Where only a diffuser is used, the hardness of the shadow remains as is. Another difference lies in the effective flash intensity, aka the amount of illumination that reaches your subject, which is what really matters at the end of the day. A diffuser spreads the light across a larger area, thus resulting in a lower average flash power across the entire frame.
A softbox keeps the light largely directional. The subject still gets the majority of the light, but with a softer gradation from highlights to shadows. The result is that you get a flatter, dimmer image with a flash diffuser, while the softbox retains the contrast levels but softens the harshness of the light.
The main difference between a diffuser and a reflector is the extent to which they change the direction of light. A reflector mainly redirects light in one general direction, whereas a diffuser redirects light in all directions. The reflector is meant to provide a targeted source of fill light, whereas a diffuser is meant to bounce light all around. The reflector and diffuser are very different beings, and they work best when used together. When you only have a diffuser but not a reflector to bounce the light back onto the subject, you lose much of the diffused light to the surroundings.
When you have a reflector but not a diffuser, the reflected light remains a relatively concentrated light source that fills a particular area in the shadows, rather than raising the overall values throughout the frame. The wide-angle panel on your flash does appear to reduce hotspots and specular highlights, but it also reduces the flash intensity, resulting in a darker photo overall.
The panel merely spreads the light to illuminate a wider range without modifying the nature of the light. Turning up the flash power will cause the hotspots to reappear. The widest coverage for most speedlights is equivalent to the field of vision on a 24mm focal length, which is fine when shooting at a 24mm or longer focal length.
However, in some instances, the photographer might find the need to go wider than a 24mm, for example 16mm. This might be the case of shooting large groups within a tight space. The flash coverage will need to be widened accordingly, or else the people on the edge of the frame will not be sufficiently lit up, while those closer to the centre of the frame receives most of the illumination. But a necessary result of spreading the same flash output power across a wider range of subjects is that the flash intensity is lower across the board.
While it might appear that the hotspots have disappeared by adding the wide-angle panel, it is merely because the overall intensity has reduced. Should you need to turn up the flash output, the hotspots will still occur. Share this article on Pinterest too!

The Movo Flash Diffuser Set is an affordable, and versatile set that includes 3 different diffuser types — white for regular diffusion, gold for a warmer tone, and green to correct fluorescent lighting or create novel fill effects.
In addition to being portable, and affordable, these diffusers allow you to emulate natural window lighting for a beautiful natural look. The MP Series diffuser soft boxes works with all major external flash brands. Subscribe Sign up to get the latest on sales, new releases and more ….
The flashes we are referring to are external flashes, not the one built into some cameras. External flashes attach to the hot shoe the little bracket at the very top of your camera and synchronize with your shutter. They output light when you press down to take a photograph. Using a flash without a diffuser is equivalent to shooting a portrait in high noon soon, there is a lot of contrast and not in a good way! A diffuser camera flash creates softer light, with more gradual transitions between highlights and darks.
As such, it smooths out all of the contrast. Subsequently, it spreads the light and softens its intensity. Most new flashes have an accessory you can purchase known as a Dome Diffuser. These lighting accessories have a translucent dome that spreads the light and helps reduce the intensity.
The most common diffuser is a rectangular softbox. For flashes, these are mini softboxes to fit the unit. This is a three to a four-inch version of a studio softbox.
This attachment has a square sheet of diffusion material that sits over the light. If you need more of the light to spread, a sphere diffuser may be more your style. Sphere flash diffusers create a larger surface area for the light while offering a bit sturdier mount.
As the name implies, these diffusers soften the light by bouncing it. However, the downside is that this type of diffusion tends to lose more light than a sphere or softbox because of how they work.
