Re: Show your faces!

I'll guess I'll join the old farts parade. Here I am with the wife and kids (out of view) enjoying the solar eclipse in Riverton, Wyoming back in August, 2017. Taken on a P/S about 30 minutes before totality.

Re: Wulfenite on Mimetite

Usually the mimetite from Rowley is more yellow rather than the orange in your image, and the highlights off of the wulfenite crystals seem a bit too reddish to me. Getting accurate color balance with a black background can be tricky sometimes. A quick auto color correction in PS resulted in a much ...

Re: Trippy colored landscape (the solution revealed!)

Rick - very interesting but the stuff of nightmares for me :shock: After being without power for 5 days last week, apparently our water heater thermostats failed and caused the pressure relief valve to open after the power came back on, dumping hot then cold water into our basement. 200 gallons of b...

Re: Forum upgrade completed

Looks great Rik, thanks for all the hard work. So far no problems or issues (except remembering my two-letter user name in order to log in, 'senior moment' I suppose)

Welcome to the world of mineral photography! Almost all natural diamonds, and natural crystals in general, show growth features on what may nominally appear to be smooth surfaces - it is up to us macrophotographers to show the wonder of these types of crystal imperfections. Diamond testers only work...

Another great feature, but, my friendly admins now keep me from downloading software. Rik, is there a way to side-load the updates?

Form it into a loop with handle, and use the looped end as a holder to burn stuff in a flame

Stick it in hydrogen peroxide (must be clean) and make some H2 and O2 bubbles - may be a slow reaction, though

stepped Magnetite

Had these images for a while, though I would share. Interesting morphology for magnetite. The greyish material is tremolite. First image with Canon 50D, MP-E 65 and is a stack (1 cm FOV), ZS D-map, the others are single shots using a Canon 35-80 with the front element removed to get about 1x on sens...

Overstacking

Now that I am actually using an automated stacking rail (WeMacro), its tempting to make the step size smaller than it should be. We all know the issues of too large a step size, which leads to banding of unfocused areas. Is there a down side to making step sizes much too small (i.e. 40 micron should...

Bertrandite with new setup

I replaced my Beseler enlarger stand which I was using for hand stacking via a 3-axis micrometer stage (kids actually wanted to do some darkroom work) with a custom built camera stand, allowing for any angle shooting from vertical to horizontal, fully adjustable in three directions, and made from pe...

So we went to IKEA yesterday supposedly just for some Swedish meatballs. A Jansjo was on display in the upstairs showroom, but none for sale. Did get two of the new NÄVLINGE, in black, with the weighted round base. Have not tested them yet for photography - they seem brighter, more uniform, and inde...

Really cool image. Reminds me of the poem by Augustus De Morgan: Big fleas have little fleas upon their backs to bite 'em, And little fleas have lesser fleas, and so, ad infinitum. And the great fleas, themselves, in turn, have greater fleas to go on; While these again have greater still, and greate...

JANSJÖ no more!!!

My JANSJÖ LED lamps from IKEA have finally bit the dust, and they are longer sold at our local IKEA (eastern US). Instead, they have been replaced by the nearly identical NÄVLINGE series - reported to have a color temperature of 2700K according to the IKEA website, the same as the now discontinued J...
