Strobelite PRO kit puts you in control of your lighting. Two 24" x 32" silver soft boxes with adapter rings allow you to wrap light around your subject while maintaining control. The internal baffle and outer diffusion panel are each easily removed, allowing you to go from soft, diffused lighting to high-contrast lighting without changing your setup. The included background light comes complete with a multi-function barn door set. This barn door enables you to control where the light goes, and just as importantly, where it doesn't go. Colored gels allow you to change the background color instantly. Each kit comes complete with a carry case and educational DVD. The educational DVD will walk you through numerous lighting techniques including portrait lighting, fashion photography, product photography, posing, camera techniques and more.
