Fo­cal length

This refers to the dis­tance be­tween the lens and the sen­sor when the sub­ject is in fo­cus. Geo­met­ric and chro­matic dis­tor­tion may vary de­pend­ing on the fo­cal length used.

Moiré pat­terns

Tex­tures with densely packed de­tail can cause strob­ing, wave-like pat­terns and un­wanted colour band­ing. Ar­chi­tec­ture and cloth­ing are both par­tic­u­larly sus­cep­ti­ble to moiré pat­terns.
