DIY Gary Fong Lightsphere
Artur designed his diffuser for normal speedlites, the head of which can swivel. I must say, this design works very well! Please refer to Artur's article for the materials required.
Looking at the Fujifilm EF-20, which accompanies my X100S, things start becoming different.
First of all, although the EF-20 allows to tilt the flash 90 degrees upwards, there is no swivel possibility.
Secondly, the EF-20 is slightly tapered towards the business end.
So, I adapted the dimension as follows:
- length: 23.5 cm
- width: 12 cm
The constraint here is to employ an aspect ratio and orientation similar to the sensor in the camera, since the EF-20 does not swivel.
Since the flash is tapered, it is important to get as much friction as possible between the flash head and the diffuser. The rubbery material of the EF-20 is a good help here, since it is pretty sticky when used with the smooth side of the silicone lining material. The knobby side provides essentially no grip at all.
When building the diffuser, you hence want the flat/smooth surface inside. This might actually help the light bouncing inside the diffuser.
To mount the diffuser on the EF-20, you want to mount it on the front part of the head first and then slide it back to obtain good grip.
All in all, the first result look pretty promising!
A new addition to the bag, which easily fits into the bag's tablet compartment.
