EMPEROR PEDRO II (1825–1891)
Pedro de Alcântara João Carlos Leopoldo Salvador
Bibiano Francisco Xavier de Paula Leocádio Miguel
Gabriel Rafael Gonzaga de Bourbon Habsburgo e Bra-
gança was born in Rio de Janeiro on December 2, 1825.
His father, Emperor Pedro I, abdicated in 1831. Pedro II
purchased a daguerreotype camera in 1840, the year he
was declared an adult and enthroned. He also learned to
use it, thereby becoming the fi rst Brazilian-born photog-
rapher. As a patron, he encouraged the development of
photographic methods, spent vast sums on photographs
and albums, and in 1851 created the post of Imperial
Photographer, an appointment held by Buvelot & Prat
(1851), Insley Pacheco (1855), Christiano Junior (1857),
Klumb (1861), Stahl & Wahnschaffe (1862), Lopes
Cardoso (1864), Ferreira Guimarães (1866) and Guti-
errez de Padilla (1889). Pedro II traveled extensively
and collected European photographs, while ensuring
that Brazilian photography featured prominently in his
country’s pavilions at Universal Exhibitions in London
(1862), Vienna (1867), Philadelphia (1876) and Paris
(1889). Deposed and banished in 1889, he died as Pedro
de Alcântara in Paris on December 5, 1891. His collec-
tions, including albums by Benjamin Mulock and Victor
Frond, are housed at the National Library in Rio and the
Imperial Museum in Petrópolis, Brazil.

EMULSIONS
Strictly speaking these are “Suspensions” but the name
has stuck. A true emulsion is a stable mixture of two in-
compatible liquids, salad cream then a familiar example
of oil and vinegar. The original weird and wonderful
concoctions also used egg albumen as a stabiliser and
had a similar appearance and texture. In the course of
time it has changed to mean both the liquid and the dried
material on a negative or paper print.
Today we tend to think only of gelatin emulsions
although in the 19th century it was used for fewer years
than albumen or collodion.
The word was unknown at fi rst, the sensitive matter
being deposited in paper rather than onto it, Talbot’s
original process of dipping then drying. This was used
for both the negative and positive and it was not until
Niépce de St. Victor invented the albumen process in
1848 any real improvement was possible. There were
two crucial inventions here. The fi rst was a rigid base, a
glass plate. The real breakthrough was the prior prepa-
ration of a light sensitive mixture applied to the plate,
then dried, the emulsion. This invention has remained
essentially unchanged.
Niépce opened up the way for major improvements
in associated camera and lens technology because
huge negatives needed them. A positive could only be
made by contact printing and the glass plate solved the
other inherent problem with paper, its opacity. Once
the concept of applying an emulsion as a transparent
sensitised layer to a transparent inert base had been
established, photography as we know it started. Fuzzy
images and long exposures gave way to a faster and
sharper process.
