I assume this angle will most likely be "from the top", such that it basically turns into a scanner, and then it's easier to do it with an actual scanner.

- myth_buster 12y agoA camera on a tripod and a light source would give infinite flexibility as to angle and illumination. Once optimized, the setup could be left as such.
- saganus 12y agoEdit: So maybe you do have better control, but what if the etchings are so small that there's no significant contrast change when viewing from different angles? I'm just basing my speculation on the fact that these guys probably have tried a lot of things and this is most likely the best way they've found. It would be interesting to hear from them what were the results of other setups.
