You can experiment with different backdrop ideas to make the photos more vibrant. For instance, you may use colorful party streamers for a striped backdrop. You can also explore beaches, gardens, or urban landscapes. Alternatively, you can tape different paper plates in random colors on the wall or drape fairy lights over a curtain rod for a fairytale-like background. Finally, you can cover the lamps or lights with tulle and add some fake flowers to the top for more impact.
