Missourian Posted January 1, 2013 Author Share Posted January 1, 2013 Brittle star Dinwoody Formation, Triassic Block Mountain, Madison County, Montana It's hard to see in the 2D image, but the tiny black specks scattered across the surface are sitting in deep pits. They appear to be organisms that 'ate' into the calcite. I found this during Field Camp in 1998. Context is critical. Link to comment Share on other sites More sharing options...

Missourian Posted January 6, 2013 Author Share Posted January 6, 2013 More fusulinids.... Two 'pinwheels' Triticites sp. Plattsmouth Limestone, Pennsylvanian Leavenworth, Kansas These are preserved in chert and are cross-sectioned. The larger fusulinid is 2 mm across. 'Red beans and rice' Triticites sp. (irregularis?) Stoner Limestone, Pennsylvanian Clay County, Missouri The 'red beans' are actually lichen-like organisms that had grown on the weathered rock. The fusulinid in the center is 6 mm long.

I just tried using the camera my cell phone phone and got nothing really. I also tried using my camera without success. I'd think any phone camera would work. The trick is that you have to hold the camera steadily and precisely in the right position. Otherwise, everything goes black. Don't give up on it just yet. I haven't tried the DSLR yet.

Acryzona Posted January 8, 2013 Share Posted January 8, 2013 I didn't know that it was possible to take photos through a microscope with an Iphone. Those are very nice especially the Ozarkodina sp. and the ostracods. Too bad they went "right side" up, you could identify them. Do you use an attachment between the Iphone and scope, tripod, or just handheld? (sneaking off to get my wife's Iphone...)

Too bad they went "right side" up, you could identify them. I think many were "wrong side" up, but they were pretty well worn and rounded. Quote Do you use an attachment between the Iphone and scope, tripod, or just handheld? The steps I follow.... 1. If necessary, rotate the phone so that the subject is most likely to fit into the image field. 2. Fumble with the phone above the eyepiece until something shows up on the screen 3. Center the eyepiece view in the screen. This is the trickiest part. 4. Raise or lower phone until the image stabilizes. 5. Rotate the phone slightly until the field of view is centered in the screen. 6. Wiggle the phone a bit until the square indicator pops up (iPhone, at least). It usually sharpens into focus at that point. 7. If the fossil is bright, tap it on the screen. This will re-balance the lighting (again, iPhone). Otherwise, it will be washed out. 8. Snap the photo quickly. You can hold your hand steady for only so long. 9. Take many pictures. If you take only one, it won't be any good. I usually take 10+. I then bring them up on the PC, zoom in, and pick the sharpest one. 10. I always crop the image, but I seldom have to adjust the brightness. These steps can be cumbersome, but they become pretty easy with practice. Quote (sneaking off to get my wife's Iphone...) Seeing your avatar.... once you start, you may become addicted.

I was having a problem of details in white fossils being washed out as the camera tried to balance out the brightness levels. See the conodonts on black shale above. After a little research online, I found out that if you tap the bright subject on the screen, it will lower the overall brightness as desirable to some degree. An example: Context is critical.

Auspex Posted January 9, 2013 Share Posted January 9, 2013 It is a touch screen, and adjusts the white balance when tapped on an area that is 'washed out'.
