Door voorwerpen of negatieven op het behandelde oppervlak te leggen en te belichten, ontstaat een afdruk die wordt ontwikkeld met water.&nbsp;\u2028\u2028<br><br>Lichtgevoeligheid: Een mengsel van ammoniumijzer citraat en kaliumhexacyanoferraat wordt op een drager (meestal papier of textiel) aangebracht.<br><br>Proces: Na droging worden voorwerpen (bladeren, bloemen) of transparante negatieven op het materiaal geplaatst.<br><br>Belichting: Blootstelling aan UV-licht (zonlicht) zorgt ervoor dat de onbedekte delen blauw kleuren.<br><br>Ontwikkeling: Het materiaal wordt gespoeld in water, waardoor de overtollige chemicali\u00ebn verdwijnen en de afbeelding (de bedekte delen blijven wit) permanent wordt.\u2028\u2028<br><br>Toepassingen:<br>Botanische kunst: Het maken van afdrukken van planten en bladeren.<br>Fotografie: Het afdrukken van negatieven tot &#8216;zonnefoto&#8217;s&#8217;.<br>Textielkunst: Het bedrukken van stoffen met unieke patronen.\u2028<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Workshop volgen ?
