I was introduced to the idea of shaped apertures while researching Lensbabies. I then found this
link almost six months ago. Tonight I finally made some shaped aperture cover things. The shapes of the little covers turns anything bright and out-of-focus in your image into the shape cut out. Most people do hearts.

You will need black cardstock (I only had colored...), scissors, a lens, a compass, a ruler, and a pencil. |
|
The size of the shape/hole you cut out is dependant on the lens you use. The way to determine the size is to take your focal length and divide it by your maximum aperture. In my case I have a 50mm lens with an max. aperture of 1.7, so the hole can be no bigger than 24.4mm.
 |
My first shape is a square, inspired by a 80s Volkswagen Jetta ad. The front of your shaped aperture cover has to be big enough to fit over your lens. |
|
 |
This is the square one completed and "mounted." The ugly black was my attempt to prevent light coming in the sides and ghosting. My later covers have "hoods" to cover the gap. |
|
 |
This is my triangle cover. As you can see the "hood" looks a lot better. This size of the "hood" is the perfect length as too long and you loose the shaped bokeh effect. |
|
 |
This is my asterisk cover, inspired by the meter-lock indicator of the camera it is on. The "hood" on this one is a tad too deep. |
|
 |
Here they are all together. |
