ABOUT BOOKMARK's SKETCHBOOK

Bookmark's sketchbook contains on line lessons and course review material for students studying art and drawing. The sketchbook is exactly what the name suggests, a book of sketches. The sketches are used as a reference library of art ideas for lessons given in graphic design and game development. The majority of sketches are produced with pen on paper. There are a number of illustrations that were drawn with Microsoft Word drawing tools. Besides a reference book, these sketches are used in Photoshop lessons that teach graphic editing, color design and composition. The graphics are also used in Flash animation and game development lessons.

In today's lesson statues were constructed in the foregrounof a 3D roman city. The initial sketch was drawn with a 0.5 micron pen on 70 pound paper. The lines were drawn very lightly. The sketch was then scenned into the photoshop (without removing it from the sketch book). The cover could only be partially closed because of the width of the sketch book. Photoshop had to be used to change the constrast, brightness and exposure of the picture so that the the lines could be seen.

This is the scan without any editing, as is with the cover of the copierleft open for the scan. The open cover resulted in a scan without dark spots on the left hand edge.

Although the image can be seen it is definitely too bright and the lines difficult to see. Photoshop can be used to improve the quality of the image significantly.

Today a 0.7 micron pen was used to darken yesterdays 3D roman statue city. This scan is as is with no Photoshop adjustments for brightness or contrast.

Examining sketches for contrast is one way for students to determine how natural they are at applying contrast to composition. For most drawings, there is a higher level of contrast (the difference between the values of the black and white values of objects) in the foreground than there are in background objects. That issue puts the clothes clip sketch in question.

The clothes on the lower left of the sketch imply a dark color which not only goes against the natural light to dark perspective gradient of light that the eye is used to seeing, but also off centers the composition. Improvements in the arrangement of this clip art sheet would require either removing a considerable amount of black from the lower cloth or moving it behind the legging that is now in front of it.

If you examine most photographs the background is difficult to distinguish not only because the objects are smaller, but also because light tends to diffuse in the distance. This diffusion results in darks appearing lighter and lights being darker in the background.

Although this rule can be generally applied when the lighting is uniform, the rule changes when lighting condition changes. When one examines night photos, their is little light to diffuse and the unlit background can appear darker than the shadows in the lit foreground. In this situation any light in the background tends to diffuse into the darkness.

When shadows from objects (such as a row of trees that recede into the distance) the contrast between the shadows and the adjacent lit areas is less for the shadows closer to the viewer than shadows farther away.

Illusions can be created with shadows. A constant uniform shade of gray will appear as gradient of gray if it is placed over a graded gray background. When observing shading in real life one has to be aware of this illusion. Although the shadow appears to be getting lighter in the background, the underlying surface of the background is becoming darker (the light rays reflected from the background are being scattered).

For adequate representation of depth in shading, the designer has to decide on what will be the level of contrast between the objects that are closest to the viewer and the objects that are farthest from the viewer. A shading gradient can even be derived from which to estimate the relative change in

In this lesson, perspective concepts are used to sketch city scenes. Students are required to use cylinders in the design (often in the form of columns). . The Alberti grid also must be included in the design After the sketch is created, students are edit the graphic for includsion on a web site. Because color is more effective in web presentations, students often chage the color balance, hue and then use the curves feature of Photoshop to alter the color. The illustration produced in Photoshop is used to emphasize and point out areas that need need edge and tonal corrections.

The Sketch of the day. Shoes

Drawing shoes can be a challenge. They are geometrically involved, something that you can't forget especially when you are drawing shoes in action. All of these shoe designs were pieced together with the fundamental shoe building blocks. These include the heel, the tongue, ankle supports and ball supports.

Today's reading material, which is about shoes, discusses the various aspects of shoe design. Several images are included that feature current fashion in shoes in Europe, the Uniteds and Brazil.
