FINALLY!!! I figured out this trick . I have tried before but it didn’t work. Today looked for more info and apparently the figure I previously cut was too small. I cut a bigger one and after some trial and error with the focus and aperture settings, here is the result. also the first circle was way to far away from the lens and the shapes were very blurry.
To summerize : cut a circle with the diameter of your lens. If you have a sun cap it holds the carton circles perfectly so you don’t need to use a tape to put them into place.
