DIY Star Filter

Step 2 Cut it, fit it, tape it

First, you need to figure out how big your lens is so you know how big to make the filter. The easy way to know if you need the can or the empty tape is to slide the Pringles can over your lens if it's too big than that's what you'll use. However, if its too small try the tape.

To give you a basis of comparison my lens is 58mm and the can was too wide, so the can can accommodate a lot of lenses. The original by Rey Nocum was made out of an empty tape roll and his lens is 85mm (googled the model number on his lens hood)


Once you know what material your using, cut a strip of the container about a half inch thick or so (if using an empty tape roll it might be narrow enough already).

See it it will slide into the lens hood, if it's too big, as it should be, then cut out a small section and try fitting it again. You could measure it and cut once, but guessing and checking is probably faster.

Once you have it at the right size seal the seam with a piece of tape.
