Field, plate, press.
Each folio begins on rope, ends on linen. The studio does not skip the darkroom in between, even when asked to.
Always large-format · always silver

Field
Two to four weeks in the field. Specimens catalogued; plates exposed in the field, never speculative.
02
Plate
Reykjavík darkroom. Each negative tested across three papers before the keep is selected.
03
