In this article, I’d like to describe how to make sunuto with slave flash and available materials in 100 yen shop. Hikaru-Komachi, the light quantity doesn’t reach the studio flash, is slave flash that the position of them is fill light.
- Purchase slave flash
- Purchase the materials in 100 yen shop
- Assemble
1. Purchase slave flash
You can select slave flash from many choice. Hikaru-Komachi 2D requires two AA batteries and its guide number is 5 fixed. If you need larger guide number, you can select Hikaru-Komachi Di (GN 13) or other slave flash.
2. Purchase the materials in 100 yen shop
Required materials are following list;
- Plastic tape with wire
- Packing tape
- Stainless steel bowl
- Aluminum sheet for thermal insulation
I purchased plastic tape with wire at horticultural corner and stainless steel bowl at kitchen corner, respectively. Inner gloss surface is a reflector of flash. I purchased aluminum sheet at special event corner.
3. Assemble
Cut aluminium sheet to appropriate size and wrap it around the bowl, and fix with packing tape. The exact form of the aluminum sheet is fan-shaped. If you cut it into a rectangular shape, you don’t have to care. You can adjust the margin.
Cut the packing tape with length of the opening of the bowl and paste the plastic tape along the packing tape. The wire is for keeping the opening circular shape.
Paste packing tape with plastic tape around the opening of the column of aluminium sheet.
Put slave flash into the bowl. Finished!
Now, calculate the performance of the fill light. If you would shoot with medium-size or large-size format, you might set aperture of lens to 16 or 22. If you set aperture to 16 with GN 5, for example, you can get correct exposure with shooting distance 33 cm. If you use the sunuto as fill light, you have to close to 8 cm. If you use flash with GN 13, you can get correct exposure with 75 cm distance and fill light effect with 19 cm, respectively. The light quantity is not enough. You might set the distance at least 50 cm between model and sunuto. You might require GN 32 flash with aperture 16 and GN 44 flash with aperture 22, respectively.
