focus stacking – Orion's Cold Fire

A Focus Stack in Need of Some Work

My idea was that this cantaloupe would make a good substitute for one of those really weird looking moons of Jupiter. But I need to get the exposure right and then I’ll need to practice cutting it out of the background with photo shop. Then if I can superimpose the Enterprise next to it in front of a starry field, I can drag in Shatner. “We have to rendezvous with the Vulcans on Cantaloupus IV or millions of people will …. DIE!”

As noted earlier I had a touch of cabin fever so I decided to try my first outdoor focus stack. What this means is that I have to drag along a laptop computer and a tethering line in addition to the camera and tripod. All of this is easy enough. What isn’t easy is telling the wind to stop blowing for the requisite two or three minutes of exposure time. And in fact, this picture is cropped as tightly as it is because some leaves were blowing around in the debris pile. Looking at it now I also note that the left side shoot is a little over exposed. So let us say as art it’s slightly underwhelming. But as an experiment in field macrophotography technique it will be “required reading at the Academy.”

Name That Tooth – The Answer

“There agelong she had dwelt, an evil thing in spider-form, … and she served none but herself, drinking the blood of Elves and Men, bloated and grown fat with endless brooding on her feasts, weaving webs of shadow; for all living things were her food, and her vomit darkness. … But none could rival her, Shelob the Great, last child of Ungoliant to trouble the unhappy world.”

I can’t stump you folks.

I’ve got to say, this photo stacking has amazing capability. The detail is impressive and the stitching is imperceptible. I tried stacking jpegs and then raw files. I thought the composite made from raw files looked very slightly better but it took an hour and a half to process. That’s more than double the jpeg time.

Here’s a wildlife shot to guess at. Whose tooth is this? A tiger? A saber-tooth tiger? A rattlesnake? A vampire bat? A regular vampire? A dinosaur? That creepy monster from Alien? Take a guess.

Focus Stack – Dried Flower

When is a dried flower better than live spider? When you’re doing a focus stack. When the subject doesn’t move it comes out a lot better.

The first three photos are three of the 136 photos that I stacked together. Notice depth of focus in each only comprises a small fraction of the total image.
