Technical Workshop Week 5
22:00
Controlling light week 1 of 2
The purpose of todays workshop was to evaluate the use of flash and ambient light.
We set up outside and set up our camera's ISO and white balance to fit with the conditions, and set up the ranger flash kits.
Task One involved using flash. We set the cameras shutter speed to 1/125; its maximum flash-sync speed, and our light meter to flash mode. We determined an aperture by taking a 'flash' incident light reading, which was f/22. This was the outcome:
The use of flash here gives the effect of darkness with only the model being lit. This is because we underexposed the ambient light; the correct shutter speed for a correctly exposed image at f/22 would be 1/4 of a second. However our shutter speed was 1/125, under exposed by 5 stops.
Task Two involved mixing both flash and ambient light. We set our aperture to f/8 and took an incident light reading and used the shutter speed given which was 1/15. This was the outcome:
This image mixes both flash with ambient light.
Task three let us get creative with the flash. We decided to mimic a technique which Andy Earl had shown us which he used in his early college work where he used multiple flashes to capture the foreground in focus and then blur the background. We only had a single flash to play with so we took an image with flash and then jolted the camera; This captured the subject and blurred the background considerably.
As your aperture gets smaller (f/5.6 to f/11) the image will become less exposed (darker)
As your aperture gets wider (f/11 to f/5.6) the image will become more exposed (lighter)
