Step and repeat
A step and repeat banner (sometimes a step and repeat wall or press wall) is a publicity backdrop used primarily for event photography, printed with a repeating pattern such that brand logos or emblems are visible in photographs of the individuals standing in front of it. Step and repeat banners are common fixtures of red carpet or fashion events, or custom-printed for weddings or galas in order to give a more "celebrity-like" feel to attendees' photos. 
Step-and-repeat backdrops can be made in several ways. The most common ways are either vinyl, fabric, poster paper, canvas or adhered onto a hard substrate such as plywood or foamcore. Recently step and repeats have been created with greenery, called 'green step and repeats'. Each has its own sets of pros and cons. Fabric is less likely to have hotspots in photography which means it tends to absorb a flash rather than reflecting it. Vinyl is heavier duty and sometimes has brighter, more vibrant images. The support structure can vary depending on size. Standard Trade show display frames are often used, or it can be hung from or applied on a wall.
The main use for step and repeats is brand awareness. Vendors may charge a sponsorship fee for a logo to be displayed or for the company name to be featured in the background. The idea is that the photos will be shared through various platforms causing a ripple effect in impressions. More recently, step and repeat banners are being used more widely in and not just for hollywood style events. They can also be seen at trade shows, conventions, demo days, grand openings and even weddings, birthdays, and Apostolic Pentecostal church events.
