Thanks for the clarification, Nick

The reason I asked whether it might be something trickier was that I couldn’t understand how you might successfully view a cross-eyed pair using any ordinary Stereoscope ... They are all inherently what I loosely call ‘parallel-viewing’ in that the eyes are not crossed.

However : Re-reading, more carefully, what you wrote to Sam ... I think all you were saying is that [like me, but unlike Sam] you free-view ‘parallel’

An easy to confirm this would be to print the two pairs of Raymond’s images that I posted, to a suitable scale, and view them with the Stereoscope ... then check that the effect is the same when you free-view them.

Likewise, you could do the same with Sam’s pair of the clock.

Forgive me if I am rambling

Now I'm confused. It seemed to me that Nick said he could see Sam's (cross-eyed) clock view instantly, but had to (of course) swap the images to see them in a stereoscope.

That suggested to me that Nick free-views cross-eyed naturally but needs the stereoscope for parallel viewing.

Me with stereo glasses on: cool

[ Very interesting topic but can't help feeling we ought to take a lot of this stuff to another thread out of respect for Raphael and others. ? ]

Yes, that was my original interpretation too

Regarding ‘respect’ ... Raphael has already stated that he considers it relevant

But I’m happy to ‘go with the flow’ if you want to start another thread.

Hi, let me try to clarify, Sam's clock I could see as is, but when viewed with my stereoscope, it was back-to-front. So I downloaded it on to my computer and swapped the images for each other and then viewed it through my stereoscope and it looked correct, I then viewed it freely and it still looked correct, therefore it seems I can free view Sam's clock both by cross eye and parallel. However Raymond's lab photo won't do that, I had to swap his photos to see it correctly with both free viewing and with my stereoscope. Now Sam's circuit board I can see correctly as is and with my stereoscope as is, I also downloaded that and swap the photos with each other and both free viewing that and viewing with my stereo scope produces a reverse image and the same thing happens to Raymond's white blood cell. So have I got some crossed messages in my head or what.

Regards Nick.

No problem veering from topic gents. I really don't mind in fact it would be great to see the branches of our discussion. That is just how it is. I say you guys continue discussion here as I'm following through and learning along the way. Discussion stems from our interest in macro-photography and with out the main topic it would not spring into existence. Let's carry on guys.

Got my PN-11 extension tube today. This is a 52.5mm extension. So my current set up is a Nikon Micro lens 105mm AF-D plus PN - 11 extension tube. Im still waiting for my PK-13 to add to the length.

So to play a short game. Can you guys identify exactly the following close up pictures. See if you can all guess it right. Labelled A to E.

Got also some stacked photo done. Magnification is way improved and I'm really happy with the results. I will test the limits of my set up once I added further extension tubes. I will run a test on reveres macro plus extension and see which one delivers better result. I also plan to do microscope objectives to try to reach ultra macro territory.

 

A. Details of the wing roots of the Crane fly. You can clearly see the second organ of flight. This helps with the flight sensory input.

I would guess they're from banknotes .... probably UK ones which I'm not very familiar with these days. B .... suggests Churchill to me and A ... the Queen?

The rest, I haven't a clue.

More detailed pictures. Photo Stacking really makes it "pop" and in full focus. These are very small flowers.

OK, Raphael, thanks.

In that case, following along from Sam's PCB pics (short baseline .... hypo-stereo) someone might want to try the opposite: long-baseline hyper-stereo. This is used for relatively distant objects (trees, buildings, mountains etc) where the two pics are taken many feet apart. (Needs to be a static subject, of course). I used to do a fair amount of this at one time and it can be a lot of fun.

Some nice examples here. Scroll down and pick parallel or cross-eyed (or indeed anaglyph) as appropriate

Raphael, those images are superb.

I'll mention a few points about the Novoflex bellows shortly.

This morning, I explored the CAD file-viewer’s rotation adjuster using the full clock file. It was pleasing to discover that not only could the image be rotated, but it could be set incrementally.

It took a couple of tests to determine what appeared to be the better ‘Z’- axis ‘increment’.

1° was insufficient while 10° was excessive, so I used 5°.

clock---stereo---left-right---5-degree-cross-eyed - cad.jpg

Having forgotten to set what is called ‘Environment Map’, the image doesn’t look as shiny as before. However, it instantly jumped to 3D when I went cross-eyed. There are still a few twitchy artefacts from the outlines, but overall it was a pleasing result.

For those that need to switch left for right, go to …

Bad photo of bee mites. Some things don't look so pretty in close up:

But closeup helps this fly on the flower

Great shots Jack.

Added a total of 80mm extension tubes on my 105 and tried 50mm reverse micro plus 80mm extension. Here are the results. These are so small that it is very difficult shots. Very surprise with the magnification and the reverse macro is amazing.

Hi Jack and Raphael, really good photos. Never realised that bees could get mites though.

Hi Michael, thanks for that, I quite like that one. I suppose really I've never thought about bees and such like having such things.

Regards Nick.
