I recently posted a video showing some of the flash equipment I take on certain assignments. The video showing some of the additional items such as Morris Mini's were used here.
First I will tell you that I used a total of 4 lights in this very small location at a lab in Ohio.
Let's first look at the reflection in the glassware at the left of the frame. I used a Vivitar 283 with a blue gel over the flash head with a small softbox attached to the head of the strobe. This strobe was held in place with a Bogen type (Avenger) clamp & flexarm. I had a slave plugged into the strobe which allowed it to fire when another flash in the room went off.
For the main subject, the technician was lit with a single dyna-lite head with a grid on it to contain the light from spilling all over place. The orange light behind the glassware just to the right of the technician was created using a morris mini with an orange gel. I simply taped the strobe to the wall in the corner of the venting hood. The mini fires with the use of a built in slave on the flash. One 4th light gelled with blue, was bounced into the ceiling to the right of the technician to fill the upper right corner of the image with color.
