I was wanting to re-shoot some chips I had shot years back and am finding that some of them have this crackle appearance.
Is this "normal" - e.g. that just happens, or is there some better way to store these things to keep them from degrading? In most instances these are CPUs where you can pop / peel the lid off, so no chemicals were used to decap. Here is a representative example. This has been exposed to air for 5 years or so.
