Most flashes include a built-in diffusion panel that flips out to cover the flash. This translucent panel softens the harsh light output by spreading the light rays produced by the bare flash bulb along the surface of the panel to more evenly distribute illumination as light rays move forward. Although the amount of overall light is reduced, as is the case with all light-modification tools, this results in better overall illumination, less contrast and reduced shadows. In essence, all diffusion solutions work in the same way as a diffusion panel, only more advanced diffusion solutions like softboxes, domes and hanging fabrics or silks give more advanced possibilities.

Available in a variety of shapes and sizes, including strip lights, rectangular panels and larger studio models with a lot of surface area like octaboxes, softboxes are the most popular diffusion accessory in photography because they soften light through a large front panel to achieve especially flattering light similar to the natural diffusion that you find on a cloudy day. Miniaturized softbox solutions for working directly with a speedlight are available whether shooting from the camera or mounting your flash to a stand.
