Abstract
A new type of white flame arc for use in photography is described and its distribution of energy and the composite effect of this energy distribution on the transmission of the lenses and the sensitivity of supersensitive panchromatic film are shown. Of the total radiant energy almost 37 per cent is in the visible portion of the spectrum, and the new carbon shows a very considerable increase in light emitted over former carbons at the same current and voltage.
