Those vajras are very good objects to exercise the process of focus-stacking in photoshop. Here´s another one
My dog Mabel and her friend Sam love to cuddle up together so they're usually 'stacked' in many creative configurations. Head on head, body on body... Here they're leg-stacked....
... the height is round about 15 mm

So, I went back into my friend's cellar at Avalon Vineyard in East Pennard with the thought to photo-stack N. murinus. There's a load of rotten, blackened wood underneath a massive mixing bin in the winery cellar, and the more interesting springtails seem to like it there.
With the Neelidae I've watched, they scamper for a bit, then pause for around a second before starting off again. Ideal for stacking, if you're quick enough... (taking different focused photos of the same, hopefully stationary object before merging them all with software on the computer- Zerene stacker in this case).
What it means, is that there's a good chance of picking out more detail as you can use a higher fstop, with less depth of field. I probably could have gone higher but then there's less of a chance to use the one shots on their own. It's a juggling act.
But, and it's a big but, you also have to be very accurate, lucky and get your different, hand-focused shots all done in under a second of an animal around 0.7mm big that's usually running away from you! In the pitch black of a cellar, with a torch. And this was at around x20 magnification....
As far as I know, this is the first time anyone has managed (or wanted!) to stack N. murinus! But I must say, I'm kind of chuffed with the results. Still not perfect, but it's a learning curve...
As an example of extreme stacking, here's a shot of Megalothorax minimus I took a few weeks ago, which would come up to the top of N. minimus's legs. At only 0.25mm big, again, no-one has been daft enough to attempt to stack one before, either, as far as I know.

A beach event was coming up and a stack of plastic chairs was sitting in the sun, waiting to be deployed...
The party rental place calls them “White Café Style Chairs, made for year round outdoor exposure. Plastic stacking chairs are great furniture at cafés, bistros, poolside dining and outdoor restaurants. Commercial grade plastic resin furniture is made to last with constant public use...”

Too cold and dark to go outside and shoot. So I stacked up the plates neatly and fired away. 2011YIP

Hills that make the Lickey Incline look like a molehill in your back garden...
13000 horses at the front and and the same at the back should sort it though, and trains of intermodal boxes actually aren't as heavy as you may think. Even so, these westbound boxes were down to around 10mph as they passed me, with rather more of the going up stuff to do.
Straight out of the camera this one, no ickery trickery processing...

Sea Stacks, Bandon Beach, Oregon.
This image was shot during the early morning hours. At this time, these sea stacks were perfectly lit up with an orange glow. The early morning sun was casting long shadows over the beach and the sky started to brighten up with a typical blue hue. I used a HDR image for the foreground that provided the realistic sharp image I was looking for. For the sky, I used a frame that was under exposed two stops. I composited these two images in normal blend mode in CS6. For a change, I did not overwork this image and I left it as real as I could. A lonely photographer (DW) gave a much needed scale to this image!

I have been promoting noise reduction by stacking for years, but while I was able to recommend "Starry Landscape Stacker" for MAC users, there was no easy to use Software for Windows.
This has changed lately, with the release of SEQUATOR, a very easy to use program for stacking untracked nightscapes (for noise reduction) and the best of all: It is freeware!
sites.google.com/site/sequatorglobal/home
So far, I have been using fitswork, a dedicated software for stacking tracked star images. While I learned to use it for untracked images as well, this process is painfully slow. It would therefore be immensely helpful if SEQUATOR was able to perform as beautifully as fitswork, without all the slow manual interventions needed…
Today, I was able to do my first test of SEQUATOR. To see how it performs, I did a side by side comparison with an image I already processed with fitswork.
First I had to find an untracked image sequence. I have been doing mainly tracked shots lately, but I found my Bisti Eggs image which I shot from a fixed tripod:
To get a meaningful comparison, I decided run SEQUATOR with the same preprocessed TIFFs I have used for stacking in fitswork and publish some 100% crops taken from the resulting TIFFs right out of SEQUATOR and fitswork and without further processing. SEQUATOR has several options for stacking, but I found that “Freeze Ground”, “Auto Brightness OFF” and “High Dynamic Range ON” worked best for me.
As you can see, SEQUATOR does an extremely nice job. There are no star trails and no stacking errors and I really like how the foreground and the horizon are razor sharp. Very impressive indeed!
On closer scrutiny, the SEQUATOR result has a tad more saturated colors than my fitswork resut, but selecting “High Dynamic Range ON” avoided burning the stars. The increased saturation leads to slightly increased color fringes around the brighter stars, but this would have happened with the fitswork image as well during post processing and there are techniques to reduce this effect during processing.
SEQUATOR is really easy to use and it took me less than 5 minutes to produce the result, while my normal workflow in fitswork takes about 3 hours to arrive at the same stage.
Conclusion:
I can highly recommend SEQUATOR! If I ever have to process an untracked image sequence again, I use SEQUATOR instead of my fitswork workflow.
On Windows, it is by far the easiest to use and fastest stacking software for nightscapes and produces very good results. Even beginners can immediately produce excellent results. There are no excuses anymore for noisy single shot nightsapes… ;-)
PS:
1. Of course I still highly recommend using a tracking mount to achieve “deeper” sky exposures, by using lower ISO and higher exposure times. This means that you have to shoot the foreground separately with your tracker off and merge the two exposures during post processing. For this techique SEQUATOR might not be the best software out there, but to stay fair, that is not what it was built for…
2. Here is a very nice quick tutorial for SEQUATOR. The only point where I disagree with Mike, is that for better sharpness and no burned highlights, I recommend to use HDR instead of Auto Brightness.
