I combined six different captures of these tiny water drops caught in a spider’s web to capture the range of light coming from behind the leaves that the web rested on. The effect reminds me of a Gustav Klimt painting.

Exposure data: 200mm f/4 macro lens, 66mm of combined extension tubes, six combined exposures at shutter speeds from 2 seconds to 15 seconds duration, f/32 and ISO 100, tripod mounted.

Variegated Gladiolas, photo by Harold Davis. View this image larger.

There’s a lovely clump of variegated gladolias in the garden. Partly shaded by a climbing rose, water drops cling to them in the early morning. A single drop reflects the world of these flowers.

I used my 200mm f/4 macro lens, a 36mm extension tube, and a +4 close-up filter. I exposed at ISO 200 for 1/4 of a second at f/36.

Papaver Drops, photo by Harold Davis. View this image larger.

In the garden, water drops hang from a poppy bud, swinging at the end of its stem. Reflected in the drops, the flowers themselves are upright. You can see the poppies in the drops on the stem itself, as well.

Both photos are tripod mounted. I used my 200mm f/4 macro lens, 36mm extension tube, and a +4 close-up filter.

In other words, these are very, very close, and magnified several times life size.

I stopped down for maximum depth-of-field at f/32. Using a setting of ISO 200, I exposed the top image at 1/60 of second and the bottom at 1/80 of second. While I was exposing for the bright water drops and not the darker background, I still intentionally underexposed so I could get a faster shutter speed, and so the bright areas wouldn’t “blow out.”

The gentle rain turned to dappled sunshine, and I went out to photograph water drops in the garden. The drops shown here are decorating a tiny Hardenbergia, or Happy Wanderer, with a deep red Camellia flower in the bokeh in the background.

I offer this rose in the hope that the new year is prosperous and happy for us all, and on behalf of our new beginning, Katie Rose.

Drop City, photo by Harold Davis.

Close up, the water drops gathered on the petal of the Rio Samba Rose remind me of a city, or civilization, all huddled together on the side of a flower cliff.

Rosa ‘Rio Samba’, photo by Harold Davis. View this image larger.

It rained over night. In the first light of the morning sun, I photographed the translucent petals of this Rose (Rosa ‘Rio Samba’), lush and drooping from the weight of the water.

Day Lily in Morning Dew, photo by Harold Davis. View this image larger.

In the early morning, in a shady nook in my garden, I found this day lily in the morning dew.

At the close macro range of this photo, it’s hard to get all the flower in focus even with the lens fully stopped down. So I combined six different captures in Photoshop. Each capture had a different point of focus.

I’ve dubbed this technique HFR. You can read more about the technique, and see other examples, in High Focal Range (HFR), Red Flowering Dogwood Blossom, and Gaillardia x grandiflora. Overall, if done right, you can use this technique to get a subtle three dimensional effect, but not so 3-D that it is disturbing in the way those 3-D spectacles in the movies were.

Caught in the Freesia Drops, photo by Harold Davis. View this image larger.

After a night of gentle rain I went out into the garden on a bright, overcast windless morning. The patterns in these water drops on the freesias caught my attention (by the way, the shape reflected in the drops is a leucospermum flower).

Wet Leaf, photo by Harold Davis. View this image larger.

I saw this small leaf with water drops in our side yard and couldn’t resist taking the time to photograph it.

I’ve written about using noise for aesthetic purposes. I’ve also explored the possibility that noise generated by boosting a camera’s sensitivity (ISO) will become a historical artifact and thing of the past. I’ve also explained my strategies for effective noise post processing.

It’s time to take a look at a technical challenge that decreased noise generation at higher ISOs solves.

The other day I went down the block to photograph apple and cherry blossoms close-up on a sun-drenched but windy afternoon following days of rain. The challenge here is that for these extreme macros I almost always want as much depth as I can get so that reflections in water drops and the surface of the blossom all are in focus. At ISO 100, my typical setting for quality work, this implies a long shutter speed even on a bright day. Shutter speeds longer than a second just don’t work when there is a breeze!

If I could get acceptable results in terms of noise, boosting the ISO would seem to be the solution. At higher ISOs it would seem to be easy to get the shutter speed up from the 5-10 second range to something like 1/25 of second. At 1/25 of a second, I would need the Gods of timing with me, but I could wait for a still moment and have a decent chance.

I think noise isn’t a detrimental issue in these photos, so boosting the ISO for maximum depth of field at faster shutter speeds works to make these technically “impossible” photos possible.

You can judge for yourself from these results. All were taken using my Nikon D300, tripod mounted, with my 200mm f/4 macro lens and a 36mm extension tube. The lens was stopped down as far as possible (with slight variations in recorded aperture, as noted), so the only significant exposure differences between the photos were ISO, shutter speed (and, on the other side of the exposure equation, the amount of available light at the time of the photo because natural light does not stay constant in the late afternoon).

For comparison, here’s a ringer, shot conventionally at ISO 100 and 6 seconds and f/45. The blossom was relatively steady despite the wind because of its position relative to the tree trunk. This was my last shot of the series as the sun set. I like the soft quality of the blossom in the sunset light, but you’d be hard put to say that the noise characteristics are significantly better than its high ISO bethren.

As sunshine came through the rain clouds I photographed this water drop on our peony bush. There’s nothing like a water drop formed by rain and lit by sunshine for creating a whole minature world of color.

Hanging On, photo by Harold Davis. View this image larger.

In a sunny intermission between squalls of rain I photographed this rain drop hanging onto a climbing geranium blossom. Even fully stopped down, in the sunlight the exposure was only for a fraction of a second, and the next second the drop had fallen down and was gone. As I dismantled my equipment, a passerby asked if I was photographing a groundhog (yesterday was Groundhog Day!).

“No,” I replied, “just a water drop.”

“Well, at least they can’t see their own shadow.”

Or, maybe water drops do see shadows in their short lives.

In the beautiful morning sun of a crisp new morning after all the rain, I photographed these water drops on a leaf using nested extension tubes.
