Exercise 38 Concentrating Light

This is an exercise in concentrating light. I tried two techniques.

Honeycomb Grid

This shot used the same “colour box” as described in exercise 37. I placed a flashgun on a thin plastic grid diffuser over a hole and directly above the subject.

In fig. 02 the only difference is the addition of a reflective black acrylic sheet beneath the subject which bounces a small amount of light into the shadows.

Fig. 03 Broken Egg - diffused flashgun directly overhead through hole in colour box at 1/64 power and honeycomb grid by camera at 1/4 power - 1/60 at f/16, ISO 100

For the final example using a honeycomb grid I have moved the flash gun with the grid to a position by the camera and placed a diffused flash gun at lower power directly overhead.

Snoot

In fig. 04 I have used a snoot on the flash gun by the camera. There is just enough light from above to show the tomato at the back but the snoot is concentrating the light on the front faces of the subjects.

Fig. 05 Tomato - flashgun with snoot by camera at 1/2 power - 1/60 at f/16, ISO 100

In the final example there is only the one light, a flash gun with snoot to the left of the camera.

Conclusion

A useful exercise that made me think about how to use a snoot and a honeycomb grid. For these type of subjects they offer interesting effects. I particularly like the grid from above as this emphasises the colour of the fruit and brings out interesting shapes and forms by casting such strong shadows.
