Bokeh Shapes

Experimenting with custom bokeh shapes

I found a tutorial on youtube which showed how to change the shape of the light bokeh, rather than having the standard circle shape.

 

 

I started with a basic rectangle. I measured the diameter of the lens and created a strip to go around the circumference of the lens.

 

I then attached a flat circular piece and cut a rectangle into this. I made this quite small as was shown in the tutorial. The bokeh shape needed to be smaller than the aperture I used, and this size seemed to work.

This was the bokeh shape taken off the lens.

 

 

 

 

 

 

 

I then took a picture of these lights, to show the rectangular bokeh at different depths of field.

The rectangles aren't entirely clear here, but I took another photo purposely out of focus, which shows the effect. I will try this with different shapes and with different colours of light, and relevant objects in the foreground.

I cut out a square shape and experimented with this in the following photos:

I then (attempted to) cut out a star shape, and used different coloured lights, really emphasising on the depth of field with these photos:

I also tried this square shape on different coloured lights:
