I hadn't tried Shutter priority before; "they" say it's for long exposures with a tripod, or on the other end of the scale, for sports and other fast action photos. And I rarely have opportunity for either.
But how about in macro photography, where the tiny subjects are almost too fast for my shutter finger? For the last few days, I've been experimenting with the fastest shutter speed setting my camera can handle. And I'm happy! I managed to "freeze" some amphipods!

|Tail end of an amphipod. Their legs stick out in all directions, which makes sense, seeing how they move about; they swim or scramble forward, backward, or sideways, "upside-down" in our terms, or right-side up; it makes no difference to them.|

These photos are almost as they came from the camera, except for resizing and adjusting the white balance. I took out a few scratches on the glass, as well.
I had to jack up the ISO to 800, so there's a bit of noise in the darker areas, what with shooting through old glass and moving water. But the colours are truer than at my usual settings, and the flash doesn't produce the awkward highlights that show up at slower speeds. And even a running hermit crab gets his photo taken!
