Aspect Ratio: Aspect ratio refers to the proportional relationship between the width and height of an image. It determines the shape and dimensions of the cropped area.
Rule of Thirds: The rule of thirds is a compositional guideline that suggests dividing an image into nine equal parts using two horizontal lines and two vertical lines. The main subject is often placed along these lines or at their intersections for more visually appealing compositions.
Straightening: Straightening involves adjusting the rotation angle of an image so that its horizon or other important elements appear level and aligned properly.
