Many times, when I design, the end result is such that top part of design is bright and bottom is dark or the opposite. And usually (sometimes not possible) I end up placing copy in 1 part and the product in other part (not deliberately, but it just happens or sometimes it is required). Here's a rough layout for the same:
Does keeping the dark area in the bottom makes any special or significant difference? Or does it signify something special? Some emotion/feeling/characteristic/behavior of a design?
Bonus query: I know that placing product in bottom right corner is often advised. But still I want to know if placing the product at top and copy at bottom OR product at bottom and copy at top (irrespective of above mentioned dark/bright concept) makes some difference?
