The second most fundamental element of design is shape, because shape is the principal element of identification. The most important thing to keep in mind when shape is the essential element in an image is that it is best defined when the subject is frontlit or backlit. For that shape to be successfully identifiable, it needs to be in strong contrast with its surroundings so that it is detached from the clutter around it.
No design element is more capable of moving your deep emotions than texture. The challenge of seeing and capturing texture is mostly based on one element – light. Texture can be accentuated by the side light of early sunny mornings or early evenings, or by overhead light when the sun is vertical and high in the sky.
Out of the 6 elements of design, line is the strongest and most important and influential. Without line there can be no shape. Without shape there can be no form. Without form there can be no texture and there can be no pattern. Lines are powerful tools that can be used smartly to lead the viewers eyes towards the point of interest in a photograph, and alter the overall feeling and mood of an image.
