Experiments In Afocal Microphotography

Excellent results!

Thanks. Still very much by accident--not even trial and error. I have spring break off and plan to spend some time being more scientific.

I'm trying to stick to the cloud as much as possible for this series of experiments. I'm using a Samsung Google Chromebook, and downloading the photos to the Chromebook via SD card. For photo editing I've been using the online version of Picasa, which is now incorporated into Google+. I'm looking at PicMonkey and Pixlr as well. There are some museum matting framing options in the desktop version of Picasa that I miss in the cloud version.

The result is superb!

I thanked you for your kind words, and then managed to delete the post while dealing with glitches. But thanks. Definitely an experiment in progress. But I have at least one student every day ask me how my experiments with my new toys are going. I might just be nurturing the first paleontologist that specializes in Martian formations and fossils.

"If you zoom all the way in you loose brightness and have a very small depth of field. So I rare xoom to more than 2.5 (the Olympus goes from .7x to 4.0x."

Just about the first thing I learned with this scope. I believe I'm going to have to use the lowest magnification possible to achieve the best pictures.

If you have a camera that will let you play with the amount of time the lens is open (shutter speed), this will take care of the light issue. The longer the lens is open, the less light you will need.

Just beautiful!

How cool would it be to display small fossils with their enlarged portraits (if one had the room).

My thought is a display that combines the actual fossils with a digital picture frame or tablet like and IPad running a slideshow of the pictures.

Very clever idea! You youngsters and your technology...

Hi Mike,

I really like your latest imagery. Bravo! I especially like the touch of the signature font and the mat and frame technique. I will definitely be stealing that in the future! :ninja:

Your idea of combining micro fossils with enlarged imagery into onw single wall disply is inspired! You should market them as I imagine they would sell quite nicely. I know I'd buy one!

Very nice :wub:

And I'm a teacher!!! But of course your native language is closer to Latin than mine. Thanks. I'll definitely have to fix that.

Don't worry Mike, french is a very difficult language, and most of french people have difficulties to write correctly our nice language. I wrote that to permit you to correct the name, just because someone could write it again like that ;)

Me too, I write mistakes, in english and in french (OK, not very often in french)... :rofl:

I recieved my Seben camera holder from Germany on Friday. 11 days to Canada not bad by regular post. No hassles at all or customs duty. Have not had chance to use it yet but was easy to figure out how to assemble and it is very sturdy, well designed. Does not feel cheap at all. Fit my three cameras with no problem

30X--same setup. Some washed and sieved matrix from the Atco member of the Austin Chalk Formation, collected from the TXI Quarry west of Midlothian, TX. Everything here is larger than 180 microns.

My next experiment is to try and deal with this the bits that passed through the US Standard 80 Sieve, smaller than 180 microns.

Not the best picture, but there are a lot of very small fossils in this mix. Some look just like ostracods. But others are rod shaped structures, or sharply tapered cones. I'll try to get better pics. A few examples are in the pic above. Thoughts?

The tiny little "cigarette butt" caught my eye. What the heck is it?

Looks like one of the pieces in Gardetto's snack mix. :)

Context is critical.

This matrix is known for being rich in teeth and bits of fish. But I'm trying to take it down to a smaller sieve. When I eyeball the sieved matrix I see black sand. When I put it under a scope I see an equal mix of phospatic nodules, some of which are teeth and broken teeth, other shark and fish bits. I see just as much white, silicate material, much of which looks to be forams, ostracods, and who knows what. A very small percentage is pyrite. An equally small percentage is tan, appear to be silicaceous, and almost all appears to be fossiliferous. The cigarette butt is an example. Bone, tooth fragment, who knows.

I'm working on better pics of the small bits.

I keep getting ahead of myself, trying to take pics of really small stuff. These pics of not so small stuff aren't bad. Harvester ant bed material from the Harpersville member--Wilson's Clay Pit, Brown County, TX. The ants tended to pick up material in the 1-3 mm. range.

I'm looking forward to seeing your pics. This little camera mount is an incredible tool in my opinion.
