What Is a Diffuser? Diffusers are the vent covers through which climate-controlled air is delivered to a room.

What is a diffuser in ventilation?
A ventilation diffuser disperses pressurised air exiting heating ventilation and air conditioning ductwork and provide a decorative finish over the grill box hole holding the ductwork in place. Without an air diffuser, the air exiting the HVAC system would travel in a straight direction.
Does temperature increase in a diffuser?
Supersonic Diffusers A supersonic diffuser is a duct that decreases in area in the direction of flow which causes the fluid temperature, pressure, and density to increase, and velocity to decrease. These changes occur because the fluid is compressible.
Can I use the MT-24EX without a diffuser?
That’s about the only good point of using the MT-24EX without diffusers. The light tent diffuser is two pieces of Vellum paper kept about 20mm apart, and mounted on the end of the MT-24EX flash ring that attaches to the end of the lens.
What is a light tent diffuser?
The light tent diffuser is two pieces of Vellum paper kept about 20mm apart, and mounted on the end of the MT-24EX flash ring that attaches to the end of the lens. The diffuser is large enough so that the flash heads can be positioned 90° apart while still both shooting through the diffuser.
Which diffuser for the canon MT-24EX macro twin flash?
In April SteB designed some new diffusers for the Canon MT-24EX Macro Twin Flash (which I use) that have a concave design. He described them and posted some comparison shots on the Juza Nature Photography Forum: Concave Flash Diffuser Test. Also mentioned on that thread is a ‘light tent’ diffuser, which seemed to produce excellent results as well.
What is the front of the diffuser made of?
The diffuser is fronted with a piece of Vellum paper. The flash head with diffuser attached was mounted on a Kaiser Adjustable Flash Shoe to elevate it above the subject. The long length of the diffuser means that the end is positioned relatively close to the subject, making for a larger apparent light size (and so better diffusion).
