Ruddy Darter Male
 
It was my second visit to the Decoy Heath nature reserve. After lunch I went to a different, much larger lake some distance from the first one.

I spent quite a long time with this individual, Sympetrum sanguineum, who was clearly patrolling his territory. He was in superb condition.

Shots of perching dragonflies usually have twiggy bits of dead wood or stems of emergent vegetation in the background. These tend to give moderate highlights in the image and various degrees of cropping are required to minimise these. I have done this with the single frames, the originals being present in the stereo pairs.

I was very pleased with the performance of the lens, careful use of the AF having been essential.

The stereos are crosseye.

Olympus EM-1 (aperture priority), Panasonic 100 - 400mm Leica DG Vario-Elmar at 400mm at 1/160 to 1/500 and f10 or f11.

The stereos, best viewed by leaning back a bit.

Another great series Harold. I haven't seen one as yet this year.

Thanks.

Thanks. I have, very rarely, seen one in our garden. The last one was rather worn, compared to this one, with the body bloom worn away. None this year, so far.

I am intrigued with your stereo images Harold. How were they taken and how does one view them? Not seen this before.

Thanks,

Steve

Superb shots Harold, I just wish I could make my eyes view the stereos properly. Try as I might they just wont work for me. I must just be wired up wrong! I haven't tried but would they work in my Owl stereo viewer if I printed them out?

I have covered this several times but, anyway:

Keeping the subject centre (or some other feature away from the edge of the frame) in the same position on the screen, two shots are taken, horizontally separated by what I judge to be the correct distance. (I work with viewing angles, which comes to the same thing but requires no measurement).

The images here are mounted for crosseye viewing, which works better than conventional on a monitor. So the one taken looking from the left side and the one from the right side are transposed.

You then have to view the pair with you left eye looking at the image on the right and vice versa. Some people find that easy, some find it impossible and some take many attempts. One you have mastered it it can work for life. An aid is to place you index finger vertically against your nose and watch it as you move it to the divider between the images, trying to be relaxed about it.

Good luck.

Harold

Thanks, Phill.

They would work in a Victorian stereo print viewer, if printed out.

Alternatively, have a few beers! *chr

Lovely images, Harold.

As you so rightly say, many dragonfly images are spoiled by complex & highlit backgrounds and, depending on individual preference, by limited depth of field (or, rather, by wrong choices on where to place the dof).

Using the various m4/3 long lenses with close focusing is really useful to get a good working distance from these skittish beauties.

Have you tried handheld focus stacking or bracketing for this type of subject? I took a load last year but, I'm ashamed to say, I haven't yet got round to processing them :rolleyes:

Re: DOF. I set the DOF preview on my EM-1 last year but have only just started using in in the past few weeks. A tip: don't set your focus distance while in preview.

Focus bracketing when the subject likely to move and/or the breeze moves the subject would be a good definition of a fool's errand. I can't do it anyway, as I can't be bothered to update the firmware.

I imagine it all happens during a burst, in which case, what are the chances of maintaining the framing?

Well, I've certainly seen some really nice images taken like that by others: I can't yet comment on insects, but I've had some OK results with flowers & unfurling leaves handheld in gentle breezes.

When I work my way through to those images I'll let people know *chr

Harold the Owl is pretty much a modern Victorian stereo viewer as far as I know so might just give them a try. I've also still got an old Weetabix 3D viewer that I had as a kid off the cereal packet in the 60s. Not quite Victorian but I just might try that too. It was that toy that first got me fascinated by stereo images.
I posted a link to your photos to a good friend of mine who is also interested in stereo images and he could see them in 3D and was very impressed. He said he'd give me some lessons :) failing that we'll go for the beer ;)
