A floating art installation moored on the Tyne in Newcastle, "Flow" samples the varying salinity of the river water to create sound sequences via sensors dipped into glass beakers. The pitch and timbre produced by each sensor can be adjusted by vistors, making the effect virtually random, while the results are transmitted across the river to act as background music to displays in the Baltic Gallery. Mrswoolybill has treated the same subject somewhat differently over the last few days.
The exposure here was 1/100th sec. @ f1.4. Tomorrow's photograph of the same 'mechanism' is 1/4 sec.@ f5.6.
