The woods were illuminated by one or a combination of the following types of light:
ambient daytme indoor light
ceiling fixture with 2 75 w. incandescent lamps
LED security light
Also,use of some flash in various combinations with and without the other lights.
Light was sometimes set to shine from the top or side as well as underneath. The results were unexpected, and very colorful and bright, as the photographs show.
They are so colorful and illuminated you might wonder what tricks were used.
The answer is none.
This is digital photography and all sorts of magic can happen simply by photographing carelessly. ( sounds funny but it's true)
And if you go actually looking for special effects, just tilt the camera, or change the lighting just a tiny bit... so many ways to give the camera a chance to surprise you.
You have to wear this whole business like a loose garment, though; just be grateful for what you get. As musicians say after making a mistake, "That was not a mistake. That was an extra refrain" Or something. . (I just made that up.)
No editing was done to these photos, except cropping. I suppose this makes me a sharecropper.
The colors, although widely variable, were not the result of any colored lights or special filters or anything like that.
Camera: a 2006 Fujifilm FinePix , 6.1-megapixel DSLR, with a scratched lens.
Some of the photos had to be taken using a tripod, the "A" or aperture-favoring setting, ( makes time exposures) and the timer and photographs in the dark with no other light than what was making it through the thin pieces of wood and of course through the holes and lines of light where someday glue lines should be...
These are photos that are meant to create impressions which don't necessarily have anything to do with wood as a subject.
The light effects and surprise effects of other kinds which are one of the fun things about macro photography can make the photos into pictures, abstract of course yet reminiscent (to me, anyway) of paintings in various media, depending upon the nature of the accidental or surprise effects.
There might be a sheen sort of like like oil paint, or maybe an over-lit, washed-out area, or a certain shading of the colors of light coming through the wood, could suggest the water colors.
In other photos the sharper details could have been done in pencils or chalk, or brushed on with acrylic, maybe.
Since I am not a painter like an actual artist, this is a way to create my own pseudo- paintings- in a process similar to a sculptor or woodcarver "finding" the subject inside a block of stone or wood by carving away everything else.
The difference is that the sculptor has a goal or object in mind, but I just take what comes. Ah, digital photography!
But these photo-paintings are all accidental, if anything is seen. I see faces, landscapes, animals- there is a wolf, and more, depending on how you look. They're Rorschach-ey.
