Form/Modeling

Form is…•Is a term that is used to describe the visual appearance and shape of something.  In a drawing form can be represented with lines and as a series of tones ( a range of values from light to dark) known as modeling.

Modelling…•Indicates the solidity and three-dimensional quality of a form, which is often enhanced or accentuated by light hitting the form and creating shadows.

•There are several different techniques to use for modeling, depending on which type of media you choose.

SHADING TECHNIQUES Look  at the drawing of the Astronauts. Here the artist creates a work so real it looks almost like a photograph. Do you know how this is done? One technique he uses to get this result is shading. Shading is the use of light and shadow give a feeling of depth.  There are four basic shading techniques  Hatching is drawing a series of thin lines running parallel, or in the same directiom .  Crosshatching is drawing lines that crisscross each other.  Blending is smoothly drawing dark values little by little by pressing harder on the drawing medium.  Stippling is creating dark values with a dot pattern.

 Hatching

Hatched lines can be drawn close together to give a dense tone or quite freely, depending on texture and nature of image

•Hatching characteristics are that the lines are never blended together and remain vibrant.  

•Is a form of hatching combining 2 or more sets of parallel lines that cross one another at an angle.  They can be used to create a sense of form. (cross-hatching)

other techniques:

Bracelet shading is a series of curved parallel lines that give the impression of a tubular form the rounded effect that it produces on these trees gives an illusion of reality it does not need to be uniform and rigid – you can use it to go over swells, etc. Best with pen and ink or technical pens for this type of shading.

•Feathering attempts to blend tones optically so that while the individual marks are retained they can be overlaid to create a shimmering effect and lightness to what is seen.

Stippling

•Note there are many different ways of modeling depending on what type of media you choose.  Each medium gives a characteristic set of marks you express.  

•LOW KEY VALUE: Predominately dark values often used to create an effect of gloom, mystery, drama, menace, or. Heaviness

•HIGH KEY VALUE: Predominately light values often used to create an effect opposite of low key value, such as light-heartedness, delicateness, or whimsy

•Good to do a key when you are drawing and adding shading: deconstruct into at least 4 tones: light to dark

•VARIATIONS WITHIN LARGER SHAPES OF VALUE. Once the largest, simplest areas of shadow have been identified and blocked in, begin to note the subtle variations found within that larger, simpler shape. A large shape of middle tone value, for example, will often contain smaller passages of somewhat lighter and darker values

•THE SHAPE OF AREAS OF SHADOW AND LIGHT

•. -            What is the shape of the shadow in its largest, simplest form, and how does that shape relate to the form in its entirety? Where is the shape located? How large or small is it in relation to the surrounding area? How does it relate to other shapes of value on the form in terms of size and position and darkness or lightness

•Single Hatch

•Cross Hatch

•Shade with value!!

•Secrets:

• to go light and follow the contour of the object you are drawing.

• Cross-contour – to imply the form.

•Watch your edges!!!
