Back to basics

You know that as an event shooter, I use TTL (through-the-lens flash metering, using a preflash) very widely. Much as it is sometimes hard to predict, it is the only thing you can use when things are moving quickly. Like at an event.

But sometimes, things go wrong. I had flash maslfunctions for part of Saturday’s shoots. You see, TTL is not really unpredictable -once you know how it works (metering bias to the focus point, for instance, and an assumption of 18% grey where it meters) it is predictable. So a malfunction is when it becomes actually unpredictable.

As it did Saturday with my dying 580EX II flash. Here’s three consecutive shots – I do everything the same, and yet I got, in rapid succession in the same setup, one dark shot, one light shot, and one OK shot:

Too dark. And the next one, way overexposed:

And the third one, almost OK:

I cannot live with this craziness. So then what do I do? I go back to basics. Actual basics. The basics we used in 1980. Namely, I set my flash to manual power setting (my camera, of course, is already on manual exposure settings).

One quarter flash power ought to do it, I thought, looking at where I was bouncing and what my settings were – and that worked great:

So then for the next dozen or two shots I stayed in the same place, shot people at the same distance, and kept the flash and camera set to the same. Bingo, predictable shots.

So when life hands you unpredictability, force predictability on it If you use the same settings and it’s all manual and your distance to the subject stays constant, the pictures will all be the same.

Sometimes, 1980-style basics work just great. Actually, they quite often do. My camera is very often on the “manual” exposure setting, for instance.
