how to improve features? (project update)
This is an update on my behalf regarding my helmet project. I used baby powder shaken on my photographic subject and blew away the residu, making features this way. I made about 900 pictures in 5 loops in an amateur studio setting. Using two lamps and the subject placed in a white tent. I used a homemade rotating plateau, for 360 degrees imagery. Images came out ok, could always be better. Still some flash on the object surface. I run an alignment and got a large component, about 850 images or so. Not bad.
Because I was not very satisfied with the quality of the pictures, I decided to take some new another day. This time I tried outside in daylight in the white tent, but I cleared the baby powder of the subject so the original surface appeared. Smooth grey semi gloss single color. I took another 900 pictures en run RC alignment again. I got 45 components and my biggest one was 125.
could this really be the baby powder making features for better alignment?

I think this tutorial covers this topic very well, i'am am also interested into your results with and without powder.
http://www.3dscanstore.com/index.php?route=journal2/blog/post&journal_blog_post_id=19@Götz Do you now if RC has a "show your projects" board, or it's planed? I really would like to share my results in this forum, but the "General Discussion" board is not the right place for it, i think.

Tom, I thought you are a non-social-networker? Did I lose you to the crowd? :-)
Anyway, tingelbobber, afraid not - there is only what you can see.
We've suggested something like that ages ago but nothing happened.
I would just do it in General Discussion - there are quite a few lengthy threads where people were comparing results. So why not add yours?
I'm curious...

Another update today. I took new pictures again, in the same outside setting, white tent, rotating plateau etc. I sprayed baby powder on my object again an began taking pictures, creating 360 degrees photo loops from different angles and heights. I created 9 loops with the whole object visible and some closeup photos for details. I uploaded every loop individually in RC and got perfect alignments. 9 perfect loops, unfortunately I use the demo and can not merge components.
The only problem I got, was with the individual closeups, which were taken random on the details. These were the only photos which did not align properly. But I got to understand why! They were not taken in 360 loops. I took some new closeups, but this time in total 360 degrees loops, overseeing the detail. I created 5 closeup loops and again uploaded them individually in RC. Yet again all loops with perfect alignment!
Now for the challenge. I have uploaded all images (with all loops including closeup loops) with a total of 1783 images and I am running alignment at this moment. I will have to see the outcome of this, so fingers crossed.
