I think I would consider myself an advanced amateur – very solid in some types of photography, woefully lacking in others, and kinda ok on a few more. Photography is like any skill which requires eye-hand coordination, and some thinking through of what you’re trying to achieve. I’ve made up a list of sorts of stuff I don’t do very well and need to practice. In my case, it’s portrait lighting, studio lighting, capturing the moment during action, controlling DOF in macros, macro lighting again, working with flash modifiers… and so on.
For each topic, I try to find references, sample photos that illustrate the concepts, and other information that may help me figure out a systematic approach to that topic. Then I try to set up a series of shots to explore the topic and get a feel for which variables affect the image. After this, I upload the series into the computer and review each one both from a technical and esthetic point of view. How well did I get the exposure? Where’s my focus point, and is the DOF appropriate? What does the histogram look like? How’s the composition ? etc.
After a careful scrutiny of the images, I’d do a second round of shots on the same topic, now incorporating the critique I just did above. Again, upload and scrutinize. If I’m starting to “get” it, there’s an improvement from the early series to the later one. In any case, I’ll take notes about what I think I need to work on more, or where I just don’t get something. That gets added to the list.
I have posted before the results on such experiments, one on portrait lighting, another on macro lighting.
I’m also a member of a photography club, and we try to meet at least once a week to critique each others’ photos, get pointers from the more experienced members, and generally help each other figure out things that we want to know more about.
The other reality for me is that I have very little time available to do this stuff, as I have parental responsibilities (both for my kids and for my senior parents), business demands that pop up outside of “regular office hours”, volunteer committee obligations, fitness sessions, and extended family tasks. So, some weeks, I might get in a night of shooting, others I may not get a chance for days. Eh, life is.
