Sad excuse for a photography shop. Most shots made at 1/8 to 1/13 second exposure f/9 to f/13, manual mode, incandescent white balance. Old Nikon D70 with good Nikkor f2.8-4 set on macro setting. Moldy camera with broken auto focus. Rested end of lens on Uncle Ben's long grain rice box to hold steady for slow shutter speeds. So the poor photos.

Great pics and tumbles Jim!!! Moldy old man and moldy old camera do great work!!! About molds and mosses Bill: " A rolling stone gathers no moss" "This proverb refers to what is well known about mosses and lichens - that they are slow-growing organisms that don't thrive on disturbance. A sure way to prevent a colony of moss from growing on a stone is to move it about. As with all proverbs, it isn't the literal meaning that conveys the sense but the metaphor."

Nice sampling, just the tip of the iceberg? That's a heck of a turnaround time.

Nice sampling, just the tip of the iceberg? That's a heck of a turnaround time. Lot of variety on the Rio. Been there done that place before. This time rocks were carefully selected with tumbling in mind. Size, shape, solid, smooth, lack of patina, lack of divots. As ready to tumble as possible. It is a tumbler's paradise. A lot of the bigger slab size rocks have been taken. Tons of high grade tumble size rocks just waiting be collected. Many small high grade agate/jasper/chert biscuits that could be center tapped with a hammer to 3-4 pie cut shapes. Easy fodder for the tumbler. Wished I had taken photos of the tumble size pebble shore lines at higher fixed lake levels. Collecting rate about one 1"-2" pebble per 3 seconds. Fill your buckets. The wood you about have to saw. So get bigger pieces. It breaks jagged with a hammer. Messy

These are outstanding, James. I'm always looking for photography tips and I appreciate you listing out what you did to get the photos ... including the rice box! HA. Were some of these collected on that huge trip you took a while back? The one with the really loooong thread?

Were some of these collected on that huge trip you took a while back? The one with the really loooong thread? Paul All of them from that trip Paul. Ran out of all decent rocks, had to go get more. The lighting system is pretty raw. Man, light is everything. Fair camera skills helps, but not the quality photos Randy Chuck Rob Jeremy others put up. Must say, tumble photos greatly improved in the past few years. And they are macros and shiny and dark and not flat and demand a skill. If you can photograph round shiny dark small objects up close you need a pat on the back. Most other photo settings easier X10. Digital cameras makes it a lot easier.

James, you are a tumbling master and you have the stones to prove it Not everyone ones to add grit daily. Good thing my barrels open real easy. #1 desirable feature in those PVC barrels with the easy to remove rubber caps.

Maybe I can secure permission from a ranch that would allow a bunch of people to go. I would like to sit back and watch a group of collectors attack lol. Funner than finding the finest. They would all pick up the pretty rocks when in reality the finest rocks often have drab patinas.

The purple brecciated jaspers are very similar to Sci Fi (Porcelain) jasper. Probably rolled off the slopes of Chihuahua Province of Mexico. Hard jasper that takes a great tumble polish. It comes in so many sexy patterns, even swings into conglomerate(see related Confetti jasper). Mexican agates woods and jaspers brought to the US without the dangers of collecting in Mexico. Any volcanic slope draining into the Rio may have been a contributor. Looking into Mexico and over the Rio Grande, note butte like mountain to the left of the more rounded mountain. Looks like Woodward Ranch peak. Looks like many peaks in Big Bend of west Texas. Agate machines. That's the source for so many Rio agates. That peak may be in the province of Coahuila, Mexico. Wish to be dropped over there, and be pulled out quick if problems arise ha.

Purple jasper everywhere. Some very showy. These OK. Probably hematite makes the color.
