I have been using align chunks with cameras with success to preview alignments. However, I am having difficulty aligning chunks created from photos that I downsampled using Photoshop. The photos align well enough in individual chunks, but I can't get the chunks to align using camera positions. I have tried building "bridge" sections to tie chunks together better; the object is a long low building and the "bridge" extends its entire front, but no luck.
I have made no attempt to modify the settings of the downsampled photos, other than to note that they exist (though the dimensions are correct, some fields appear unaltered from the original). Could this be causing the problem? Like I said, I have built bridges using photos from two other chunks, but they will then not align. Downsampled from 5184x3456 to 3456x2304.
