Fly - stereo composite
Nothing special. Just the result of automating composition with a macro (the script-like variety) within Affinity photo.
It saves me continually getting the two stereo images the wrong way round. Yayy
7.5x Mitty @ 7.5x. FoV ~4.6mm wide.

When you swap the images, you invert the depth -- what was front becomes back and vice versa.Yawns wrote:Tried to do a couple of stereos (first time) .. just used Zerene default settings
Am I imagining things or ?... I have the feeling if I swap the image positions.. left to right and right to left I get a better "stereo" effect..
One of the orderings will be correct, meaning that depth from stereo is consistent with other depth cues from shadows and occlusion. That will look good.
The other ordering will be inverted, meaning that depth from stereo is not consistent with shadows and occlusion. That will look not so good.
In the very best case, a convex subject will invert to look concave, like the inside of a mask. Many people won't recognize this and end up concluding that the image looks 3D but somehow odd.
If there are overlaps, so that part of the subject is hidden behind another part, then inverted stereo will make it look like there's a slot or hole in the "front" part, though which you can see the entire "back" part. This looks so strange that most people will recognize it as clearly wrong, even though often they still won't be able to articulate exactly how it's wrong.
Zerene Stacker has no idea whether the two selected frames should be displayed left/right or right/left. Either way could be correct, depending on the optics, whether you stepped from back to front or front to back, what processing options you used, and whether you want your stereo to be parallel or cross-eyed. Ultimately it's up to the user to choose the correct order by visual inspection.

Re: It's always the fine print...
Far simpler than that I accidentally bumped it with the glue-bearing wire I stuck to the legs for mounting. Hence "nothing special". Silly mistake, but it seemed a shame not to make a stack from it anyway. The other side was damaged (as found).NikonUser wrote:Image spoilt by the haemolymph leaking from the pin hole (?) in the katepisternum

Very nice stereo image but your brain is very unforgiving when the left/right images do not quite 'add up'.
I assume stereo retouching has never been implemented in Zerene even though I think Rik has previously mentioned it.
StereoPhoto Maker (SPM) does have a feature for moving selected areas in depth on the other image, maybe that would work ?

There's no retouching from individual original source files. If you try, the operation won't be diagnosed as an error but the retouched pixels won't line up correctly.David Sykes wrote:I assume stereo retouching has never been implemented in Zerene even though I think Rik has previously mentioned it.
However, retouching does work properly when done from a Stack Selected output image that was generated with the same shift settings.
This can be an effective method of solving the "transparent foreground" problem, such as we see in Beatsy's pair where the legs overlap.
I don't understand. What problem is this addressing, and how might it be used here?StereoPhoto Maker (SPM) does have a feature for moving selected areas in depth on the other image, maybe that would work ?
