One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them, One Ring to light them all, and in the studio blind them. A week ago I bought an old Profoto Pro-7 Ringflash on Ebay. Steven over in Denmark mailed it off to me and it arrived this morning. First thing was to check that it actually worked by shooting the dog. Ringflashes create a unique style of light that is popular for some types of fashion photography. If you look at Bear’s eyes you can see the distinctive ringflash catchlights. It can also be used as a fill light to make sure there are no deep shadows.
