You may fit honeycomb grid on the diffuser of soft box or light bank.
Soft box and light bank convert point light of speedlight into diffused surface light. Then the hard shade of the subject with speed light alone is converted into soft shade and the sharp shadow falling on the background is converted into mild shadow, respectively.
Honeycomb grid converts a surface light into convergent light with adding directivity, smooth a shade of subject and make the border of shadow unclear, respectively. As the ratio of the height of the grid to the area of the grid is greater, the light more converges with directivity. As the ratio is smaller, the directivity weaken and the light quality approaches to the diffused light.
The beam of the light from each grid diffuses on the subject. As the grids are arrayed offset each other, the beam with shifted optical axis reaches to the subject. As a result, the amount of light overlapped on the center of the surface becomes almost uniform, but on the peripheral area around it becomes gradually dark.
As the distance of the subject from the light source is longer, the shade becomes unclear and diffused and the area of diffuser becomes small from the point of view of the subject, the light quality approaches to point light.
Since the aperture of the honeycomb grid with straw is circular, you can’t use enough light. In this article, I’d like to describe how to cut out the honeycomb grid from a sheet of paper.
Since the guide number of Hikaru-Komachi is only 13, you can’t use in the field. I’d like to describe about honeycomb grid, it’s assumed to use of speed light with larger guide number and to attach to handmade soft-box. You should take care of flame with overheat because it’s made with paper.
In order to cut out a regular hexagonal grid from a sheet of paper, you have to draw a developed view as following;
Regardless of the length of hexagon, the length of the long side would be three quarters of the original. The length of the short side depends on the thickness of the grid. Irradiation angle depends on the ratio of the thickness of the grid and the length of the sides of the hexagon.
Materials are bellow;
- Black Kent paper (A4)
Although you can purchase black Kent paper in Amazon, it’s too many to use with individual. You should purchase it in art supply store.
Put the cut with a cutter knife and ruler and crease with ruler. Be careful because valley fold and mountain fold would visit alternatively.
Glue the opposite sides of the valley fold. You would understand the side to glue when you crease.
