Several observations:
1) You don’t know what you don’t know. So trying to learn about the things you THINK you don’t know often misses important stuff that you were not even aware of. It helps to have external sources to tell you what you need to know about. (example: you can’t figure out why your shots either have blown highlights or black shadows. The missing information may be “dynamic range”.)
2) Ultimately, everyone learns on their own. Until YOU make the links between the information being presented (whether in a class, a tutorial, an on-line forum, a book, or in a mentoring session), and the results you’re getting, it’s all a bunch of blah-blah hooey. And that means that you have to try to apply what you’re learning until it starts to make sense, starts to click, starts to give you the results you’re going for.
3) Mastering the technical stuff doesn’t mean your photos will look good. Photography is a member of the visual arts, and the visual arts have a very rich history of accumulated knowledge, conventions, customs, and techniques. It’s all about the light. And the light reveals textures, tones, colours, surfaces. If light is yang, then shadow is ying, creating the stage for the light, working with the light to reveal and conceal. We are blessed by having many rich sources of information and insight surrounding us, but we need to take the time to stop and study, whether it is an art class, or a show in a museum, or a product photograph.
4) Timing is the difference between a joke that sparkles, and one that falls flat. Photography also relies on timing to capture the “peak” moment. But to capture the “moment” requires both anticipation and preparation, learning to see what is developing and anticipating the right moment to do the capture. Timing requires practice – lots of it. You can’t be fiddling with your camera controls when the “moment” happens.
5) Learning doesn’t happen until there is a link between conception and reflection: what was I trying to do, and how well did the results convey my intent? Learning requires the suspension of ego. Learning requires the deliberate acknowledgement of failure. Learning requires admission that you can do much, much better. It’s really hard to take a good picture when you’re busy patting yourself on the back.
6) Learning requires experimentation. Doing something the same way and expecting a different result is…. Well, you know. Learning requires getting out of the comfort zone. Learning requires making mistakes. Lots of them. Thankfully, with digital technology, these don’t cost you anything. Good experimentation requires a purpose, a methodology, and a way to analyze the results. Limit the number of variables, and concentrate on the key element or technique you’re trying to understand.
Of course, the more you know, the more you realize there is to learn.
