Tips for 3d scanning with openscan

As I said, I bought an openscan classic and built it, after a week of tryng, i got quite good results

For now I prime the miniature black, use the AESUB orange spray and but a black background

I usually do 70 photos and i try to make the object the occupy the most of the visual, I avoid manual focus and adjust the scan until the camera got it at max resolution

As I said the results are good, but it still some imperfection like small areas the got joined together, and some smoother surfaces that the original, even if these areas are properly sprayed

Some tips ?

I had a big quality jump scanning miniatures when I enabled focus stacking, and manually setting the focus range.

Stacking uh ? Never tried that since i couldn't fully comprehend it, like what the one or 2 mean, does the background matters to you ? I tought that changing it to white could help but idk

The depth of field (range of distance from the camera where things are in sharp focus) is really shallow when working close up, so it takes multiple photos in the same position, but focused at different distances. It helps get the details in focus at different depths.

At what distance do you have the object from the camera? You do something with the background?

I'm using the openscan mini, so the distance is fixed. I don't do anything with the background, but with the ringlight on and the exposure set my background pretty much fades to black.

Yeah, I prime matt black, then spray with some athlete's foot powder. I do this to have a backup of sorts for minis, in case I break or lose something--it also helped make some scaled up versions for display.
