I think one of the biggest mistakes people make when moving into making photography a full time job and business is being a general photographer. We all enjoy photographing range of images as I am sure anyone with a keen interest in photography who is carrying on to go pro has explored shooting a range of genera’s and styles. However, presenting a portfolio of work that is not cohesive is only going to confuse people when you are first trying to secure clients and establish yourself as a pro. It really doesn’t put confidence in anyone seeking a photographer if they are seeing a smattering of imagery as people like to hire photographers that are demonstrating to them that they are very good and consistent at the style or type of image that a client is seeking. At the very least only present suitable work in line with what a prospective client is looking for. First impressions here are important and you will want to separate yourself from others who are competing for the same clients. Once you have become well-established in one genera of photography and perhaps in a distinctive style and are generating solid and steady earnings then you can expand and show a broader range of work.
