Homemade gridspot diffuser. Gridspot (or grid) is a studio flash accessory. When the flash fires with the grid the spread of the light rays is limited.
The effect you receive is very similar to the effect obtained is a more controlled light and it reaches only a part of the surface to be photographed.
The inspiration for this article came from an article from the Blog Strobist, which alias is a great blog, which shows how to make a homemade gridspot cardboard.
Here’s what you’ll need:
The first step is to measure the head of the flash. For this article was used a Nikon SB800, which is six inches wide.
Next using the stylus cut the polyonda plastic into six-by-three pieces. If you want a home gridspot with greater depth no problem, the greater the depth the greater your influence on light.
The next step is to glue the polyonda parts on top of each other. Make sure that all “tunnels” are aligned.
When you’re done you must be with something like that
Now the cat jump. Try looking at a light source through your new homemade gridspot, you will notice that at only one angle it allows you to see the light.
This is exactly what happens when you put your homemade gridspot, and also the non-homemade ones, in your flash. The light comes out at only one angle and not spread everywhere.
Now just use an elastic band to hold it to the head of your flash
Here are two images taken in exactly the same way with a single change – one has a homemade gridspot and the other does not.
You can also make one of this with black straws and a box made of cardboard! What is easier!
