Bored at work:
When do you know you have too much time on your hands? When you go around looking for silly things to photograph:
Not exactly something you commonly associate with offices, but it was by the coffee pot.
I posted a picture earlier that needs explanation and further examples. Here's what I was photographing - it's an old floor plan. Not exactly all that interesting except for the fact that it was made before the days of CAD and has obviously been updated a number of times:
When you look a little closer, it suddenly becomes more interesting than just a piece of paper with some marks on it. You start to get an idea that it might not be what it first appears to be along with when it was first drawn.
Shot at 1:1 (uncropped, just resized) it is obvious that it's not paper at all. And it's not drawn in dark pencil or printed on it in some way.
Cropped tighter and you can see that it's woven linen, not paper at all. And it's drawn in ink. I'm constantly amazed that anyone could have the skill to draw in ink on linen, hard to make changes that way and architectural plans had to be exact. No computer to assist you. No program to automatically change the perspective.
I was using a K-S1 and DA35 macro for the close-ups, the first plan was taken with the K 24f2.8 lens on a tripod and not using any type of lighting other than the office fluorescent lights.
Then I decided to see what would happen if I added light from a small LED flashlight. Here's with the flashlight held to the side:
I thought it was interesting that the side lighting gives more of a feeling of depth, that the ink is on top of the linen.
Back in the 1930's there weren't large format printers to make copies. They had a process that used an original of lines on a media that allowed light to pass through it (paper was not a good choice, it doesn't allow all that much light to pass through), exposed it to paper that was treated with a light-sensitive material using some type of light, then used a chemical to show the lines (not exposed to the light) against a different colored background. That's the process behind blueprints and blue lines. The originals would be made out of linen (very durable), vellum, drafting paper (like tissue paper), etc. Knowing this I was curious to see what my linen original would look like if I put the flashlight under the drawing, which gives it a completely different texture.
Just some trivia and experimenting for an otherwise quiet, boring day at work.
