In this article Mohamed Talal shows us how to make a simple diffuser for a DSLR pop up flash.
There are three things that separate this diffuser from other diffusers we have featured before. The first is the total cost – this one really costs nothing. The second one is the size of the diffusion panel. By using this method you get a nicely sized diffusion panel. Lastly, a quick mod will turn this diffuser to a ring flash.
It is called the Headphones diffuser, but don’t feel obliged to use headphones casing, you can use GI-Joe’s casings, Transformers casings, or just a nice pieces of transparent material.
Start with the box of headphones, I got a Chinese headphone (from creative). The cost was 2.5 $. Again, you can use any leftovers from ay other “blister wrap” or semi hard transparency sheet.
Cut a round hole from the front piece. This hole is where the diffuser will mount on the camera.
Now make two holes as shown on the sides of the curves.
This is where the glue comes in. spread some glue on the surface side. Make sure you spread it nice (but thin). Once you have the entire surface covered, attach your diffusion material to the plastic. (We used printed paper in this tutorial, but you can use less absorbing material).
This is the time to use the back piece. Apply glue and attach the foil. The foil will make sure you are “wasting” any light. Any light reflected from the front will be bounced back to it by the foil.
Attach the front and back together. If you used anything other then head phones “blister pack”, attach your two parts together. Use tape or glue to make the two parts stick together.
Ok, we have made the bubbly thingy, but how can you mount it on the camera?
First, open your built in flash. Then, put the rubber thread under the viewfinder as shown in the picture below.
Now, place the diffuser on the flash as show in the image below. The rubber thread from the previous step will make the diffuser hold on to the camera.
Since we are absorbing a huge amount of light here, I suggest going manual and using 1/2 or full power. (Depending on your ISO and aperture, you may want to experiment a bit.
Wait, there is more! You can make a ring flash as well. There is one more additional step to convert this diffuser into a ring flash.
Use a round piece of foil and glue it to the diffuser. See the picture below for details.
…and here is an image with the ring flash attached.
