Heck, yah! Those are awesome! Never thought about face polishing. Plenty more where that came from! Thanks for posting, Billy.

HOLY MOLLY! That Obsidian is crazy wild Jeremy!!! The first photo is called a double flow black... I love cutting that stuff and collecting it on our hounding trips... After the first cut of the rough, its easy to figure out the angles you want cut...A blast to work with.. The detail you put forth on these rocks are incredible...... I have two batches of Obsidian coming out of my tumblers soon, I hope.....Potential in all of them.. Again, two thumbs up!!! Looks like I better send you some "Gold Sheen" Obsidian, next time... Your great at capturing the material in its glory... Hey, Mike! Thanks for the kind words! That obsidian probably came from you! Good to know what it's called, so I can ask for more . Can't wait to see those batches!

It is likely that a geologist could tell you exactly what happened to create your obsidian curtains and other patterns. Those curtains or whatever they are called are stunning. Great job wrestling with the glare and getting such depth. Lol, stalking. I see this type clear sections, I believe it is in mahogany in many cases. Never looked at it with magnification. Time to start ! I'm curious about their formation, too. I'm sure someone here can shed a little light on the subject...... The glare is fairly easy to navigate, the microscopic bubbles that are the killer. I've got some really cool material that didn't photograph well, because of all the bubbles. There's no easy way, that I know of, to have mass removal of dust/bubbles in post processing. I think there's other types that have clear, but I don't know obsidian well enough to say. If you're curious, I made those photos public, so you can zoom in to them. You may need to wait a few seconds for them to clear up, they're pretty big files. Some sharper than others.

I'd never guess obsidian would look like that. Those pictures take the term "rock show" to a whole new level, keep 'em coming. Thank you, sir! Got more in the pipeline.

Hey, I probably stepped on some of those rocks! Hey I was leaving them for Jeremy for the pictures!! Hey, Henry! You probably did step on a few of these. Doesn't get much better than finding some beautiful rocks, with good friends!

That's amazing work right there the Mahogany Obsidian makes me see lakes of lava and creation happening. I do have to ask what camera/lens setup are you using? -s Thanks for the kind words! The Camera is a Canon 80D with 100mm f/2.8L Macro lens. The light box setup is described above. Pretty simple, but effective. I've also turned the photos on, in Flickr. You should now be able to click on the photo and it will take you to Flickr, where you can view the exif data.

I love you man! Dog gone it Jeremy looking super. I don't need another thing to do but what kind of camera are you using? Howdy, Billy! Thanks for the kind words! The Camera is a Canon 80D. It's pretty easy to use and you can find kits, with a couple lenses at Cosco.

Thanks, Dave! It definitely shows a different aspect to the material. Light box is definitely getting better and I think it's the way to go, for most individual Macro shots. Light Box is very simple. Cardboard box, cut out on 3 sides, with white fabric over the cutouts. You definitely want "Daylight" bulbs and would recommend LED's (they won't burn the fabric). There are many different options for backdrops (see some of Garage Rocker posts). I chose black, for the contrast. It seems to help when isolating your subject in post processing. If it makes you feel any better, I seriously struggle with the lighting. It's like an experiment with every new subject. The limited flexibility for lighting at downward angles, is the biggest problem with this setup. I'll keep working on it. Thanks Jeremy. The picture is helpful. What is in the upper right and left corners of the open side. I tried zooming in to look, but the photo is set to "private." What wattage LED bulbs did you use, and where did you get your fixtures? Did you fabricate the brackets? Sorry for all of the questions. Dave, those are redneck brackets, for an under cabinet light bar. I don't use it very much because the color is too cool and it throws off the balance inside the box. I've been using a 65 watt equivalent (650 lumens) indoor flood bulb in old Reptile lights. The fixtures are rednecked on L-brackets. Really high tech!

