Editorial comment on this plate:

The rare flower picture which accompanies our issue this week is from a negative by R. Clinton Fuller, a skillful and artistic amateur of Providence Rhode Island. The negative, of course, was made by magnesium “flash-light.” “One Scovill cartridge was placed on a level with the flowers, at the right of the camera,” writes Mr. Fuller, “and was used without screen or reflector. Perhaps I might have developed the negative a little further. The negative was not retouched, and the spots which show in one of the flowers are imperfections in the plate and not on the flowers.”
The picture, besides being an excellent one by a difficult method, is highly interesting from the uncommon subject which it depicts. Mr. Fuller has made a number of ”flash” pictures of flowers and all are very good. The one we give our readers is especially fine, and we consider that Mr. Fuller is to be congratulated on his eminent success.

From at least 1889-1895, Fuller was president of the Providence Camera Club. (primary sources, including: The American Annual of Photography)
