand that there is considerable variation in the tonal values, especially within the windowpanes. Also note that the sunl...
