Hi Wishgranter,
I guess my problem in thinking about it results from a different project - the complex abbey choir ruin.
There I have about 750 images and the alignment took the whole night.
It resulted in one component all right but has some falsely aligned areas (or groups of cameras) which resulted in two surfaces in a short distance from each other.
Firstly it was quite a challenge to figure out which cameras are affected (but manageable thanks to the handy inspection feature). And then I am not sure what will happen with the CPs or rather when to stop with them since I will always have some images or cameras where my CPs will not cover the whole are but only say half.
Anyway, I will try out some more and am looking forward to the tutorial.