Did you buy an electron microscope ? Looks just like 3-D from one. Amazing structure in those rocks. Never knew obsidian was so complex. Great eye candy Jeremy. Still trying to wrap my brain around this one. Mahogany does have curtains of color, never thought they were so thin. A glass blower can start out with a small blob of glass with a thin coating of colored glass, as he blows the blob bigger the color layer gets very thin. Glass does crazy stuff in nature too apparently. Alright, James, I figured the obsidian would get your attention. I'm sure there are a ton of similarities with the glass you're playing around with. You'll know way more about it than I will ever know, but it sure is purdy to look at! No electron microscopes, just good glass (lens) and good lighting. I didn't know obsidian was that complex, either! Found out totally by accident. Made me pull out all my old obsidian to see what was hiding inside. Much of the interesting stuff was unfinished and is now in the tumbler. BTW, I love the glass that you're processing and tumbling! I've been Flickr Stalking you.....

txrockhunter - Awesome photos of some beautiful rocks. #3 looks like solidified & molten lava. Please share how you shoot your macros. I've had trouble getting the light just right (no major reflections) and no shadow from the camera. BTW, your avatar shows that you have 666 posts so far. Please don't go over to the dark side. We like you here. Lynn Thanks, Lynn! #3 is one of my favorite photos and was a total surprise. looking at the rock, you'd never guess that much structure was inside. I had no idea that there were other colors, like blues, greens, and yellows. I just posted my light box setup, above. The biggest factor is getting the focus plane of the rock, parallel to the lens. The lighting typically wants to be at a 45 degree, but curved surfaces really throw a wrench in the works. Having the opposing lights, illuminating through the fabric, spreads out the light for softer reflections. The obsidian is a little trickier, because you need more light inside, to illuminate the flows. Adjustable lighting comes in handy, to get in closer. Hope that helps a little...... I quickly made a post to get over the hump and closer to the 7's. Thanks for the heads up!!!

You and Garage Rocker have set a new standard for tumbled rock photography. These might be the best collection of macro shots I have seen. Really nice work. Chuck Thank you, Chuck! I guess it's like the Master and his Apprentice. Randy's a fantastic resource and is very willing to share his knowledge. To be thrown in that company is a great compliment!

Awesome!!!! Looking at those was like looking through an expensive coffee table book. Wow, Thanks! That's a huge compliment! Maybe there's room out there for a cheap coffee table book?

Jeremy txrockhunter , I'll use one of Scott's NRG expressions...Badass! The macro work is amazing with those rocks. It gives an entirely different aspect to the material. I've got no favorite, as they all look great. Nice work...it's great to see your light box is getting dialed in. Had we spoken about your setup? I'm still floundering with natural light sources. I can't wait to see what additional lighting set up you end up with. Thanks, Dave! It definitely shows a different aspect to the material. Light box is definitely getting better and I think it's the way to go, for most individual Macro shots. Light Box is very simple. Cardboard box, cut out on 3 sides, with white fabric over the cutouts. You definitely want "Daylight" bulbs and would recommend LED's (they won't burn the fabric).

Would love to see #7 and #8 even closer. Maybe 4-6x more magnification. It's the texture of the "velvet" I am curious about. Wow! jeannie Thanks, Jeannie! Funny thing about the rainbow obsidian, I think it looks better from a distance. At least the stuff that I have, anyway. I'll try to get a few closer ups and post them for you.

That very first picture is amazing. Then again, so are all the others. It’s like a whole other little microscopic world. My other favorite is 21. My other other favorite is 19. Of course that fossil is pretty cool too. It that a little fish or a snail type of thing? Thanks, Rob! It is a different world, and you don't really know what it's going look like until it's blown up. There's plenty that look better at face value and others that blow you away. Natures art, I guess..... That fossil is some sort of snail gastropod. Somebody smarter than me should be able to identify.

You killed it, Jeremy! Those are some sweet macros. The San Jacintos are perfect fodder for it. So many details. Love the fossil in #18, but they all deserve an ovation. Thanks, Randy! The San Jacintos do make great Macros. So much variety and color. I've said it before, but, thanks for the inspiration to get into photography! 2 great hobbies that can overlap.

Love the All-star batch! Great variety, polish, & as always, the presentation. No need to apologize for the quantity, as we all look forward to your photos! Gotta say 5, 7, 17, & 29 are the favorites. Glad you've thawed out enough to keep'em rolling. Thanks for the show. Jeremy Thanks, Jeremy! About time we see something coming from your tumbler, isn't it? I'm working on it. I've been playing around with some obsidian macros, but haven't been totally satisfied with the results. Work in progress.....
