A single query I obtain in my workshops for beginners is about flashes. Notably “What the heck is this for?”

And, “Does it actually do something?”
Not all flashes have these two objects that cover the flash head and pull straight out, but if yours does and you’ve constantly wondered, right here is your answer.
These two products each serve various purposes. The 1 that flips more than the flash itself is a diffuser. Its task is to spread out the light from the flash. You might have seen larger diffusers, such as a softbox over a flash. Individuals diffuse even a lot more light than this piece of plastic. But it really is far better than practically nothing when it comes to spreading out light. At the same time you flip out this contraption, your flash will typically back up the light supply within of the flash unit (if it has zoom capabilities) to help project a broad swath of light.
These two actions function hand in hand to spread light and not make it so tight on your topic. The final piece of plastic, the far more opaque one particular the at sticks out straight, assists bounce light that would have bounced away from the topic, get pointed back just a liiitttle bit much more in the direction of your target. This can be beneficial when even more diffusion is desired, or if the flash is currently being bounced off a ceiling and some catch light is wanted in the subject’s eyes.
Let me display you the variation a diffuser, coupled with the bounce plastic and a wide zoom in the flash, can make.
This first shot of a f-cease Gear Satori pack I was reviewing is taken at 85mm and a distance of about eight feet. This shot is taken with the flash pointed straight at the pack and coming in from the left side as I have tilted the camera, as I did not want to bounce the flash against a colored wall and couch.

Notice the harsh shadow to the side of the pack brought on by the flash? This is simply because the flash is coming from the side and is comparatively close. That shadow is caused by the pack becoming another eight feet from the wall behind it (as your topic gets additional from the background, the shadow will improve).
Now let’s attempt it with the diffuser in area, the bounce in spot and the flash zoomed back to 14mm (all of which happens instantly when I pull out the diffuser).

The exposure settings on the camera are precisely the very same in each images. The big difference need to be clear, that the second shot has significantly lighter shadows as effectively as a softer light on the pack itself.
The influence of this approach is significantly less pronounced when zoomed in further and the flash is now positioned over the camera in a horizontal orientation. Can you tell which shot is which in these two examples?

The clue is in the slight alter in the quality of light. Due to the fact the diffuser’s light is not as intense as the straight flash, it makes it possible for in a bit a lot more ambient light and this can be noticed in the initial picture as a slight a lot more orange is exhibiting (from the overhead tungsten lights). The reflections on the buckle are also slightly significantly less harsh.
Utilizing this fast and simple diffuser which you will by no means leave at house can have its positive aspects. It is not mean to substitute a accurate softbox, but it will assist when 1 is not all around.
