Small Coffee Filter

[Mike Buckley]

The subject is an unused, metal filter made to be placed inside my wife's coffee maker. It is 1 11/16" (about 4.3 cm) in diameter.

This image isn't a favorite of mine, but it's a keeper for me mostly because of the following: Normally, I would light a subject to be mostly bright and shiny when it appears that way during the course of typical daily activities. If I had done that this time, its manufacturing imperfections, which are acceptable for its use inside a machine, would have been unacceptably unattractive at such a relatively large magnification insofar as the image itself is concerned. So, I hid those imperfections by lighting the subject (see Setup information below) to make the metal appear very dark.

Setup
The subject is hung by tape onto the background, which is a piece of white, translucent acrylic. A continuous-light lamp behind the acrylic shining toward the subject and camera casts bright light through the holes. A small continuous-light lamp is very close to the subject in the top right area. Though that lamp is shining directly onto the subject, it is outside the family of angles, which prevents almost all of the shiny metal from appearing bright and instead makes it appear very dark.

So, you were having a bit of light play in exploring a principle?

Interesting. You made me think as well.

Thank you, Mike.

Thanks for the explanation Mike. Another thread of yours which is very educative

Nice work Mike. My OCD wants to have the image rotated clockwise such that the line of holes are horizontal.

Thank you, everyone!

That's not OCD, Peter; it's just a different preference. Just for kicks and before settling on the current appearance, I tried rotating the image as you suggest and determined that it made the image look a little too static for my taste.
