There's going to be a diverse range of photos here. I was wondering where to post it, but since insects, arthropods, and minerals are all works of nature, I would say it belongs here.

Here's a jumping spider! Spiders are plentiful in Kangaroo Land:

This one took me a long time. Original version is 350 MP, too bad flickr only allows maximum of 10,000 pixels in length.

This will maybe make you never want to eat another raspberry. I apologise in advance  ;)
I didn't mind, where's the berries you ask? Gone, I ate them.

Here's a short stack, an "Enhydro" in petroleum quartz. It's basically water trapped inside the crystals while it was forming. The water bubble moves around too!

A "grape chalcedony", some hotspots exist. This was when I first started stacking, and my lighting wasn't refined, unlike now.

Heulandite on Apophyllite Crystals in Half Vug. Always love these types of crystals, they look like landscapes!

Here's one of my recent ones with refined lighting. These are some blue fluorite a Chinese crystal seller gave me, I placed the order on my birthday. It's lacking some depth, I need to work on composition as well.

Hope you all enjoyed! Any suggestions and criticism is welcomed!  :)

Beautiful images ... and I have my own Laowa 2.5-5x Lens on Pre-Order :D

Hope it ships soon ... and thanks for your effort in making us all aware of it!

It's my pleasure! Always great to see gems coming out of China, as much of these there is:

My day was truly ruined by that.  >:(

Also Laowa might even make one that goes into higher magnifications. We'll see! There's also some other great things being planned for dslrs, although they have been feeding mirrorless recently! I cannot disclose any information as of now  ;)

Impressive macros!
My only comment (not meant to be a criticism) is of the spider shots - you have a zone of sharpness, then the foreground and background goes abruptly out of focus. I understand why it is like that - the sharp zone is covered by the stack and the rest goes out of focus very quickly due to the shallow DOF. But it looks a bit weird, as if the spider has stepped out of patch of fog, you don't have the gentle roll-off from the plane of sharpness into the foreground and background you normally get. I wonder if there is a way around this?

Is it possible to decrease the interval of distance* gradually to 'soften' the transition?

But it looks a bit weird, as if the spider has stepped out of patch of fog, you don't have the gentle roll-off from the plane of sharpness into the foreground and background you normally get.

I am not MC, but the extraordinarily-shallow DOF is an intrinsic part to high-magnification stacks. The higher the magnification, the more abruptly the focus 'ends' when you stop stacking. The lower the magnification, the smoother the transition. (Nothing can be done to change this ... and some macro shooters like the "stepping out of the fog" look :) )

Conversely, wide-angle landscape shots (the inverse of high-mag macro shots), "everything" is in-focus with just one click.



I wonder if there is a way around this?

Yes, do deeper stacks.

With live subjects, however, that's easier said than done ...

Try taking 140 shots of a live jumping spider on a warm day ... impossible ... which is why most high-mag arthropod stackers typically use dead subjects ... or forget stacking and use flash-photography + small aperture, if shooting live arthropods.

Personally, I always found it out of the question to kill tiny wildlife just to photograph it, which is why I only photograph/stack living arthropods (not the dead shells of them).
(I have no problem photographing something I found dead, but no real interest in doing so, either.)

I accept the fact stacking tiny live subjects raises the bar in difficulty ... like the difference between hitting a Nolan Ryan fastball ... and hitting a baseball placed on a T (T-Ball) ... but it also make the end result more gratifying, if you can get it right.

But to each his own. There are some incredibly-detailed "dead insect shots" out there, but intently photographing dead subjects was never my cup of tea.

Yes, with a dead subject, small increments + an enormous amount of stacks eventually creates an "everything in focus" result ... but, again, that's not so easy to accomplish on a live, active, position-changing arthropod (in studio) ... even tougher to do outside, with air movement.

Sorry I got it wrong way round and I think you mis understood me...

