General / Re: Alignment problem with static tripod and turnable model

Although I have not tried this yet, I saw it demonstrated successfully.  The method is to shoot an image first without the rock in place.  Just shoot the background under the exact conditions but without the rock.  Then proceed shooting.  When you do your alignment, import that "blank" image as a mask.  You repeat this for ever "row" of shots.

Saves endless time.  I repeat though, I have not tried it myself.

General / Can someone explain what "UV Mapping Statistics mean?

Hello! I can't find this in the documentation. I am interesting in what the min scaling and max scaling mean. 

Thanks!!!

Fantastic.  So many great tips and knowledge from both of you.  I appreciate the thoroughness and thoughtfulness in your feedback.  It is interesting, as you mentioned, the surprises you can experience with the software.

I started another agisoft project with a different set of shots.  The results were amazing.

 I have determined that yes, I simply did not have enough coverage on the boulder.  A bit nerve wracking because I was shooting in a jungle with much sweat and sweat.  I'm glad my other projects are coming out well from the same location.

I do use a battery powered studio strobe bouncing off a large, diffuse reflector. This gives me a broad, even field of light and I am surprised that I don't get too much specular reflection off my subject matter.

Anyway, thanks again.

General / Photo Align unstable? Has the bug mentioned in the post been fixed?

I am really having trouble getting my photos (80 photos) to align consistently.  The problem I encounter is that the process reaches a certain point successfully, but then it just fails for the remainder of every image.  I have tried the "tie points" value adjustment and realign camera but to no avail.

As mentioned in other posts, if I (as a test), reopen my file and choose a selection of the photos that did not align previously and only choose that selection, the photos can align properly.  Ugh.

I feel my photo coverage is quite good on the boulder I am shooting. Lots of overlap.  There are some portions of the photos that are out of focus but I seem to cover those areas in subsequent shots where they are in focus. 

My image quality is at .75 or above for each photo.

If there is a method to alleviate this problem, it would be appreciated to have a step by step solve provided. Maybe my coverage is still not good enough?  And I am masking unwanted background in my photos.

Thanks,
