I'm interested in taking portraits of my children, nothing professional. Looking at the B&H website regarding Smith-Victor lighting kits (they seem reasonably priced), I am uncertain what types of kit I should consider. http://www.bhphotovideo.com/c/search?Ntt=Smith-Victor%20Kits&ci=15293&N=4291216824+4294205295 There are tungsten, quartz, lights with umbrella reflectors . . . so many choices to boggle the mind. Just how many lights do I need and what type?