I meant to gradually increase the movement of the camera towards the subject with the last few exposures; that would soften the transition from totally in focus to totally out of focus.  If done exponentially it wouldn't mean many more exposures, it could start *towards* the end of the already sharp zone, if using a focus stacking machine then it should be programmable?

With welding it's called slope out.  The welder gradually reduces the Amps and the power of the welder fades to zero at the end of the weld to produce a nice finish to the end of the weld.

That's definitely the best website for these types of stuff!

Ahh yes, I understand what you're talking about. One way around it would be to simply take more exposures so that bit of blurred odd-looking foreground is in focus. Content-aware fill should also take care of it with ease since I have no way to replicate the settings as of now. I found that weird and was thinking of cropping it out too.

Great results.  Show more when you have them.
Sure thing! :)

Yeah, the approach to live things would be drastically different. Everything in my stacks are dead and preserved as specimens. I try to buy them most of the time, but sometimes I have to make my own. I know a local seller where the money he makes goes towards breeding and infrastructure of the rural area he's in. Pretty good specimens at great prices.

Yeah, the approach to live things would be drastically different.

The approach for live specimens can be three-fold: 1) time of day, early morning for larger subjects for still air and decreased mobility; 2) in-studio, taking a sample of the environment to create a natural'istic' image; 3) selection of species, i.e., those less likely to move about. [One of the reasons I stack crab spiders, and other 'sit-and-wait' arthropods: they 'hold still' for stacks :)]


Everything in my stacks are dead and preserved as specimens.

As is the practice of most stackers. You fooled me: I thought the jumper was alive.

I know folks who borrow stock from entomological displays. Generally, they have a working relationship with the curator: "you provide me with bugs, I will take great images of them for you" :)


I try to buy them most of the time, but sometimes I have to make my own.

Have to?

Personally, I question the 'obligation' to kill wildlife to photograph it. For example, it wouldn't go over well if bird photographers began to kill avian wildlife as a hobby, so they could prop the bird corpses up, to spend hours taking intricate photos of the feathers. I realize it is more 'acceptable' for the mainstream that some photographers do this with arthropods, but (conceptually) to me it is tantamount to the same thing.


I know a local seller where the money he makes goes towards breeding and infrastructure of the rural area he's in. Pretty good specimens at great prices.

A dubious enterprise, IMO. But to each is own.

I do intimately realize the difficulty in taking photos of arthropods, and the desire to make them 'hold still.'
[Hence my targeting "ambush predators" (or camouflaged prey), for stacks, which have a tendency to hold-still by nature. With active arthropods, rather than stack, I use a flash with small aperture.]

My preference is live "in-situ" nature photography, but often, I have to collect them with a sweep net and attempt to create a natural'istic' image (esp. for tiny specimens), but I return the arthropod to the area where I found it when I'm finished.

Personally, I could be persuaded to take stacks of dead specimens "for science," but not for pleasure. I'd have to check myself. My own view is a desire for an arbitrary photograph of an animal should not be more important than that animal's right to life.

For me, my entire joy in nature photography is to capture an animal I chance upon, in its environment, without disturbing its sanctity. Sweeping for bugs is a deviation from this, I realize this too, which is why I keep it to a minimum. But I'm okay with it, as long as I take the animal back to where I found it. It's a compromise that I am okay with, but we all have our own parameters. Anyway, sorry for the digression ... and thanks again for the photos and tip on the lens ;D

Nice mineral photos.  I like the spider also. 

Responding to Roland's comment about the abrupt transition from pin-sharp to hazy focus:  One suggestion from extreme-macro.co.uk is to use an iris diaphragm in the optical path to extend depth-of-field and soften (by diffraction) the first and last few shots in the stacking sequence:

http://extreme-macro.co.uk/m42-iris/

This describes a set-up with an iris inserted between a microscope objective and a tube lens.  With a dedicated macro lens, simply stopping down to f/22, f/32 or f/45 should work similarly, I think.  Lighting or shutter speed or ISO has to be adjusted to compensate, of course.
