Contrast and Fill Shadow

This exercise started off by looking at the effect of placing a diffuser between the a still life setup and a light source placed at 90 degrees to the camera.

The image below is taken with no diffuser:
Contrast and Fill Shadow-1

This image was taken with a diffuser placed on the flash gun:
Contrast and Fill Shadow-2

The lighting for both images was a remotely fired flash gun.

In the image where no diffuser was used, we can see that the reflection is much stronger then when the diffuser is used. It’s also evident that the adding the diffuser has weakened or reduced the light hitting the still life objects, something that is important to consider when adding a diffuser.

Following the above images, I repeated the exercise but used 3 different surfaces of a 5-1 reflector,  white, silver and gold, to bounce light from the flash gun back towards the still life.

Finally, I placed an amber gel over the flash and repeated the the experiment with the three different reflectors.

Final Thoughts

Experimenting with the different reflectors has been a good learning experience and it has demonstrated how using a reflector with direct and diffused light can fill in the shadows of a subject. The experiment has also shown that we can control the amount of light being reflected by either changing the distance of the reflector to the subject or by changing the reflectors surface.

Out of the three different surfaces, the silver reflector reflects the most light followed by the white and the gold reflectors. With the gold reflector, we can see how the colour of the reflected light is changed.
