This is all very helpful information. I wish to thank everyone.
I am using a Samsung S20 ultra on a fixed base 15" high. Experimented with lighting and exposures, It took a while to learn but I now have raw 4000x3000 pics in native 4:3 mode that are pretty good. Even with four light sources, the PCB components still have shadows except in the center of the pic. They are too large to upload though.
I have also discovered that the lens does create a slight fish-eye distortion effect. Which I will also have to correct for.
Any ideas ?
So my new idea is divide the picture into quadrants to reduce the Fish-eye and shadows, Correct each quadrant tilt, skew,scale & fish eye then stitch the quadrants together.
It would give me more detail and less shadows. Any thoughts on whether this method is good /bad? Would I be doing this the hard way ?

Eventually I do need to plot their locations but actual measurements will be needed. I plan on overlaying a grid in a separate layer. I think actual measurements can be done in Solidworks. Still researching that.
My hope is to be able to measure parts and create accessories in CAD that fit on the Circuit board for my own use. Maybe a 3d model.
