The Ibso shutter was made by Gauthier from 1908 onwards. It was the first everset shutter (i.e. an 'automatic' shutter, not needing to be cocked) on the market.[1] It is found on many folding cameras of the period. It has the usual limitation of evereset shutters that it cannot offer very fast speeds; the original Ibso shutter gives speeds from 1 to 1/100 second, plus 'B' and 'T'.
