The chunk info says that they are all aligned?  The order is weird. There seems to be two of each and they go up from 0 to 1 to 10 to number 19, then number 2

Hmm I did notice that the numbers were not in order in the cameras folder.. What could this be about? 

but now I understand how to edit masks later in Photoscan. It is still much easier in Photoshop.

I aligned the masked photos ...and came up with this the 2 sides of the building crossed in an x. any idea how to get them aligned correctly?

Darn, I just spent 2 days (off and on..and until midnight last night) masking 85 images of a building -with a lot of obstructions such as signs and cars as well as people in front of it. After trying to produce the mesh from these, I'm not sure that I'll have the stamina to try again with his new method. ...Which I still can't get my head around for now.... :'(

1. Align the photo, dense cloud and build the mesh without any masking
2. The generated mesh is roughly formed

3. Now, select the import mask -> from model! you can see the photos are masked with the rough model but not very fine

This is the part I am unclear about - in order to import masks, I need to have masked all the photos in advance. I though that this method was to avoid making detailed masks? Do you mean > mask the images, then import and build cloud and mesh without the masks first? And then import the detailed masks?

4. Then you can check the photo and edit the mask of each photo manually.

How do I edit masks once they are imported (and the mesh is already made)?

It what you are saying that I make masks roughly in Photoshop, then it is easier to adjust the masks more accurately in Photoscan?

What do you mean by: "Masking can be performed semi-automatically - at first you can generate masks from model and then adjust them manually."?

Thank you for all the help!

"the entire object doesn't need to be visible in the frame." That is good to know! So just part of it will work, as long as all of it is in some frames?

Oh well, back to the masking. I'll start over ...I had finished 20 out of 85 images (in 2 hours). Hopefully I'll be faster this time around.

here are 2 images (misspelled) before ...and after they were cropped and masked (saved as jpgs and downsized to 110 ppi  to upload here). Should I redo them without cropping?

Sorry I meant "masking", not "making". I did save the originals, so I'll hold off to get the answer (to whether not to crop) before masking and cropping the rest...

...I just read the instructions on the PDF and it says "Do not crop or geometrically transform the images". yikes. I guess I have to start over masking? The gate is quite small in some images since there were obsticals in the way, and it was especially small in the frame when the long wide gate was taken at the side view.

Yes they are cropped for the statue to fit as much as possible of the frame. Is cropping incorrect? I am in the middle of cropping and making 80 images of the Birkenau Gate. It has taken hours. (I hope I don' have to retrieve the originals...if I still have them, and start over.)

I used 49 images at 10 mega-pixels in raw format. The statue was high up so this is a close as I could get. I'm not sure what "I use 0.5 for reprojection error and 35 for reconstruction uncertainty". means? ......I just found it on the Help for the software...and I'll try an digest it later. Where do you find these settings? The Help guide doesn't say.

The higher the cloud density, the more bumpy the surface. Does anyone know why. Also, how would I improve the quality? I have uploaded 4 images. One is an image of the original sculpture (with white where the mask is). The second (that looks like porcelain) was form Catch 123, the second (less bumpy) was using high quality dense loud and the third using a ultra high cloud (very bumpy). I can't remember but I don' think I reused the map.
