for one thing.

I went back to the original unscaled image , although 2 cuts, they are from
the same pic taken at the same time with the same illumination

The lower lead free de-soldered cap lead and the upper a control from an
older board. Proper silvery sheen, mostly, to the old one, brighter than the
background graph paper, and totally dusty light grey for the lead-free ,
tin-pest ? desoldered one.

Yes, I can see the matt finish of the lead-free one now. That's how they're
