Texture and additional lighting

Postby drndadoo » Wed Jun 17, 2015 12:48 pm

Hi all,
I made few test scans with SLS-2 + Turntable

Does anyone of you is using additional lighting to remove shadows or make additional scans for better texture?

It seems the problem is to merging textures to create the final texture by DLS.
here are some samples :

To avoid any shading you can try something like this:

For the colour temperature they mention 5600 Kelvin. And that's in the spectrum range of daylight (5500...6000K):

By the way: Some time ago I had also made tests with a circular LED illumination around the camera:
