ASS. 1 | IMAGES + CHAPTERS + MANIPULATIONS

The chapters are divided and now the manipulating starts. To give you a brief impression of the kind of manipulations we made, an example of a manipulation for every image is posted here.

POP OUT!

*Red Blur

The red figure overhangs from the background because its color and shape:

Color: The red color has a strong contrast with the blue-white environment.

Shape: The general shapes in the poster are built with straight lines while the red form has many edges that can be distinguished at first sight.

*Yellow triangle

This shape pops out but in a less important way because it is smaller than the red form.

Color: The yellow color has a huge contrast with the blue-white surrounding.

Orientation: the text in the poster is aligned vertically in a virtual straight line while this triangle seems to be rotated for the vertical axis.

The upper label is clearly separated from the background. This is part­ly done through colour. The colours are different from the background so they don’t belong to the back­ground. But done through contour/ square shape, for even though multiple colours are used, you still feel they all belong to the label. The lower label emphasises this last remark, for here a part of the label is almost equal to the colour of the background. Yet still you recognize this part to belong to the label. The labels appear more likely to belong to the same group because they are both oriented in the same horizontal direction.

Bottom-up (information drives pattern building, features à patterns à objects): In the first stage, when looking at the image an enormous amount of features arrives at the eye. In the second stage brain pixel processors detect the different feature information and divide the visual field up into areas of common colour and texture, which results in continuous contours; patterns, e.g. many dark blue features next to each other in three separate groups. In the last stage the patterns are processed into a small number of visual objects. In the example the dark blue patterns are three wineglasses. When the dark blue features would be all different (A), a wineglass would not be visible. Dark blue features at the outside of the object, like a stroke (pattern) (B) is already more supporting in perceiving an object than when all features would be different.

Linear perspective as shown by the red lines. They merge into a vanishing point. The two vanishing points combined form a base for the horizon assuming they are parallel. The horizon indicates the viewpoint from the painter. Which tells us he must have been on the same height of the second floor windows on the right side of the painting.
