Albumen Print - The Process of Making An Albumen Print

The Process of Making An Albumen Print

  1. A piece of paper, usually 100% cotton, is coated with an emulsion of egg white (albumen) and salt (sodium chloride or ammonium chloride), then dried. The albumen seals the paper and creates a slightly glossy surface for the sensitizer to rest on.
  2. The paper is then dipped in a solution of silver nitrate and water which renders the surface sensitive to UV light.
  3. The paper is then dried in the absence of UV light.
  4. The dried, prepared paper is placed in a frame in direct contact under a negative. The negative is traditionally a glass negative with collodion emulsion, but this step can be performed with a modern silver halide negative, too. The paper with negative is then exposed to light until the image achieves the desired level of darkness, which is typically a little lighter than the end product. Though direct sunlight was used long ago, a UV exposure unit is preferable because it is more predictable, as the paper is most sensitive to ultraviolet light.
  5. A bath of sodium thiosulfate fixes the print’s exposure, preventing further darkening.
  6. Optional gold or selenium toning improves the photograph’s tone and stabilizes against fading. Depending on the toner, toning may be performed before or after fixing the print.

Because the image emerges as a direct result of exposure to light, without the aid of a developing solution, an albumen print may be said to be a printed rather than a developed photograph.

The table salt (sodium chloride) in the albumen emulsion forms silver chloride when in contact with silver nitrate. Silver chloride is unstable when exposed to light, which makes it decompose into silver and chlorine. The silver ion (Ag+) is reduced to silver (Ag) by addition of an electron during the development/printing process, and the remaining silver chloride is washed out during fixing. The black parts of the image are formed by metallic silver (Ag).

Famous quotes containing the words process, making, albumen and/or print:

    ... geometry became a symbol for human relations, except that it was better, because in geometry things never go bad. If certain things occur, if certain lines meet, an angle is born. You cannot fail. It’s not going to fail; it is eternal. I found in rules of mathematics a peace and a trust that I could not place in human beings. This sublimation was total and remained total. Thus, I’m able to avoid or manipulate or process pain.
    Louise Bourgeois (b. 1911)

    It should come as no surprise to any of us that the solution to ending bickering in families is to talk to one another more often without blaming, making judgments, or insulting one another.
    Donald C. Medeiros (20th century)

    It is not menstrual blood per se which disturbs the imagination—unstanchable as that red flood may be—but rather the albumen in the blood, the uterine shreds, placental jellyfish of the female sea. This is the chthonian matrix from which we rose. We have an evolutionary revulsion from slime, our site of biologic origins. Every month, it is woman’s fate to face the abyss of time and being, the abyss which is herself.
    Camille Paglia (b. 1947)

    And so on into winter
    Till even I have ceased
    To come as a foot printer,
    And only some slight beast
    So mousy or so foxy
    Shall print there as my proxy.
    Robert Frost (1874–1963)
