Something I did when I started out at home... I saved to buy a good secondhand/used flash head (A Courtenay 1600). This I used as a main light and I filtered the light of with thin material (muslin) stretched and stapled across a wooden frame I made up from light timber. I also bought a medium size foldaway reflector and grabbed as many white sheets as I could. For a hair light, I would use a mid range flashgun with a zoom head, connected to a slave cell and mounted on a cheap tripod. I made a snoot from fastening thin card around the head of the flash with rubber bands. (OK if the model was sitting or laying, but had to improvise for standing shots). I would also use a couple of "cheap" small flashguns, wih slaves, and fire them into the reflectors/sheets to creat some reflective light. All this is ok, but would only allow fairly close up portariats, as the "lights" would have to be fairly close to the subject to get the details. Thats how I started. Makeshift, I know, but the results were surprising (and I sold some too) I made enough to upgrade to a three light set. Alas, they have now gone, but I am lucky in that I have access to a studio. Hope this helps!! :) Dave
