I had shoulder surgery in late October and still in the recovery stage. I will be continuing to photograph micro mineral specimens. Knowing I would have a long recovery, I rebuilt my set to vertical and added 5 and 10X Mitutoyo M plan apo objectives. It is unlikely that I will be posting images here...

Those of us with wavellite may actually have the new mineral fluorwavellite. Paul Adams has been testing wavellite from a number of localities and has found that waveliite seems to scarce. He, along with Bill Wise and Tony Kampf were the authors of the recent article on the Silver Coin Mine. A frien...

I used to do mineral photography through my Meiji EMZ-5TR but was not satisfied with the image quality. I now use a Canon T2i on a bellows with finite objectives. There are some folks that take wonderful mineral photos using microscopes but they use high end ($35,000+ US) compound scopes. Even some ...

abpho, It is not that expensive, particularly for micros. There are a few of the ones from Mont Saint-Hilaire that are pricey but they are the ones that are very rare. I have been putting the Poudrette Quarry material together almost 30 years so the expense has been spread out. I also do field colle...

I very seldom post here. I primarily post at Mindat.org as I can upload bigger images. My typical upload there is at 1920 x 1280 at 2.5MB per picture. They allow up to 40MB per picture. The image is presented at a smaller size but you can scroll in with a mouse wheel to get to the full size. They al...

Thanks JL, glad you liked it. The Poudrette Quarry has been a favorite of mine for many years. I just wish I could have gotten back there to collect when it was open. I have 350+ specimens from there representing 217 species. It is the type locality for 66 minerals and I have about 30 of those. This...
