DIY Beauty Dish

Materials: 18" steel bowl, CD, convex automotive mirror, L-bracket, Black spray paint and white primmer, 1/4 bolts.
 CW from Left: From a steep angle the strobe has a direct line of sight out, but because the lens on the strobe directs most of the light forward the stray light from this steep angle isn't too much of an issue. The backside shows the convex mirror through the opening. Looking at the face, some spill light from the back side is cast on the wall, but I think a little felt or weather-stripping baffle around the opening of bowl would help mitigate the spill and protect the strobe housing from being scratched. The first of the last two shots shows the dead spots and subsequent spill near the edge of the light field indicated by black arrows. The white arrows show shadows caused by the bolts that support the internal reflector. The final image shows how by moving the internal reflector in and out, the light field can be "tuned" to have a smooth drop off.


Direct flash vs. the Beauty dish. Notice the shadow on the wall.
