Use soft, diffused light rather than a direct on-camera flash or bare lamp. Glare on shiny LEGO surfaces is usually reduced by making the light source larger and softer—try window light through a curtain, a light tent, or lamps bounced through white paper or fabric. Move the lights and camera angle until reflections fall away from the most important surfaces.

A few other helpful basics:

• Use a simple, uncluttered background.
• Put the model on a stable surface and use a tripod if possible.
• Use a low ISO for cleaner detail.
• Stop down a bit for more depth of field if the whole model needs to be sharp.
• If color looks off, set white balance to match your light source.

For close shots, avoid shooting too wide and too close, which can distort the model. A slightly longer focal length and a bit more distance often gives a more natural look. Take several test shots while adjusting light position, because small changes make a big difference with reflective plastic.
