Percussive learning

Percussive learning in a world of automation is what it says in the subtitle to this blog. What that means is me making mistakes. My old boss used to say “if you think you’re good, you’re not comparing yourself with the right people”. In my case, I think the right people have me well outnumbered. It’s been very humbling to find that stuff I have just learned is well-known to everyone else. So this blog is not instructional – I have no secrets to impart. Where I witter about something technical, try it yourself before assuming I’m right.

Slightly uneven development, perhaps?

But one thing I have learned is that it’s ok to make mistakes. And if you accept that you will make them and that being wrong doesn’t mean you’re stupid, then you get to learn. Learning means thinking about your mistake and working out why you didn’t get what you wanted. Or maybe looking at a picture and asking yourself why you are less than delighted. What would have made it better? Then think about how to do more of that.

This means reflection. It means saying honestly to yourself “I wish this was more…” and then working out what more means. If the definition of madness is repeating something and expecting a different outcome, then reflection is the road to sanity. The aim of reflection is to not repeat the same mistakes. Many of them will be similar, but what you are hoping for is to break things differently each time. Or if not break things, then to hone in on that thing in the picture you want to do more of.

I’d like to introduce you here to another idea – that of reducing variability. Anyone involved in manufacturing will know this inside-out (see above for me being outnumbered). Every process has a natural level of variation. What the manufacturing people strive to do is understand what this natual level is and then reduce it as far as possible. Then, if the output moves outside the expected range, you know that something is wrong.

What I have learned in photography is that my methods need to be precise, so that I can understand why something went wrong or be able to repeat something that went right. Mostly this means consistent exposure and development. I always use a light meter for example. Then, by looking at my results, I learn to understand and use the light meter better. I have been a bit of a tart for different developers in the past but I’m over it now. When I started out I developed just about everything in Aculux. These days it’s Rodinal for its keeping qualities. Like the metering, I always use a thermometer to get my chemicals to the right temperature and I use the same method of development and agitation every time (unless I am deliberately using stand development). So the results are that the negatives should be correctly exposed and consistently developed. Any variations that show up were either a deliberate choice or a mistake.

Anyway – that’s the theory: reduce variability so that it’s easier to understand what happened when the unexpected occurs. And then keep trying new things to see what happens. Break things with deliberate care.
