Lighting and camera setup

1. The lighting

3DSOM Pro can handle photographs taken under a variety of conditions. Several typical configurations are shown below - a low budget desktop photoshoot, a professional studio set-up and a lightbox with turntable.

3DSOM Pro will automatically correct many lighting problems, although the following points should still be observed:

Lighting advice for professional studios
  • Use diffused lighting to flood the scene with even lighting
  • Use a reflector above the object
  • Minimise shadows from the object

2. Camera setup

Key points

TIP:

Try to make the object and mat fill the camera viewfinder (i.e., make good use of the camera view space) to improve the quality of the results.

Tips for more experienced photographers
  • Experienced photographers should use the camera in manual mode. Use manual exposure and F-stop to ensure all the photographs are taken under the same conditions.
  • Use as large an F-stop as possible in order to increase the depth of field so that the whole object and calibration target(s) are sharp and in focus.
  • Experiment with the exposure settings until the correct image is achieved or use a standard grey chart or light meter.
  • You can adjust the white balance manually to prevent white balance unevenness.

3. Projector setup

Key points

TIP:

The slides folder includes vertical stripe patterns which you can use if your projector is rotated 90 degrees. e.g. for projecting on a tall object. There are also "fine" versions with thinner stripes - only use these if the thin stripes appear distinct (sharp, in focus) on the object.
