Bog Rosemary
by Wayne Jones
I have not thought about flora photography for months. (I guess I am seasonally fickle until some snow- or ice-covered leaf, berry or bud catches my eye, and I have not been out that much this winter). BUT, recently I reprocessed this for a geographically-specific photo contest, so I thought I should post it.
I had a difficult time shooting this nearly five years ago. These flowers were hanging over an inaccessible shoreline where I was kayaking, and there was no way get close enough for my 150mm. macro, or even to set up a tripod. I ended up using my 100-400mm. lens plus 1.4X TC. As a result, two-thirds of the flowers were out of focus in all my shots. In more recent years, I have gotten better at manual focus-blending, so I went back to the archives and found that I saved most of the shots from the bursts that I fired trying to shoot these. I found three images shot during the same burst that went together well enough to focus blend, and came up with this.
Canon 20D;
Canon 100-400mm. + 1.4X TC (560mm.)

This is a phenomenal achievement - doing a focus stack HH at 506mm and on a kayak!!
Fabulous image.
Since I only shoot in the wild, and often end up where tripod use is not possible, I developed this technique out of necessity.
Manual focus-blending is really not that hard if you have a steady hand when shooting, so any motion results in just tiny closer/farther adjustments, rather than lateral or up/down. Since most of our cameras shoot 5 to 8 frames per second, it's often possible to find two almost identical images with slightly different planes of focus. Just selected, cut and paste the sharp parts for layers to superimpose over fuzzy parts.
EIRINI: Yes, the background was really that dark, at least compared to the subject. I shot in shutter priority with a negative 2-stop exposure compensation. As a result, I did not have to do any burning, blurring, etc. because the background was just very dark water in the shade, and it was a couple of feet behind the flowers. This "black water" it pretty typical for boggy environments (and it works great for reflections, too -- sort of like a black mirror). I am not a fan of artificial backgrounds, and I would actually prefer a bit of OOF greenery back there, but this worked out well for this image.
Cheers.
