How to Fix 3D Scan "Blobiness" in postprocess?

ZBrush Usage Questions
#1

Hello, im playing around with photogrammetry, 3D scans, using agisoft photoscan for scanning various objects for 3D, mostly smaller objects (the size from size of shoe box to size of a chair, nothing bigger so far), but a lot of the scans suffer from blobiness, it doesnt look really realistic, i cannot show my work, but for example this is what i call “blobiness” random from net:

How to fix this IN POSTPROCESS, i have a lot of photos already and cannot take them again, so trying to play with depth of field etc. cannot be done, i know that the blobiness has a lot to do with depth of field (im shooting on tripod, F8-F11, 35-55mm Nikon D3200, default lense).

How to fix this when the photos are already taken? I tried to change in photoscan- Depth filtering from agressive to mild, and it helps but really only a BIT. Tried to go from medium dense point cloud detail generation to high, DIDNT help either.

The only thing that pops up in my mind is (how to fix ot at leats help it a little is: Is there some “sharpening” brush in sculpting sofrwares (zbrush)? Which will work like the opposite of “smooth” brush, that means it will “sharpen” the edges instead of smooting them? That might help… Im tired of the blobiness of the scans even when the scan comes out “good” its still blobby…

Is there such “sharpening” brush in zbrush? How to fight the mesh “blobiness” in postprocessing of the scan? (when photos are already taken)?

In your post you are talking about he problem of bobliness that I suppose mean softness but the pictures show a different problem related to spikes created by projection.
In any case about bobbliness in some point you need to relay in the diffuse map, convert it to normal map or displacement map and use it as normal map or to modify the geometry giving more sharpness with displacement or using the surface noise tool in Zbrush that can also apply it to the geometry.

In any case the photos that you use as example have enough detail and I think this process would work. But if the result is a lot softer that the one you are showing with the examples we are missing a level of detail because the software used or the quality of the photos. For example there is little chance that the 3d scan autodesk tool will give you anything else than softness but that is not the case of Photoscan Agisoft, that is sharper.
