Hey! I am a fairly new photographer and have been checking out lots of different images. There are particular images that I like where it seems that the photographers are actually holding a light above the subject so that just a small area is lit up. Then at a wedding once I saw an assistant holding what seems like a flash on a pole above the subject and was wondering if this was how they got that look. If so, where can I buy those sticks to mount my 430ex on? Thanks!
