How appropriate. This is a simple product shot done with a digital SLR. The camera is at 45deg.
3 strobes. two softboxes left and camera right with edges close to lens. One gridded flood pointing to the white background under the table level. First set with the Sekonic L-758dr light meter, and the 24-70 f2.8 Canon lens. I know, I upgraded.
Incident dome metering pointing at camera on the near corner of the box. Shutter speed 125th.
-1 all lights: f5.6 Each soft strobe: f4.0. Background f1.2 Shot at f4.5
-2 all lights : f16 Each soft strobe: f11. Background 2. Shot at f14.5
The background measure just shows that there is little spill to the front of the beer pack. The intensity at the background remains the same, it meters f32.5 for the second configuration , 1.5 stops above the midgray at the pack.
Note: the smaller aperture shot is colder by 300k. I corrected with Lightroom.
The whole exercise is about learning to control the depth of field and using minimal postproduction re adjusting. The fun part will be to compare with a 4x5 shot with tungsten lights that I have lined up. Stay Tuned....
