OK, just middle-aged, but still. The weather was, once again, psychotic last weekend: approaching the 90s on Saturday. With gas prices slowly approaching what Europe already pays, and with a workshop coming up on the Palouse in eastern Washington, I've been practicing frugality and staying close to home...so it was back to Bellevue Botanical, this time with a tripod and with the new extension tubes.
Macro shooting is a whole different set of skills...I've shot close-ups using my 28-70L or my 70-200L, but that's nothing like using the tubes to cut the minimum focusing distance from two to three feet down to two to three inches...or closer. Actually, I wasn't that daring: of the 12-, 20, and 36mm tubes included in the Kenko set, I used only the 12mm with my 50mm f/1.8 II lens. That got me within five or six inches of my subjects.
The tripod and an angle finder become essential, at least for me. The DOF becomes very thin, so it's also important to ensure that the camera is as close to parallel with the focal plane of the subject as possible. In the posted image, the petals are fairly well in focus, but some of the flower's business in the middle are out...and the petal at the top is bending back just a bit, so it's pretty soft. I checked: the whole structure of that blossom was less than a quarter-inch thick.
Oh! About the whole "I grow old, I grow old..." line from The Lovesong of J. Alfred Prufrock: macro shooting is probably not for the bad of knee and vast of belly. Even with the big thunder gel knee pads, it was a painful b**** crouching and crawling and staying still while peering through the angle finder. In my landscape shooting, I try not to fall off of things; macro seems to be all about not falling into the subject! The quality and interest of the images, however, will certainly tempt me to clap on the kneepads again...but I'll try to remember to get the anti-inflammatories down my neck before I go.
