109. Autochrome landscape of Madeira by Miss Acland, 1908-15
The autochrome screen process came onto the market in 1907, and in 1908 Miss Acland took both the new process and her earlier Sanger Shepherd materials with her to Madeira. Although the autochrome was much slower (several seconds exposure) and produced only one unique image, the subsequent manipulation was much easier and the quality of the colours was so superior that it immediately became her (and most other colour photographers') favourite process.
Glass autochrome 90 x 120 mm - the format of her 'Una' quarter-plate camera (Item 148).
