Background

• Ensure your backdrop is clean and uncluttered.
• Blank paper is a good option for a background, but check that it is a large enough piece that will fills the camera's field of vision ensuring your model has a clean smooth background.
• Blank walls also work

Lighting

• Light sources can be as simple as a phone torch, flashlight, or desk lamp. Taking your model outside and photographing with the sun is also a great option.
• Experiment with taking photos in a dark space with a one (or two) direct light sources, like a desk lamp.
• Practice positioning your light source at different lengths from the model and angles to observe the shadows and highlights created. This is useful if you have windows, openings and skylights/roof lights in your model and wish to show how light affects the interior space of your design.

Scale

• Whenever possible, include scale figures in your model to give the viewer a sense of how large or small your design is. 
• Try to bring your camera down to the height of one of your scale figures so that the photos appear to be "inside" the structure.
