Persons: Sir John Frederick William Herschel (Photographer)
Date Created:
Accession Number: 1928-71
Brief Description: Experimental photogenic drawing (cyanotype) by Sir John Herschel, undated, c.1842. No image and no border (but trimmed), with apparent cloud and cross of light effects: clear vertical line right of centre, pale to right of line, darker blue bottom left quarter, cloudy especially at centre, wavy line of apparent cloud effect across middle, diagonal light cross coming from centre across top left quarter. Although it seems improbable that the effects are anything but accidental, the complete absence of image and the vertical line dividing a darker from a paler area suggest a test sheet or other deliberate experiment. The wavy line that looks like clouds is presumably a liquid or water stain, which likewise suggests a test sheet of some kind.
