General / Scanning small objects
« on: August 01, 2020, 08:39:20 PM »
I have two small objects about 5cm each, but I am unable to scan them properly..
I took dozens of pictures with a DSLR at F16 - 10 second exposures.
They are both plastic pieces that I would like to duplicate.
One is jet black and the other one is orange. Both somewhat shiny.
I overexposed the black one to get detail - and the photos do look good.
I tried putting them on a pedestal and walking around and taking photos.
Usually many of the photos were non aligned.
I also tried a rotating pedestal and the camera on a tripod, which is a lot easier, but I read that this was not recommended.
I also tried video - using ffmpeg to split it into a thousand images. Which mildly worked better.
What is the correct way to scan these &@*&$ things? My models are always crappy looking.
I even tried the mask method - to take pictures of the pedestal and marking them as masks.
Thanks! -t
