UPBEAR! - 2Principles: Balancesymmetrical - formal
asymmetrical - informal - 3Principles: Proximity / AlignmentGrouping (content, shape, or color)
Lining up (lead eye)
Grids (formalised division) - 4Principles: UnitySimilar Elements
(shapes, colors, typography) - 5Principles: EmphasisParts more important than others
Focal point (seen first)
Contrast - 6Principles: RhythmMovement through repetition
Progressive rhythm
(moves through a design in equal amounts)
Alternating rhythm
(creates a visual flow through a design to direct the viewer) - 7GIMP: Scale Imagepdb.gimp_image_scale
