Get all your questions answered about our latest Photosynth Technical Preview.
With the new synths being computed server-side, we have no log file on our side to help us track down which photos did not get synthed.
You might think that it is obvious, and perhaps it is for smaller synths.
When I uploaded my 'Wall' synths of both sides of my street on the first day it snowed here this year both sides came to between 321 and 345 photos so I was forced to break each side of the street into two walls.
When looking at the 200 photo wall, being told that 5 photos were not synthed is kind of maddening when it is not specified which 5 they are. It would help to be shown some thumbnails and a list of filenames so I can immediately go and look at where things are going wrong.
In my particular case, I do believe I know where some of the five are - namely where I was walking sideways down the sidewalk and some foliage obscured my view of the other side of the street for a moment, but I still don't know if all five rejected photos were from that segment.
If I understand correctly, then there is some photo assessment at after selection, before upload. I feel this is great and would like to see this improved in general. To me it is unclear how to delete a photo from the selection before upload.
There, I simply didn't have enough room to keep a single distance from the tree and keep the entire thing in view the way I wanted (would have had to walk through yards to capture it and you can see very clearly in the map view or global view where I ran up against the sidewalk on the other side of the street) so had to zoom out when I was forced to stand closer to the tree.
I went ahead and submitted all the photos that I had chosen anyway and 10 did end up being omitted, but that's fewer, I think, than what was suggested to omit prior to upload.
Mainly, I want a way, after the upload is complete, to pull up at least a list of filenames of the photos that didn't synth in.
Also, as to your question about deleting a photo from the selection before upload, if you tap or click a photo in the grid of photos on the photo selection screen during upload, it will darken and have a link on it with the word 'omit' and if clicked, it will be deleted from the selection of photos to upload.
I hasten to clarify that at that last part about omitting a photo from the selection to be uploaded, this is clearly before one moves on to the screen that asks us to choose which synth type we're submitting.
I'm sure you understood but my wording was a bit muddy.
Nate -- its going to be harder than you would expect to give you a great experience here because for privacy reasons we are not allowed to hang on to the filenames. (Filenames sometimes contain personally-identifying information, though I know that's rare, and it's a real pain to lose this info.) The best we can do is show you the thumbs that didn't make it. We do this most of the time (in the "i" panel). Is there an example you can point to where we're not doing this?
@PhotosynthTeam, thumbnail images are actually preferable to filenames, so that's fine.
I'd forgotten that the omitted photos count was a link.
That said, on a couple of synths, the listed number doesn't seem to correspond to the number of thumbnails displayed. Could you help me understand better?
This synth: http://photosynth.net/preview/view/e598ae40-a94e-45eb-a8b2-1bb801194a62 lists "3 omitted", but then displays six thumbnails under "not enough overlap"
This synth: http://photosynth.net/preview/view/b8544bbb-33b5-4dc0-ac4c-9fc2030210cf lists "5 omitted", but then displays four thumbnails under "unmatched images" and then three photos under "not enough overlap".
My first train wreck of an attempt to transcend the limits of a new synth (my attempt at a vertical + horizontal spin in one)
http://photosynth.net/preview/view/0a52f839-fef6-436e-a36f-4715b2aa7e79 lists "13 omitted" but then only lists three under "unmatched images"
OK -- been talking about this issue with the developers, and it seems like our design of how to communicate what happened to your synth and why you only see a reconstruction of 15 photos out of the 25 you uploaded needs some rethinking.
Question for the old-timers -- those who used the original Photosynth and tried to get things that were 100% synthy, or close to it: Did the 2D view help? In particular the fact that we laid the 2D view out in "connected components", showing the biggest one first? I'm considering bringing this idea back -- with the difference that in the new Photosynth only the biggest connected component would actually be visible in 3D -- the other photos would be there as thumbs, and you would have to look at the breaks between the sets to work out where you needed to add shots. Would that help?
2D View was extremely useful for intuiting what had matched together and what hadn't!
I actually asked about it earlier in the week: http://photosynth.net/discussion.aspx?cat=00581351-82d8-438d-a37b-7eadb3fb4991&dis=fdb1aaee-80ae-4c05-8f8c-db35f4f7f9db
I was happy with it in its original incarnation but if you guys wanted to push the typographic angle, a few simple category labels might not hurt for absolute clarity.
