Hello everybody. I have problems with the scan of a face. The surface is very bumpy. Short to the equipment:
Sony Nex 5n, cheaper Chromakey, softboxes for lighting.
I only use manual focus. The photos are so beautiful with 16 megapixels that I can recognize individual pores when zooming in. Lack of sharpness is not the problem. After shooting the pictures I increase the contrast and create masks in Photoscan.
In order to shorten the computing time for my tests, I work with only four photos, which is sufficient to calculate the front of the face. When I start aligning the photos, I only get ~ 600 tie points. In a test with a porcelain figurine, there are also 4 photos over 6000! How can this discrepancy come about? And why are the surfaces of the head so bumpy?
