Cyanotype slideshow
This document provides information about cyanotype photography and examples. It discusses: 1. Cyanotypes, also known as blueprints, are photographic prints created through a process where objects are placed on light-sensitive paper treated with an iron salt solution and exposed to sunlight, resulting in a white image on a blue background. 2. Anna Atkins was an early photographer known for her cyanotype photos of plant specimens and her book documenting them. 3. Students are assigned to take photos exploring the concepts of positive and negative space, as well as opposites, to recreate as cyanotypes.

- 8. What is aCyanotype Photo ? • Paper is coated with an Iron Salt solution (potassium ferricyanide) and Ammonium Citrate • An object is fixed on this paper (Surface Negative) under glass
- 9. Anna Atkins(1799-1871) • Firstwoman photographer. • She became interested in Making accurate drawings of plant life, and used Photography and the Cyanotype process as her tools.

- 11. How does itwork? 4. When exposed to sun light a chemical reaction occurs. •The paper is washed and removes the exposed chemical area
- 12. • This resultsin a white image on a deep blue background • This image is the “positive” or outline of the object used. Let’s watch! https://www.youtube.com/watch?v=wEBd1XyBe_o
- 13. But wait….we aremaking cyanotypes with photo negatives not just objects! https://www.youtube.com/watch?v=I0ATpHCyYvU&nohtml5=False
- 14. Today’s Warm Up#7 – Positive & Negative Space • 2 different Photos 1.Take 1 photo with more positive space than negative. 2.Take 1 photo with more negative space than positive.
- 15. First, what ispositive space? • Positive = The occupied space. The actual object. • Negative = The space surrounding the objects. The unoccupied space.
- 16. Understanding Positive vs.Negative Space Does this photo have more negative or positive space? NEGATIVE SPACE: The sky POSITIVE SPACE: the light That’s right, More NEGATIVE space!
- 17. Understanding Positive vs.Negative Space Does this photo have more negative or positive space? NEGATIVE SPACE: blank space in doorway POSITIVE SPACE: the person, stairs, railings That’s right, More Positive space!
- 18. SO TODAY…. Lookfor • 1 Photo: More positive than negative space • FILL the frame (one way)
- 19. AND…1 Photo • Morenegative than positive • Not as much of object • Post both to your website warm ups page. • Label as #7 Positive & Negative Space.

- 23.
- 24. • Remember youare changing it to Grayscale to make the cyanotype.
- 25.
- 26. • We areusing photoshop to create the negative on transparency paper…so you can overlay or experiment with “opposites”
