From then on Peter worked for all major papers and advertising companies from his photo studio in Hamburg, Germany. Companies such as KODAK, AGFA, ZEISS, BAYER Pharmaceuticals, and POLAROID where his new clients. For many years he also shot 10.000 covers for Harlequin Romances. For all these clients he spent the next 15 years bounding around the globe and sleeping at least two thirds of each of those years in hotel beds. One such assignment Peter had been shooting in Los Angeles for AGFA Film. With three AFGA clients from Germany, three models from Paris and a crew of four from Hamburg they found themselves stuck in a freak storm in California. As the clouds went away, it left beautiful brilliant sunshine but also gale force winds on the beach where they were to shoot. They had to improvise as all of his portable reflectors were too wobbly in the wind and the shiny boards from the movie industry were to heavy and Geller did not want to hire a set of Grip people just to move and hold reflectors like in the movies. So in his hotel room during downtime the first prototype SUNBOUNCE was born and worked adequately enough to get the job done. With this success Peter set out to redesign his prototype and came up with the CALIFORNIA SUNBOUNCE (named for where it was born) SUN-BOUNCE PRO reflector which he then patented worldwide.
