I do make my living in photography, and it has taken many years to establish my reputation. I own multiple high-end Canons, 2 Nikons, countless lenses,etc. Put simply, when half my gear is in my new car, it's worth more than the car!
However, three ways I got to this point, Buy a good middle of the road Dslr
(exchangeable lenses, you can see what the lens sees) read all you can on
the subject (lighting, shutter speeds=why you have multiple shutter speeds,
f-stops, and why you use them and when, etc), and go shoot Horses in motion, standing about, waterfalls, fields, barns, houses, people, with flash and without. Become experienced with Adobe photo shop, and along the way,(this is the third part of three) you might find somebody like myself who doesn't mind the company, and may show you the "how it's done" hands on stuff, and off you go...
I love it, so much I retired completely from my 9-5 job 10 years ago.
Hey, pays for my Equine addiction! Just gotta try everything, and when you are good enough at it, find you niche...Remember, nothing good comes easy or quickly....Lw
