Show front, rear and sides when they add information

After the main view, photograph surfaces that are not visible.

Depending on the item, useful views may include:

• rear of the body;
• back of the headstock;
• rear panel;
• cabinet sides;
• underside of a pedal;
• rear connections;
• bottom surface;
• edges.

Keep a similar distance and camera height between shots where possible. The image set will then be easier to compare.
