Or just print a section of the photo big on your printer and use a protractor.

Windows Violation simply means that some parts of the stereo view protrude forward of the stereo window. Purists tend use the term a bit pejoratively maintaining that it shouldn't be allowed.

I don't think it hurts occasionally - it can work quite well on some shots - but it can be overdone. It happened by accident on this one because of a rushed cropping job on the originals and doesn't work particularly well.

t was a stock-in-trade with old 3D movies and gained a (deservedly) bad reputation.

Found this while browsing through some old (personal) pics. Parallel viewing (complete with window "violation" )

Incredible things, Arduinos. You can even make a Wireless Tin-Can Telephone.

Huh?

I was going to post this link in the current macro thread but I didn't want to regurgitate this conversation in that thread. So ....

**LINK**

If it helps, here's a picture of the original Q plus a close-up of the large sprocket area (which clearly shows the skip-tooth profile):

sdp-si sell roller-chain sprockets if you can find something suitable.

There was also an article about that kit in MEW-106 (May-June 2005).

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

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.

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:

[ 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. ? ]

Super kewl Raymond !

SIRDS .... I'd forgotten about those. I could always drop straight in (parallel viewing again). I just tried some on a web site and find i still can (drop straight in) so all is not lost after all.

[ Years ago, my sister could always see them easily but her husband could not however hard he tried. He always swore that we were putting him on - that the whole thing was a huge joke at his expense. He got quite grumpy about it. Then one day he saw it. The look on his face was unbelievable! ]

No problem Michael !

Ah, but I wasn't. As noted, I download the original image and flipped the pair before parallel-viewing.

I'd heard that before, Neil and the values I'd used were an attempt to avoid some unknown 3rd party software rescanning/resizing my (carefully prepared ) pics. Particularly in the upward direction where pixels have to be invented.

Seems I'm failing.

I could resize to 10 x 7.5 x 120 or perhaps 8 x 6 x 150 but would I be wasting my time .... would they be "processed" anyway?

(And to answer the obvious question .... no I'm not really that bothered anyway. It's mostly a theoretical exercise. Time is hanging heav(il)y

No way I could ever do cross-eyed (nor much of wall-eyed these days) so I copied the image, flipped the views and looked at them with glasses.

Interesting that the feature near the edge at the 1 -2 o'clock position looks like a hole. I think it's just the colouration ... light on one side and dark on the other that gives it a similar appearance to a side-lit crater.

Or maybe it's just me

... or NASA Live carries it

Red (L)-Blue(R) anaglyph is one way. I think most stereo3D-philes would prefer either

- side-by-side postings in:

(a) cross-eyed mode - right image on left; left image on right, or

(b) wall-eyed (parallel-eyed) mode - left image on left right image on right

or

- simply post the individual image and let the user do his/her favourite thing.

Raphael,

Just a word of appreciation for starting this thread. It has been really, really interesting !
