About classes, that's entirely up to you. BUT every payed photographer I've talked to said classes are a waste of time and money. If you ever get to the level of photography where money is involved, agencies will be more interested in your photo portfolio rather than what degrees you may or may not have.
Admittedly I'm biased. I teach a class at commercial photography school, and I teach privately. Two different beasts, entirely.
I also know many professional photographers, some of whom took classes - and were happy too - and teach as well.
I've observed a few things.
A) For some people, it doesn't matter whether they take a year's workth of classes, or self-learn, they're never going to become a pro photographer. It's not just whether they can take a picture or not, it's also a mindset.
B) Some people start the classes, and it's obvious they don't need them. They were born to be photographers. In 20 years of teaching (only part-time) I've had two. One dropped out of school rather quickly. Made it in NY. It was the correct decision for him.
The other one decided to stick it out in school, but on his own terms.... didn't care about the marks, but recognized he had access to equipment he wouldn't have otherwise, and access to an amazing wealth of experience in the faculty. I was fortunate, in that I teach a creative left-right brain type course (rather than straight technical skills). We wanted to be challenged, and I gave him challenges to meet. He would bring me the most amazing PJ images you have ever seen. I would bring a several decades worth of experience looking at and taking photos. We both knew the marks were perfunctory and that he was going to pass. What he wanted to do was to pick my brain. I think the entire faculty did this too. We knew we couldn't "teach" him the same was as the others, so we let him pick our brains.
C) These are the competent photographers. The unheralded blue collar shooters that don't write popular blogs, or get written up in magazines. They just slog along, making living at doing something they love. Two bills away from needing to find regular employment. These students, I believe, benefit from classes. It gets them up the learning curve very quickly so that they can start earning much sooner, and helps them to avoid the most common mistakes. As someone mentioned earlier, a photographer
is their brand. If you screw up early, it's hard to re-establish that brand.
I think the other thing a photo school can teach people is the business of photography. It's tough enough trying to get the shot right. At least with some classes under your belt you're not being distracted trying to figure out the invoicing/bill-paying/tax-collecting/tax-remitting/insurance/pricing/client-info-management/etc side as well. A small-business course, tailored for photographers, is probably the most important courses a photo school can teach.
imho, of course, and ymmv....
