Thanks Lou - I clocked that warning in the instructions. I tend to run in a very short range, never more than 30mm travel, and predominantly <10mm so fairly low risk. Having said that, I managed to get it confused so it ignored the "end point" and continued moving and taking pics a couple of times. ...

...How long does it take to process a picture like this, from start to end? For these images it wasn't too bad. I was using APS-C crop mode on the camera, shooting JPG instead of RAW and I set Zerene to 'pre scale' the images by 50% during stacking. So files sizes were pretty small. Overall, it was...

Bubbles

This unexpected "abstract" presented itself while I was tinkering with a micro aquarium containing a bit of pond weed - just some bubbles that were stuck to the glass. A single shot with a 10x mitty - cropped for composition.

Using Mitty M Plan APOs through a coverslip

Here's the first part of trying to do a less subjective test of the effect of an intervening cover slip on Mitty performance. I say "trying" because I appear to be cursed. When I use a 10x Mitty, or anything with lower magnification, nothing stirs outside my house except perhaps an occasional pedest...

Only shallow with the 50x - from coverslip inside surface to about 0.2mm deeper. I didn't take that test further due to limited FoV but will be testing further. I'll report back (in techniques section) when I've more comparison pics done.

Interesting. They are definitely of organic origin. But from which kind of organisms? Foraminifers? Corals? Echinoderms? Troels You were right with your first try - they're foraminifera. I forgot to mention - the images above were from a test of photographing through glass with a 10x mitty. I glued...

There's ordinary sand...

...which can be quite interesting in it's own way. Then there's star sand from Japan - definitely in a league of it's own. Both images to the same scale covering a FoV 3.5mm wide. Stacks of 120 and 150 images respectively, taken with a 10x mitty. http://www.photomacrography.net/forum/userpix/3490_no...

Sorry,didn't mean to keep anyone in suspenders. Forms were photographed separately then all loaded into separate layers, masked off and composited together in photoshop. Stack depths ranged from as few as 60 images and up to 180, guessing about 120 each on average. All these came from one small, spa...

Podocyrtis mitra (radiolarian)

Brightfield on the macro rig using 50x Mitty. I admit a touch of photoshoppery to add a subtle drop shadow and lift the form off the page a little. Apart from that, simply a 150 image stack, cropped and rotated for composition. Unsure about the ID, not my field, but I think it's right. Specimen is ~...

Love the hoverfly. Got the DoF just about spot on perfect for that one. Very nice composition and subject positioning too. Top notch.

Thanks for the positive feedback everyone - always nice to get. And thanks Lou for the memory jog by mentioning "microscope". I've been meaning to try a brightfield approach by mounting on a coverslip and lighting from behind with an LED flat panel. In fact... [short pause] ...just resumed typing af...
