Subtle details are often revealed when I take the time to look closely. That’s when you need that “critical focus.” It also helps to have multiple shots. There’s always a blurred image – (as with any group picture, there’s always someone with their eyes closed). Fine hairs? See the hibiscus. I credit a darn good lens. And water is always tricky. Close-ups don’t give you a lot of depth of field. Sometimes nature conspires. The steady rain wilted my newly bloomed lily. I got some nice water. Colleen says my eye sight is failing. At least the camera lens compensates for other shortcomings.
