Location Light Table

Location Light Table

As I look back at a past lighting/rigging solution, this topic covers a translucent subject (petri dishes) requiring light from below as well as from above.  Some used to call this “Hamburger Lighting”.

While shooting an annual report,  a topic on the shot list centered around growing cultures in petri dishes.  Spreading two tables apart in a meeting room and suspending a lighting grid (from the overhead fluorescent fixture) between two tables , I then slid a Lightbank under to create the light needed to come through the transparent petri dishes.

Two top lights were, a weak light bounced from the ceiling and a glancing accent light going across the subject from a low angle.

I wanted a lot of drama so used the “Less is More” idea, got close to a few petri dishes with the perspective of a wide angle lens.  Locations can offer unique opportunities for creative solutions!

Choices for Depth Of Field

Choices for Depth Of Field

Controlling Depth Of Field is a choice dictated by necessity for each situation.

Some choices:

1. stop down aperture

2. shoot image smaller and later crop in

3. use Stack Focus technique – needs post processing

4. use a perspective control lens – expensive lens

Example 1 – a small product – macro range

Here, stacked focus was employed.  Choices 1 and 2 were not best options.  With the camera locked down on a tripod, I used #3, successive exposures were taken with the focus on the front, the back and many steps in between – stacked focus.  The images were then processed to make one image for focus throughout the entire range.  I mark the focus ring on the lens at the front and back focus points with tape, so I know where to start and stop the successive exposures.

This is not a creative shot, but this image needs to be technically perfect for commercial use – tacky sharp from end to end.

Example 2 – location pizza pie shot

Here, a wide angle perspective control lens was used. Now this was a creative choice, for an “in-your-face” view of the pizza — I was positioned in close and over the pizza for a dramatic view.  (camera on a tripod side arm to get over the pizza) The lens was tilted to create the horizontal plane of focus, across the pizza, to the booth behind the set.  The key light was a boomed octa bank and the background light had a grid and red gel for the wine bottle and glasses. Tethered shooting allowed complex control.
