DEAR SIR, -
In compliance with your note of the 6th inst., I send by this post
as many of the card view of Edinburgh as I have ready, viz. two
dozen; and as I expect they will reach you in the course of
to-morrow, they will, I hope, be in good time for the South London
Society's first meeting.
With regard to a paper for the
Society, on obtaining cloud negatives and printing-in skies, I fear
I cannot do anything in that way. What little I do know on the
subject is just what has appeared in the News and other
journals and a mere compilation by such an indifferent hand would
not profitably occupy the time of the South London Photographic
Society
The card picture is printed from a
stereo. negative obtained by the ordinary Fothergill process very
early (about 5a.m.) one morning in June last. The exposure,
with a pair of Horne and Thornthwhaite's small view lenses and small
stop, from beginning to end occupied sixty seconds; but the whole
plate did not receive so much time, the lens being opened and closed
very slowly by a shutter inside the camera, so that the
immediate foreground would receive at least double the exposure of
the distant castle &c. In this way I sometimes manage to
obtain natural skies; and in the negative referred to, all the
clouds present at the time may be seen in the negative, but too
dense to print with the rest of the picture.
I shall send another dozen or two
as soon as I can get them ready unless advised to the contrary.
Yours respectfully
ARCHIBALD BURNS |
