Thanks Wishgranter and Foodman.

She just dyed her hair again so I guess that's why it couldn't be picked up. Stupid blondes!

I have been getting better results with high and ultra-high in the mesh settings. Unfortunately I'm using a laptop with 8GB of RAM, so I can't use too many photos or too high settings, as the application runs out of memory.

The project I am working on is an art installation so it doesn't matter if the mesh isn't totally perfect. In fact the errors in the mesh are part of what makes this fascinating. We have a series of 3D scanners at my University, but their results are shocking in comparison. Really having fun with this. Agisoft should make student licenses available.

I'm very interested to see how good the results can be from a single camera. I am just blown away with this software in general. Multicam would be really fun, but for now I am a poor student so one will have to do.

Thanks again. Will post further progress.

Hi Alexey

Here is a setup I used with roughly 18 camera positions. This time, as you can see, after camera align, it did not generate points on the hair. Why would this be? On previous attempts the hair was fine. I even underexposed so the blonde hair didn't get blown out on the highlights. Any ideas?

Around 18 - 24mm on a APS-C sensor, so 27 - 36 as a 35mm equivalent

Attached is a sample of my results. Thanks in advance!

Hi there,

Having some trouble getting any kind of decent results from my scans. I've read the manual and scanned the forum for tips, but I'm still not having much luck. My geometry generally ends up very messy.

I'm using a single camera, Nikon D90, 12MP, wide lens, f/8ish, 1/200. I've tried everywhere from 10 - 80 photos. Specifically, I'm trying to do a simple head scan, taking photos around a 180 degree ark. Here are some samples of the photos I've been using. I'm using the general align and mesh parameters put forth in the PDF tutorials.

I have seen some pretty good results from people scanning heads with a single camera, so I'm wondering why my results are so inferior!

Any general tips or advice would be greatly appreciated!
