Walnut Slices

No, not the nut itself, although that's an idea for another day. These are super thin slices of a piece of walnut wood, across the vertical grain. I was a bit surprised that the light came through it at all, but I guess if you cut something thin enough, light will pass through it.

The light is just what I saw, no monkey business in CS5. The wood seems to be made up of a mesh of fibers with many airholes in it, some seen here, with what I think is dried sap partially filling them. All shots taken through a Nikon Plan APO 20x objective lens with a Canon T1i. EXIF is intact.

Pretty cool . What was it red though?

Thanks Kurt, yes, it was red from the light passing through. The normal color is brown. All I can can think of, is the dried sap in the fibers of the wood, acted like amber of a sort. I know this particular piece of wood came from a stock of wood I bought about 15 years ago at a farm auction and it was at least 25 years old then, not counting the age of the tree. All I can think of is, the sap had aged that way. If you work and then oil this wood, it has a nice dark reddish glow to it.

What really surprised me though, were the little holes in it everywhere, and the pattern of the fibers. In that first shot, you can see a square pattern of heavier fibers, then another pattern with a sponge look to them grown on the square pattern, with larger holes all though it. The actual angle you are looking from is if you cut the tree straight across the grain of the trunk, like you were cutting it down, then looked down on the rings of the tree.

good series Mitch...i always like to see and read something different/unusual and with proper knowledge about the subject...which you always posts...did u mean light did not pass through the thin sliced subject(walnut wood)...

Thanks Rakesh. Light did pass through the very thin slice I made from the original piece. I was not sure if it would or not, but it came through enough for me to get a picture. I did have to use ISO 400 and shutter speed was 1/15", where my normal settings for lighter subjects is Tv mode, ISO 100 and 1/200".
