Rossier believed that Pompe van Meerdervoort's failures in photography were due to a lack of the necessary chemicals and so he provided Maeda with a letter of recommendation to procure photographic apparatus and chemicals from a source in Shanghai. Both Maeda and Furukawa bought lenses, chemicals and albumen paper through Rossier. Maeda and Furukawa succeeded in taking a photograph with these materials on 28 October 1860, a day which is still commemorated in Fukuoka where the photograph was taken.
