Background and environment
How to choose a readable background and an environment that does not distract from or distort the item.
A simple background keeps attention on the item.
A clean wall, plain fabric, large sheet of card or lightly textured surface generally works better than a visually busy room.
Pure white is not required. What matters is sufficient separation between the item and the background.
A very light instrument may be easier to read against a slightly darker background, while a dark item needs separation from a dark backdrop.
Avoid strong patterns, highly saturated colours and reflective surfaces that compete with the subject.
The perceived colour of an item can change because of reflections from the environment.
Strong red, green or blue walls can contaminate glossy surfaces. The same can happen when light sources with very different colour temperatures are mixed.
If colour is important for identifying the finish or variant, use a reasonably neutral environment and consistent lighting.
A listing photo should help the buyer understand the real colour, not create a more dramatic but less faithful version.
