Imagine a vibrant flyer template for a summer event. The scene is bursting with the energy of summer, featuring elements like a sun-soaked beach, colorful beach balls, and a lively crowd. The style should be reminiscent of the vivid, saturated colors found in the works of pop artist Roy Lichtenstein. The lighting should capture the golden hour, with the sun casting long, warm shadows. The color palette should be bright and cheerful, with a dominance of blues, yellows, and oranges. The composition should be captured with a Canon EOS 5D Mark IV DSLR camera, using a wide-angle EF 16-35mm f/2.8L lens to encompass the whole scene. The camera settings should be set to an aperture of f/8, ISO 100, and a shutter speed of 1/125 to capture the dynamic scene in sharp detail. The image should be post-processed to enhance the colors and add a slight vignette for a vintage feel. Render this image in photo hyper-realism, highly detailed, and high-resolution 16k.
