The biggest mistake I see new photographers make is they attempt to jump right into working on getting a business started. This includes; creating a catchy business name, logo, watermark, price lists, etcetera. This is often done before a new photographer understands the difference between aperture, ISO, shutter speed.
I certainly can understand the enthusiasm and admire it. That being said, don’t put the proverbial cart before the horse. Learn how to become a photographer before attempting to work on a photography business.
How do you know if you are jumping in too fast? If have to ask questions such as, “I have lens x and y. Which is the best for [insert situation here]”? You should be able to understand your gear and what each lens or piece of equipment is capable of doing under most circumstances. You should understand shutter speeds, depth of field, aperture enough to decide how to handle most situations. This doesn’t mean you need to be a master nor that you should never ask a question because we can encounter unique situations and problems.
I don’t want to discourage anyone from pursuing a dream. In fact, I want to urge you to pursue your dream and start a photography business. I would love to see those reading this to have a very lucrative photography business if that is your dream and wish. What I want to discourage, though, is to jump in too quickly which often leads to two things, failure due to financial losses and failure due to frustration and lost desire caused by not having enough skills.
