The term 'earth shoulders' may refer to a feature in pottery design or a bracing technique in photography. While the term is not standard, it implies a stability or transition zone in the context of the arts.
The phrase 'earth shoulders' is not a common term in any specific academic context. However, the discussion seems to refer to pottery, where the 'shoulder' is part of a pot's anatomy. It is a curve or angle in the pot where changes in its shape or profile may occur, such as where the pot begins to narrow towards the neck or where the handles meet the body of the pot. Likewise,
in photography, the term 'braces' refers to stabilizing the camera to avoid shake, with techniques including leaning on a stable object or using one's body as support. As such, 'earth shoulders' might be interpreted as an angular aspect in pottery or bracing techniques in photography that provide stability or support.
