As photographers, many see assistants as superfluous, expensive, and reserved for those at the highest end of the photography career spectrum. But it could be exactly the move that will help your photography business grow past where you can get it alone.
I'll be honest: I don't use an assistant for every shoot. In fact, for a number of years I didn't use one at all, chalking it up as all the things above. I didn't believe my profit margins to be high enough to get an assistant, and in some cases I was right. Then I had a shoot which felt bigger than me at the time. It was my highest paid shoot at that time (which wasn't saying much, this was relatively early days for me) and I was more concerned with delivering great results than the profits I made. So, I hired an assistant for the day. The shoot went fantastically, and although I did lose some of the money by hiring an assistant, it wouldn't have gone so well without one. Furthermore, I secured more work off the back of the results of that shoot.
In this video, Karl Taylor discusses why a photography assistant is crucial to growing your photography business, and it's difficult to refute. I would hire one for every single shoot I do if it were possible and convenient. They are an investment that pays in dividends that are difficult to see until you pull the trigger the first time and hire one. An assistant can easily improve the quality of your work, the pace of your work, and the smoothness of your workflow.
