If you intend to get into freelance photography full time, you need to be aware of what lies ahead of you. One of the biggest mistakes people make is to decide they want to be a 'full time' freelance photographer without realizing that it is certainly no 'easy street' to success. In fact, it is a full fledged business that you're going to have to run!
Essentially, as a full time freelance photographer the focus of your activities will be on one thing: Profit. What you need is to make enough money to cover your costs, pay the bills, and still have some left over for other expenses. After all, your freelance photography is going to be replacing whatever 9 to 5 job you've had in the past, and so it needs to be able to help you make ends meet.
With that in mind, your photography is no longer going to be about taking pictures of whatever you feel like taking pictures of. Instead, the bulk of the time you spend on your freelance photography is going to be focused on figuring out exactly what areas of photography will help you to make the most money. Needless to say, you're going to have to advertise and market your work, your availability and your services to as wide an audience as possible!
Knowing that this is the truth about freelance photography should help you to dispel any of those 'romantic' notions that you might have had about being a freelance photographer.
The truth is that freelance photography can be a great occupation -- but you need to treat it as that and not a hobby if you intend to get anywhere with it!
