Some actual stacks of mine (about time)

Post by Koorosh »

Hi everyone,
so to my knowledge I think I have only ever posted one stack on here. In part it is because I am not a huge fan of most of my work and I lack the finesse and beautiful level of skill that many members possess. The other reason is because I am disorganised :)

So here are 6 of my better stacks- only one of which I am personally proud of.
However, maybe the subject material may be less well known and interesting to you. I will leave my favourite until last.

I will start with this: it is a Eurytomid wasp, possibly of the genus Eurytoma but I'm not entirely certain. Numerous species are classical parasitoids where they lay their eggs in a host, with the larvae eating and eventually killing them. In this case however, I suspect that it is a seed 'parasitoid,' although in many cases it is unclear whether the larvae are eating the seeds or if they are eating another insect that has laid its eggs in the seeds already.
I shot this with a Nikon 4x BE objective with a Raynox DCR 150 on bellows, with a Sony a6000 and two janjso lights.

Image

Nothing to write home about in terms of artistry, not least because I am awful at using Photoshop, but it was also intended to be clear and concise. I also removed the other legs and antenna for that reason. The wings truncated as well, but look, pretty wasp!

The second is my first attempt at an ant image. This is Formica rufa, or a 'wood ant,' which is one of the larger, more robust species of ant in the British Isles, which is an otherwise depauperate place to be. I was walking through a heath on the way back from a collection day when amongst the many wood ants I noticed one of distinctly different colouration to the rest. My initial thought was that maybe there was some socially parasitic species I was unaware of, or a male perhaps? I took it home to find out. Turned out to be a queen, which was actually a surprise because of how peculiarly similar in size it was to a worker.

Colonies can reach pretty impressive sizes of over 10,000, and in Ants: Nature's Secret Power, the documentary claims that a single mature colony can prey on over 10 million arthropods in a single year.

I took 187 images with a 10x BE, stacked in Helicon with method C, with two Janjso lights. I can't quite remember if I used a 135mm lens to reduce the magnification or not. I think so, because this is a fairly large ant.

Image

Not the greatest, but it went down well on Facebook. I am picky about it, but I hope you like it anyway.

The third is another wasp (there is a theme here- my passion is Hymenoptera, and particularly parasitic wasps), which is an Ichneumonid by the name of Trychosis legator. Unfortunately I don't know much else about it, except that is one of over 2000 species in Britain alone. Indeed it is the most species rich family of all wasps, and potentially on the entire planet, with well over 70,000 species depending on which source you read!

It also has a fetching face. And an attractive backside as you will see :) I don't remember how many images this one had, but it was shot at full mag with the 10x and stacked with method C.

Image

I was very happy with the way the face turned out for this, in spite of the obvious cracking of the pigments in the eyes, but in this case I don't mind that- it's sort of aesthetically pleasing compared to other images where this happens. I've read of Decon 90 as a possible remedy, but have yet to try anything out.

Here is the ovipositor. Again I forget how many images it was, but I'm a big fan of method C and two Jansjso lights :)

Image

The next is a wasp from the Pteromalidae family. Again, this family is huge, and some authors think that the superfamily it belongs to would absolutely and easily have in the region of 1 million species. This is Lamptrotatus, from the subgenus Skleroceras (fusion of the final two segments to form the club of the antennae). Actually I will add another image of Lamprotatus splendens to give an idea of just how beautiful this genus is, but it isn't the most aesthetically pleasing stack.

Nikon 10x BE and Raynox, 112 images.

Image

Not happy with the out-of-focus part underneath, and I had to do some fairly heavy cloning work, but all in all it's OK. I would like to get a fresh specimen and get a really good stack with it.

This was an image I made at the Natural History Museum in London with their stacking kit last Summer. It was around 40 images with a Canon mpe 65 and a 700D.

Image

Finally, my favourite image so far is of another ant, Myrmica scarbinodis. A fairly unassuming genus generally, but I found them quite beautiful once I got them under a microscope, with their semi-translucent areas and deep ridges.

This was 191 images, with fairly minimal editing. I added a third light for the top of the head because I quite liked the look of cool blue contrasting with the warmer light from the Janjsos at the bottom of the head.

Image

I know this isn't a perfect shot, but it is as close to it as I have yet achieved.
Any help and comments would be greatly appreciated and I hope you like the set. Apologies for going over 6 images to the admins- I added the shot of splendens to show off its beauty :)

Hi Koorosh

I really like 2, 4, and 7. The last shot is mt favorite. LOVE the texture.
Keep up the good work.

I like these images very much. They are hugely helpful in understanding your interests and concerns.

These images look very good to me. No areas for technical improvement jump out. I have the feeling that you'll be your own harshest critic.

Yes, that's a good combination. Helicon's method C is the one that is like Zerene Stacker's PMax, which is top of the ZS menus to encourage people to try that first. Helicon had only methods A and B for a long time, in fact until several years after ZS came out and made PMax popular. I never understood why it took them so long to adopt the method, but of course I was happy that it did.

Thank you Rik and Mike :)

I got Helicon in the end simply because it runs so fast on my laptop, and retouching in Zerene on my laptop is relentlessly slow unfortunately. I am not a fan of how noisy the Helicon images come out though!

As for a lack of technical problems, I think you're being too kind! Thank you for the compliments. I will be composing images for a book on Encyrtid wasps of the British Isles, hopefully getting the time to do them in the Summer, but it will take a number of years before completion. I have done one already that I am semi- happy with, but I have had great trouble finding a fast way to make selections of the relevant body parts. I have stumbled across refine edge in photoshop, but have found that it didn't really work as well as I'd hoped. The last stack I did took in excess of 15 hours necause I had to manually rub everything out between hairs and so on.

I wonder if you might have any advice on a faster method of masking?

Best bet is to start a new thread specifically on that issue, showing what you started with, what you ended up with, and asking for assistance from the whole community. There are some master retouchers here.

Nice work, Koorosh. =D>

I keep coming back to look at your first image, the Eurytomid wasp. Whenever I have this reaction to an image, I ask myself, "Why do I find this so visually compelling?"

Part of the answer must lie in your choice to include only the extremities on the near side of the insect. You may have done this for convenience, but my sense is that it heightens communication. My eye is drawn to the dramatic "wasp waist." In my brain, the excluded extremities don't show up as "missing," but "behind the ones we see." To include them might be distracting.

Edit to add: Given your issues with retouching speed, have you considered slabbing? Your needs appear well-matched to the technique.

Thank you Chris :)

And yes, the image was very aesthetically unpleasant with the extra limbs in view, in part because one had an out of focus part where I stopped before the second set of wings started to make themselves visible through the first set. I removed them to make it clearer and less distracting overall, although someone had to remind me that I'd left the second antenna in- they looked good, but it didn't make sense to keep it in :)

I have tried slabbing once, but it actually didn't work how I imagined it to turn out. I also use Helicon now. Do I have to manually portion out slabs for that?

And Rik, I will definitely start a post on that. Would be great to find out some tricks :)
