When you shoot indoors, you often find yourself in situations where you don't have enough light to take good and sharp pictures.
You then quickly have to adjust the ISO value, exposure value or shutter speed of your camera, with all the consequences that entails.
One way to counter this problem is to use a flash (internal or external). Unfortunately, flash light has the disadvantage that you cannot often illuminate everything within a room evenly. In addition, there are often unwanted reflections.
These drawbacks are easily solved by using a diffuser, which you can buy in many shapes and sizes.

This diffuser is suitable for the internal flash

Info :
Diffuser for internal flashes (SLRs), which you place on the hot shoe of the camera.
With this flash diffuser, for built-in flash units, the direct flash light is nicely softened, so that detail in highlights is preserved and skin tones are reproduced realistically, something that is problematic with flashes without a diffuser.
The diffuser is also a problem solver for macro shots. As easy as it is to apply, it is as easy to take off.

Features:
 Almost all SLR cameras with internal flash.
