I couldn't chose between the negative "negative space" or this positive "negative space" for the Daily challenge of NEGATIVE SPACE for Tuesday 9 April 2013.
This is what we got out of the beer can after 3 months. the worm like tracks were made by my finger when I was trying to get it out of the can (in the dark) www.flackcambridge.org.uk/FLACKmagazine/FLACK_Beer_Can_Ca...

Product Description
Model 167 series negative pressure sensors are low range differential pressure transducers and transmitters. It was specially designed for 35mm DIN Rail Mount, which dramatically reduces the required mounting space and installation cost. The green and red LED indicators show the working status of the unit in the field.
The pressure range covers from 0.1”WC to 100”WC, unidirectional or bidirectional. The output can be 3-wire 0 to 5V, 0 to 10V, or 2-wire 4 to 20 mA, fully protected against short circuit and incorrect wiring. In the voltage version, the output can go down to true zero. The units are temperature compensated. The accuracy can be 0.6%, 0.4% or 0.25% at room temperature.
The patented stainless steel negative pressure transducer provides good corrosion resistance, excellent performance and long term stability.
Our unique production setup can also make special pressure range (e.g. -0.5”WC to +3.5”WC) to meet special applications.
Key Features of Alpha 167 negative pressure transducer:
Up to 15 PSI Proof Pressure on all Ranges

This week: Playing with negative space, i.e. the visual space around the main subject of the image. How do the elements relate to each other? How does negative space augment the expression of the positive space? Can negative space support or destroy the story of the subject? How does structure/colour/form of negative space impact on the image?
The album can be found here: 2021 | 52 projects.

I have to say that I've been shooting images around my town for over 30 years, so sometimes it seems like I've exhausted all possible subjects. That's why there's a second picture of my house on this same roll - nothing else interesting to photograph.

This is from a series of old negatives found in an envelope in a box of photographs at a junk store in Dewey, Oklahoma. Some seem related, others do not. Most are damaged in some way and/or poorly executed in the camera and in the dark room. Many are over- exposed.
To try to make some sense of the group, all were scanned so that obscure details might be revealed.
