Jerry, are you hand-holding these stacked images, using a tripod w/macro rails or something like automated like StackShot? In a controlled environment I used a geared head and macro rails but in the field I only handhold so far...thanks for any input...JerrySF
Jerry, I use a sturdy tripod, and a remote release for stability. Since I usually focus at 10x magnification in live-view, the mirror is locked up anyway. I focus at the closest point, gradually working toward the back of the bloom - by eye more than anything else. I've only been doing this stacking stuff for a week, so I'm still working things out. The biggest hazard so far is gentle breezes that I can't even see until I have high magnification; even my breath and body movements stir up enough air to move the flower...
One thing I plan to change is aperture size; I normally shoot at f/11 to maximize DOF, but I'd get a creamier background with larger apertures. This means that the focus points will be more critical, with thinner slices in sharp focus, but I'll see how this goes - I may be able to go out tomorrow morning.
I've never gotten around to getting a rail system, though I've wanted one for a while. The "StackShot" I just heard of the other night when I downloaded the Helicon Focus software. I'm going to work on method for a bit before I invest in more equipment.
I like the results so far - I've long been a bit frustrated with my macro floral work because I've had to include the blurry parts of some really tiny wildflowers as part of the "artistic" aspect, when I'd sometimes like the whole bloom sharply rendered, front to back. It's nice to have the choice, at least...
