The white and lighter photo styling backgrounds are the most useful. White stands for pure expression, i.e. one without distractions and is therefore a good, basic background to work with. The white photo styling backgrounds are like a white canvas, where you can create your own style.
The white photo backgrounds vary in structure and shades and thus also in expression.
For example, the Less is More photo styling background has a blue-gray undertone that gives it a cool expression. The Simple White photo styling background has a yellowish background which gives it a warmer expression.
