It's as if someone else, someone who actually knew what they were doing, took over my hands that afternoon!

If I did anything to get myself in the zone, it was just a day of driving around in the desert summer and taking pictures. The location was pretty good, but no better than plenty of others; I didn't meditate or fast or anything like that; on everything else I shot that day I had a good but not exceptional "hit" rate.

I know nobody's figured out how to summon up the magic on cue, but how do you "gently encourage" this kind of visit from the Consistency Fairy?

That's Zen photography. Put some on the gallery.
