Concept: Horizontal is the basic of all being. All floor or ground has to level to horizontal. All pillars and buildings stand upon horizontal. The day begins with sunrise at the horizon... Horizontal lines are everywhere, but hard to come across in its pure form. They may be boring to some, but they can also be beautiful and colourful. Let's discover the creative horizon together... "rules": 1] all images must be tagged "horizontal". 2] all images must be in landscape format, 4:3 aspect ratio 3] all images must have objects in horizontal direction 4] horizontal lines that formed by objects should be at or closed to 180 degrees. 5] horizontal lines should extend from the left edge to the right edge of the images 6] all horizontal element must be created by objects, by negative space within an object, by light and shadow, or by a groove or ridge that creates lines on a surface. 7] no CG (computer generated) please.
