Any image manipulation other than typical stacking procedure?

Hi,
As little as possible, but as much as necessary
The last one a little more, because of the reflections

The last one look liked a "created" image via computer interpolation rather than actual photo. No doubt artifacts of the software used to touch it up.

Hi,
I see that you don't like the last photo and it even bothers you.
I don't want to upset anyone here with my pictures, so I have just removed it.
Sorry, but I've only been on the forum for two weeks and don't know the preferences of the users yet.
Best, ADi

ADi, please dont delete anything... I like to to see (other peoples!) stacking artefacts.
The only thing that bothers me is that your images are jolly nearly an order of magnitude sharper than mine
(This doesnt honestly-speaking bother me as I really enjoy stacking and the view that I get at the end).
It might be fun to see a side by side (cross-eyed) 3D view of, say, the little house spider?

I would like to give pleasure with my photos, but not to upset anyone
I can 3D only in red/cyan e.g. radiolarians.

especially for me because I can not cross my eyes

To see the stereo in side by side images the level of eye-crossing required is not much different to reading a book or looking at the screen of a mobile phone, 8 or 10 inches from your nose.
(it is not the bonkers eye-crossing of the school playground).

Hold your mobile phone underneath the image and slowly bring it towards your face whilst still looking at the phone. Every so often divert your gaze gently at the computer screen behind the phone.... At some point the two images will form three images... and the middle image will be the stereo one (with the red dot closest to you, and the yellow dot furthest away).
One confusing problem is that you have to have/get your head level so that the circles overlay properly.
I do understand that it is not possible for some.
I have just had a go with this image and on my monitor, which is about two feet wide; the third middle image occurs when my mobile phone is 10 inches in front of my nose. when I am sitting about 2' from the screen.
The further you are from the computer screen the less converging you need

I hadnt thought about this before, but the closer the centres of the two images, the less ones eyes need to converge; so the half-sized pair below might be easier:

No nO it does not bother me rather I am interested in your techniques and the photos are awesome. Just questioning the differences in appearance.
