Sorry for my recent inactivity; I have been quite busy, but here is something very different from the rest of my stream. I have recently been experimenting with high magnification macro. This first one is a portrait of a fly found on my desk. Magnification: about 8X, 100 stacked images.

fucus stacking from 10 images
I need and use the Visoflex for wide angle down to 12mm

Negative Stacking
I used to do quite a bit of negative stacking in the enlarger in the 90s when I had my own darkroom and an enlarger that would take a 4X5 negative. I was gifted with an A4 LED light tablet for my birthday and decided to try a bit of negative stacking to see if I could reprise that technique in my repertoire.

Our Daily Challenge - Pile/Stack - 6/25/12
I finally found something that stayed still long enough for me to take several photos for a focus stack.
This is the first one I've tried with the mpe65 lens since I've had it.
It's 4 images taken at 2.5x and focus stacked using Zerene.
Not the best one you'll ever see, but hey, you gotta start somewhere :P

20 shots at 20 second interval each.
Open as layers in Photoshop via Bridge
convert to smart object
Layer average.
The result is similar to that achieved by very dark neutral density filter (i.e very long exposure resulting in blurred clouds)
actually my ND100 filter was useless because the clouds where traveling very slowly thus I could not get the effect I was looking for.
by using this technique I could get a result (almost) equivalenti to a 400 sec exposure. Impossible to get with a single ND100 filter.
Note to self: reduce time interval between shots to get smoother average

Stacking …. Many views may know what this term means but I’ll give my version so all will know. Stacked photos are more than one photo taken with a different focal point. In the case of this image there were 5 photos taken at different focus points. There are programs that will combine all the images using the sharpest points from all the images to combine one final image with the detail focused.
I’m glad from the last posting no one asked me what plant that was….. I don’t know, I was concentrating on capturing the images and not writing down the plant names. These were captured in the Colorado University greenhouses. I hope to get back again soon to correct some of my errors in shooting and further fine tune my stacking technique. This was taken with my new macro 70-180mm but not at the macro setting (1:1) I was probably about 1:4 ratio for this image.
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.

This group is also some of my first two attempts with 'focus stacking. A couple are random photos that I had two similar images of that I then stacked in the software (Helicon Focus). The rest are from a IACC (local photo club) workshop with light boxes and rock quartz slices that I did repeat images of (tripod used) with changes to the F-stop to change (or expand) the focus via DOF. I then processed the groups to see what additional focus depth might appear. The software also has a 3-D tool that I like but have not managed to duplicate for viewing so far. The double images are a snapshot of one small portion of the 3-D workflow. Does anyone have experience or suggestions with 'focus stacking' or 3-D modelling that might be helpful to me and others out there? The ‘focus stacking’ is especially helpful for those of us that are trying macro and close up photography. Thank you.

Found this cool little spot where tradition was too stack rocks i'm assuming.

Since Covid, I wondered what I could do around the house besides shooting birds. I decided to brush up on my Focus Stacking skills. This is a 40 image stack!
