Recently I have read post about short and broading lighting. Can someone explain the difference in the two and post examples. Also, can this be accomplish with 1 studio light? Also, what would be the positioning of the light or lights? I eventually want to get at least one studio light to begin with and would like to learn about lighting before I do. If this has been discussed before please point me in the right direction. I tried a search but gave up Thanks in advance.
