I am trying to figure out how to reduce noise in scan surfaces. I have surfaces that are very smooth, yet the resulting scans show these areas with a mild roughness or noise.
In the cases where I have spray coated the objects, there are a few spray blobs but most of the surface is smooth, yet the resulting scans show the mild roughness or noise. In the resulting scans, the smooth areas are rougher and the blobs seem larger than they actually are.
Here are some images showing the problem:
In particular, on the soap label... the label is perfectly smooth with no roughness. Yet the scan shows a roughness in this area.
These scans are done in a pitch black room using both cameras and using a Custom preset which is basically the 'Quality' preset with a noise reduction of 2. (There are no artifacts seen in the camera views during these scans).
Is there anything further I can do to get these smooth areas perfectly smooth in the scans?

Sorry for the delayed reply.
Thanks for the ideas. I realize the fusing process will smooth out the surfaces. (The smoothing process will also smooth out sharp edges which I would like to keep sharp).
My point is... on a perfectly smooth surface, the scans show a slight roughness (noise). In other words... on a smooth surface, a slight roughness will be introduced.
On a surface which has been spray coated (in order to be seen by the scanner), the coating itself has a very slight roughness to it (and may have a few spray blobs too). In the resulting scans, this slightly rough coated area seems to become even rougher... which requires a higher level of smoothing which in turn produces a final mesh with either some roughness left in what are supposed to be smooth areas or a loss of sharp edges due to the smoothing required to make smooth areas smooth.
In any event, it seems this slight roughness(noise) in scans is unavoidable and normal.
