Camera out-of-focus shapes

02 December, 2023


The out of focus circles are formed by the shape of the Aperture and Lens, which is a circle.

All pictures are 1/60s f3.2 but with different focus setting.



To change this, cut out a shape from cardboard and put it in front of the lens.


The out of focus circle now changed to the cardboard shape.
The ISO is increased from ISO400 to ISO640 to compensate for the light reduced by the shape.
