Rocks, Little bit closer I
As a Petrologist (rock expert), I study rocks and minerals under the microscope and have the chance to see the other side of the natural beauty of rocks and minerals which has been unknown to most people. Along with studying the properties of rock forming minerals under the microscope, I also start to look the samples from artistic point of view and would like to use the word “Micro Art” for my works. This definition is presented by Michael Brown (a great macro photographer with great vision for capturing the nature’s beauty), he chose “Macro Art in Nature” as a title for his macrographs and since I used microscope to capture the hidden beauty laid inside of rocks, I use the word Micro instead of Macro. I don’t want to go through the scientific details of micrography using polarizing microscope but to give the general overview; I would like to present some basics. In rock microphotography with microscope, the subject is a thin section of rock sample with maximum thickness of 25 micron which is fixed on small piece of glass. The thin section lies between a complex combination of lenses and filters and the aperture only controls the amount of light which passes through the sample. See the schematic drawing and you will find too many differences between macrography using macro lenses and micrography using microscope. I will give you more details on micrography and polarizing microscope later, for now just enjoy the picture.
به عنوان يك پترولوژيست (كسي كه با سنگ سروكله مي‌زند) مطالعه سنگها و كانيها در زير ميكروسكوپ بخشي از كار من رو تشكيل ميده و اين شانس رو به من ميده كه زيباييهاي سنگها و كانيها را يك جور ديگري ببينم، زيباييهايي كه براي اغلب مردم ناشناخته است. در كنار كار تخصصي، تلاش كردم كه با ديد زيبايي شناسي هم به كانيهاي سازنده سنگها نگاه كنم. دوست ندارم وارد جزئيات تخصصي و كسالت آور عكاسي با ميكروسكوپ پلاريزان بشم ولي لازم ميدونم به برخي مطالب پايه اشاره كنم. در عكاسي با ميكروسكوپ سوژه در بين مجموعه‌اي از عدسي‌ها قرار مي‌گيرد (بر خلاف عكاسي با دوربين كه سوژه همواره مقابل دوربين قرار دارد) و ديافراگم در جلوي سوژه قرار گرفته و ميزان نور عبوري از نمونه را كنترل مي‌كند (به تصوير شماتيك مراجعه كنيد). نمونه هم در حقيقت يك تيغه نازك شده به ضخامت ٢٥ ميكرون از سنگ هستش كه روي لام ميكروسكپ چسبانده شده، بعداً راجع به اين جزئيات بيشتر توضيح خواهم داد

Well, first of all Arash, thanks for the kinds words. Really appreciate it!
I have always loved looking at those slivers of rocks this close. Amazing views can be seen with all of those intricate colors that one usually can not see, and the variation of lines and patterns one can find.
What type of rock is this? Now this is a cool shot!
And, if this rock you have shown here is "one tough rock", what on earth do you use to be able to cut it so thin?
25 microns? Wow!!
Yes, images such as this has been done before, but I don't think enough of them have been done.
There certainly is plenty of room for more of these type images, done artistically like you have shone here, sold as abstract art, and something which could possibly help to pay for new lenses, cameras, microscopes, or something else you really would like to have.
Market for it? I think so!
I know of a group who you just might be interested in, a photography group dedicated to macro, and a lot of that "micro" stuff too! :)
One of the owners of the site does a lot of shooting with his microscope of crystals, rocks, bacteria, other cells of which I haven't a clue about, ... and more.
If you have not visited them yet, take a look.
Lots of images to been seen there.
Here is the link.

Please keep at this Arash, as I enjoy viewing them and I'm sure there are plenty of eyes out there who would like to see them too.
Great image, nice explanation of what is involved, ... I certainly like it!
Let's see some more!
Great colours and great explanation... Wish I could read arabic :(
با سلام و یک دنیا تشکر از کامنت پر محتوایی که برام گذاشتید // همیشه از این کامنتها درس میگیرم // امیدوارم بیشتر از اینها از راهنماییهاتون بهره ببرم // مارا تنها نگذارید .. در پناه ایزد * یا علی مدد
به به شما هم آمریکا تشریف دارید .. من هم همین جا هستم .. //
خدا کمک کنه این کشور بی زبون ، این رحمت الهی به خاطر اراجیف یک عده آدم تهی مغز از حادثه ها به سلامت بگذره تا ما ایرانیها هم چنان ایرانی باقی بمونیم ..
I can read Arabic here Ana.
It says, "that Michael is one handsome fella"! :)
Arash jaan,
Glad to see you've finally started on your thin section photos. This particular work is pretty unique and there aren't a lot of people who master both photography and geology with the same passion, which makes your presentation particularly stand out. Keep posting those photos and write more about them.
Cheers
Ali
