V Flat Lighting 00207 v2

In part 1 we demonstrated how to use v-flats to provide indirect lighting for small objects such as flowers.  Now I will show how to use v-flats for setting up a shot with objects made from glass.  Reflective objects such as glass and stainless steel are more tricky because the object will show to the camera whatever is reflected on its surface.  So what we need to do is add black or white surfaces near our glass object to create pleasing reflections that we want to see.  We can also use surfaces to shield lighting to give us rim lighting.

Here is the setup:


This time we use big floor standing v-flats and instead of flash lighting use a studio LED light.  A white v-flat is positioned with the vertex in the center, behind the the subject.  The the studio lamp is located just behind and below the subject pointing into the v-flat (opposite direction of the camera).  Similar to the flower photos, a foamboard "roof" is placed on top of the v-flat to further direct the lighting.  This part of the setup provides the background and body of the glass, but will not provide edge detail and 3D shape.  For that we position a black v-flat to each side of the object in a way that also blocks some of the light from the white v-flats.  This will give a black reflection to create the edges of the wine glass.  A black board is also placed to block the studio light and to provide a black reflection for the bottom of the wine glass.  The wine glass is positioned on a sheet of acrylic on a small stand with a piece of white paper underneath.  This provides a virtual table which is reflective.  The paper underneath the acrylic is long enough to droop down in front of the stand such that it provides a disappearing foreground.  Placing the wine glass at the rear edge of this "table" creates a different effect than at the center.  All of this requires some playing around to get the effects one wants.

For  something completely different, we can replace the white paper under the acrylic sheet with black foil or black paper.  The white foamboard "roof" on the v-flat is replace with a black one and a black background is draped behind the wine glass such that it takes up the field of view but still allows light on either side. 


Here is the result:

As you can see - it's fun to play with v-flats!
