Im in a bit of a different area of photography than the photographers on here that I know of, which is a commercial set, product and jewelery studio.
We do things from Mark & Spencer's bedding, a lot if not all of Jacamo stuff, JD Williams, to all of Topps Tiles (Ive developed an unhealthy hatred for tiles).
Im only assisting there atm, so basically building and rough lighting the set, then a stylist goes to work, then photographer takes the shot and edits. I have to do all the s**t jobs as well though but its starting at the bottom and working up to a photographers position. Its full time paid work though, with obvious career prospects in a couple of years, so Im happy with that for now, plus I do have a studio of my own for portraits, children, couple photography plus weddings, which takes up all my evenings and weekends but at least I'm the photographer on those.
I only heard about a job going there through word of mouth, these kinda jobs dont really get advertised. From my experiences, the advertised ones are the jobs that dont pay, pay very poorly and you end up out of pocket or its hardly worth doing unless you are at the very start and want the experience. Some of the photographers here don't believe me when I say I have been working for basically free for a year before finding this job, its just that so many people want to do it, but if you really want it then you have to do the unpaid now to gain experience and the money will follow.
Depends what kinda of work you would like to do in the end? No good, taking pictures of birds and landscapes if you want to work in a set building environment.
