Greetings all, Now that we have a stationary camera on our new trinocuar stereo microscope, I tried some focus stacks, something I had never been able to do on fossils before! (I do it at work for geological specimens) I used Picolay - a free ware that works very well right out of the gate. you can get it here: http://www.picolay.de/ So here are some initial results. First, a tall spired gastropod that is about 2mm in size. I had 6 levels of focus from background to tip of the spire. First a single normal shot like I wold have had to settle for in the
Fred posted a topic in Fossil PhotographyI had some fun yesterday combining fossil whitening techniques with focus stacking. I hope the result is interesting enough to share. I sure learned a whole lot by going through this process, and it was great fun too! So here is the story. The specimen is a Diademaproetus praecursor from the Foum Zguid region (Morocco) I prepped a couple of years ago. I applied an ammonium chloride coating, after which I shot a series of 22 pictures using a DSLR with 150mm macro lens at f13. The focus point was changed manually over the series of pictures.

Just wanted to share my first attempt at focus stacking. These crinoid fossils were found in Sandoval County, NM. The larger fossil on the right measures 12mm in diameter. To get this shot I used my Canon 6D with a 100mm 2.8L macro lens and a tripod. I placed the fossils on a piece of black acrylic (outside) and took a series of 6 photos, each with a slightly different focus area, then I combined the photos in photoshop. Each photo was 1/50 sec, f11, ISO 400, no flash. Any feedback is welcome. -Zach Size reference:
