Hi, as mentioned in my reply to the Arizona Rainbow Wood thread that I started yesterday, this post is going extreme close-up. I've heard that Arizona petrified wood is sometimes so well preserved that you can actually make out the original cellular pattern of the wood. So I began wondering if I could detect it in my own tumbled petwood from Arizona. I had a closer examination of the pix I posted yesterday, and since my camera (Canon Powershot S2 IS) has a close-focus right up to touching the lense, plus give 5.0 megapixel images, that leaves lots of room for blowing up photos before you exceed the image quality of computer monitors. Anyway, enough yakking. This is the only pic I have so far that I'm certain shows the original cell-pattern of the wood. This is the raw pic that I posted yesterday:  And here is the yellowy area in the upper-right, enlarged to its maximum. I'm thrilled -- this actually shows the underlying finely-dotted checkerboard pattern of individual cells that made up the wood when the tree was alive, some 225 million years ago. Too cool.  |

Dear Santa, I have been a good rockhound. Please bring me a Canon Powershot S2 IS.

Hey Don, that is pretty impressive for a digital camera! The only way that I can get that detail is by using an industrial scanner that I have. It has optical scanning capability of 4800x4800.
It's alway great to be able to find that kind of detail in your wood. I love it!

Wow, that's just cool. Someday I'll get a new dc and the
first thing I want is absolute optimum macro on it. That's
so awesome to be able to get that close.

Rolling-
I've been looking at that same camera over the past week and am amazed at all the cool features. Don't think I'll be getting a new cam anytime soon. Wife would kill me if I dropped another 5 or 6 hundred on another digital camera. My Fuji FinePix is about 3 1/2 years old and I'm ready for an upgrade. So many toys....so little money....LOL.
Anyway, thanks for showing me your macros...really cool stuff and the wood is awesome.

RS Great photos, but if we can all just wait a few more years we'll take a pic of pet wood or other item thats millions of years old and we'll get a 30 second clip of the tree being planted or the rock actually forming.  Well it might be 10 or 15 more years but its coming. Merry Christmas,Pete |

Those are awesome close ups Don! If you get any closer we will be looking at rock atoms. Thanx.

Thanks for all the kind comments!
I too was surprised that a digital camera could show this level of detail. Makes me wonder if I shouldn't go back and look at some of the other petwood I've tumbled to look for similar very-fine structural details.
I still have to take and post macro pics from a small amount of some different material that was in the same barrel as this AZ petwood. It should make for good close-up pics, but I'll leave that until the new year... for the next two weeks my indoor photo spot is occupied with a nativity scene, and outdoor pics are too cold at this time of year.
So no more pics until January, and until then.....MERRY CHRISTMAS AND A HAPPY NEW YEAR!!!!
