The pop-up flash on your camera is convenient.
But—the light it produces is ugly.
Pop-up flashes produce:
1) Dark shadows with distinct edges.
2) Small, overexposed highlights, on faces and objects.
These areas of glare are called hot spots.
Pop-up flash light is appropriate only for Weegee-style photography, not for people and still lifes.
Pop-up flashes produce dark shadows and hot spots because the light source is small.
The solution is to make the light source larger.
Several manufacturers make devices to enlarge the pop-up flash.
Larger light sources, compared to smaller ones, produce:
1) Brighter shadows with soft edges.
2) More diffuse highlights.
Below, the LumiQuest Soft Screen makes the flash bigger with a diffuser.
The Lightscoop makes the flash bigger by bouncing it off of the ceiling.
