Thanks everyone for your encouraging comments on my obsolete challenge photo. A slide rule is not a ruler; rather, it is a way of doing complicated math calculations (square roots, algebra, trigonometry, etc). It was in use before we had calculators and computers. I don't think of myself as that old, but I used a slide rule in high school and college and my dad, who was an engineer, used one constantly for calculations for his job. The movie Apollo 13 also shows the computer guys using slide rules to calculate how to get the astronauts home. I have forgotten how it to work it now.

All the little lines and the implication ofmath to come scared me!
No just kidding.
Its a nicely composted, well photographered, shape image. I do agree with awpollard, that a little DOF experimentation might have made it a little more interesting.

Personally, i like to see a little bit of the photographer in the image - a personal touch of sorts. It might have been nice (i'm not sure, it might have been too busy also) to have some plans or such that you would use such a ruler to create in the background instead of a plain black backdrop. I personally do not know what the exact application of such a ruler is for (i did find myself thinking how can you draw a straight line with the slider there it would make your line lumpy -because thats all i use rulers for) so for someone who is ignorant to such a rulers function, it might have mean more of a oh...OHH! image if you had left us a sneaky clue in the background.
Just an idea, like i said, it might also have been too much.

Oh and thankyou for lining up all the lines so nicely in the fram, my virgo eyes really appriciate it :D

A good shot of a great subject for the challenge. What I believe hindered your score on this shot and I don't see mentioned by commentors is the fall off of your DOF. It is a minimalistic shot with complex details (there isn't such a thing I just made that up) plenty of detail from all the lines on the rule.

Beings how the rule nearly fills the frame the slide becomes the major subject and the eye is drawn to the slide, I immediatly notice all the tack sharp lines beneath and around that area. As I study it more my periphial vision quicky spots the softness of the lines at both ends of the rule.

As close as you are to the subject this is a tough shot to pull off with Sharpness throughout. It appears that you have plenty of light, stopping down the aperture possibly as much as f/11 might have prevented the fall off the DOF.

And then the other approach might be to take the shot from an angle to deliberatly have a shallow dof on one end of the rule or other.
