Question about the concepts for grid
 
Hi,

May I ask what's the difference between orthogonality and aspect radio?

Thank you very much. Could you also give the definition of them?

Orthogonality occurs when two planes are perpendicular to each other.
Aspect ratio is ratio of the length to width of your image.
