First I show you the materials I used for this tutorial. First of all the LED lights.
Second we need some thick card board, I cut some pieces out of an old box.
Now take your camera and a pen. Put your camera with the lens down on the cardboard and trace the lens, this part needs to come out so the ring light will fit on your camera.
Now you need something which is round and bigger to draw the outside of your ring light. I used a small plate which fitted perfectly. Put it on the card board and trace it, make sure your first circle (the trace of the lens) is in the middle.
I marked the middle of the circle of the lens so it is easier to place the plate for the outside circle.
Now take your scissor and cut out the outer circle.
Take your knife and carefully (don't hurt yourself!) cut out the inner circle. Don't make your hole to big yet.
When done try to fit this over your lens, if it doesn't fit yet you can cut out a bit more until it fits.
When the middle hole is big enough it should fit around the lens and look like this.
"Happy Birthday" has got 13 letters, but it easier to devide a circle into 12 parts so I decided to go for 12 lights in my ring light. (this looks aesthetically better too in your final photo because they are nicely devided in the circle). The 13th letter we'll hide behind the ring, you wont see it in later on.
You can start by writing the numbers 1, 4, 7 and 10 on your ring, they each make up a quarter part of the circle. Now devide each quarter part in 2 equal parts and you have your 12 markers where the lights are suppose to come.
Now take your scissor again and with one point of the scissor make a small hole on each number you wrote down. Don't make them too big because the lights need to go in here, you can always make them bigger later on.
When done with all the holes your ring will look something like this.
Now take your "Happy Birthday" chain and take of the plastic letters, you'll be left with a nice chain of 13 LED lights.
Take your ring and, 1 by 1, put 1 LED in each hole. In my case I'm left with an extra LED but that will be on the backside and won't be visible in your final photo.
If you turn your ring around you'll see the front with the lights sticking out.
Take your camera and place the ring light around the lens. It might look weird but it's the end effect that counts.
You are ready to test your new homemade ring light!
See: the endresult looks great! You too can make those awesome shots with reflecting ring lights.
