The following specimen is one of several pieces I did, and I don't think I ever posted a photo of it, so you won't have to look at the horrible original image. |

I agree, re-photographing your mineral specimens is sometimes a great thing. You know I did this several times and presented the results here. Carles did the same. And I liked these 2.0 photo sessions for two reasons: I could see my progress in photographing minerals and (sometimes) I got photos that did the specimens justice. So I can encourage you, Michael. Do some more reviews of specimens (if you have the time and the mood for it) and show these photos here. I think Carles and I are not the ony ones who would appreciate it :-)
Best regards
Tobi

Tobi,
Besides the benefits you mentioned, I have had the pleasure of seeing and holding several specimens that I haven't seen in quite a while, years actually). So, yes, I have started reviewing many of the early photos and re-doing some of them.
The preceding photo shows a piece I found in a box that had never been photographed and hadn't even been catalogued yet. Today's post features a specimen that I photographed yesterday. It can keep your wonderful Mt. Xuebaoding scheelite company :>) I acquired this piece 28 years ago, and Carles is right, specimens from this locality are getting harder and harder to find. So, congratulations on acquiring a fine scheelite.

Nice to hear that you got into reviewing! And sure, "meeting" some specimens again after years is without a doubt another reason to start a new photo session :-)

Very nice beryl, lovely little piece from that wonderful locality. And thanks again for your appreciation of my new scheelite. A nice beryl/aqua from Xuebaoding like yours is also something I would like to have in my collection. I once had one but sold it because it didn't meet my criteria anymore. I'm glad for you that you could get one some time ago when prices were not as insane as today. Your beryl deserves a place outside the box! ;-)
