some folks require years of education and instruction, some of us taught ourselves... at teh end of the day its your portfolio which sells you.. not your quallies...
i dont have a degree, but now i do have 35years experience... my diary is full... but it wasnt always easy.... in reality you have to have a niche', you must offer them something which set your imagery apart from johnny next door... actual photography is relatively easy, however creative consistent imagery isnt.. develop those skills, and youll never be out of work..
35yrs ago i was a grunt, with a camera, and lots of gung ho enthusiasm.. i did the whole lot, from models on catwalks, to scars on compensation victims... from births, to funerals... now i teach... and i work on teh principle, youre only as good as your last job...
so, build a portfolio, A3 is best (12x16)... its got me my first non photographic job, which was compiling a magazine, doing pagelayouts and creating advertising storyboards...
luckily i can write copy, and i have a style, which is quite different... and the clients like it... 8yrs later, im the editor... and a director of the charity, where i also teach...
im not famous, im certainly not rich... but im happy... and in this day and age, thats a major bonus, believe me.
