>>4048206I would only bother with actual classes for much more technical things like advanced retouching or studio lighting, and even then, there's so much out there for free. I used to teach beginner to intermediate classes, and +90% of the people there would end up being boomers that only shoot in full auto. The fact that you can at least shoot manual, even if you don't know exactly what you're doing, is a great start.
Stuff like metering is simple and universal enough that there's a ton of resources online.
The biggest thing is just being comfortable with all the camera operation, and being good at problem solving. You don't want to be stumbling around on a shoot because the lighting changed, or you have the wrong lens for the situation, or you pressed something on your camera and everything's messed up, or you don't know how to pose someone, etc. Being successful at it has much more to do with business acumen and interpersonal skills than actual photography.
