If the instability of the freelance photographer’s way of life isn’t for you, you can always find a day job that involves traveling. Then you can go to lots of places, be paid for it through your job, and do travel photography in your spare time. Jobs like flight attendant, global salesperson, English teacher (or a spy!) are just several of many professions that let you visit your dream locations, without being too risky on the financial side.
A pretty picture is not enough. It needs to be high quality and it needs to be original. For magazines, you need to consider issues such as leaving space on the image for word placement, positioning your subject off-centre so it doesn’t fall down the page join, and possibly placing the subject on the right-hand side of a landscape shot for maximum impact.
